This application is related to U.S. patent application entitled “System and Method of Dynamically Providing Priority For Network Communications”, Ser. No. 10/787,995 filed Feb. 26, 2004, inventor: Singh et al., which is also assigned to the present assignee.
Software applications and application servers may typically include many different applications and services within those applications (e.g. services configured as software modules or other forms) that can be invoked and executed. When a service is invoked, it may in turn invoke the execution of other internal services. Each service may generate network calls such as a database call, an external application call, and other types of network communications that generate network traffic. In prior systems, the network communications coming from a selected application server could be given priority processing where the priority was given to the application server as a whole. However, providing priority or other special processing to a particular service within the application server was not performed. One reason is that network communications at a service-level could not be identified between different services of the same application server/software. Relationships between services at run-time (e.g. what services and/or how many services are being called in a stack) may also be useful.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various example systems, methods, and so on that illustrate various example embodiments of aspects of the invention. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that one element may be designed as multiple elements or that multiple elements may be designed as one element. An element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.
A software application may include any number of services that are configured to perform a variety of functions. A service can be configured as a software module, routine, or other type of software component that is configured to perform a desired function. One example service may be a purchase order generator that, as the name implies, generates purchase orders for a transaction. When the purchase order generator service is invoked and executed, it may generate any number of network calls that result in network communications (e.g. TCP/IP network traffic). The network calls can be, for example, a database call, a lightweight directory access protocol (LDAP) call, an external application call like a credit card validation, and so on. These types of network-oriented transactions generate network communications and network traffic. In order to provide special processing for the purchase order generator service or other selected service, the network communications generated by or associated with the purchase order generator need to be identified. One type of special processing may include prioritizing the network communications so that they can be processed with priority over other network communications, even given priority over other communications from the same software application.
The following includes definitions of selected terms employed herein. The definitions include various examples and/or forms of components that fall within the scope of a term and that may be used for implementation. The examples are not intended to be limiting. Both singular and plural forms of terms may be within the definitions.
As used in this application, the term “computer component” refers to a computer-related entity, either hardware, firmware, software, a combination thereof, or software in execution. For example, a computer component can be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and a computer. By way of illustration, both an application running on a server and the server can be computer components. One or more computer components can reside within a process and/or thread of execution and a computer component can be localized on one computer and/or distributed between two or more computers.
“Computer communication”, as used herein, refers to a communication between two or more computing devices (e.g., computer, personal digital assistant, cellular telephone) and can be, for example, a network transfer, a file transfer, an applet transfer, an email, a hypertext transfer protocol (HTTP) transfer, and so on. A computer communication can occur across, for example, a wireless system (e.g., IEEE 802.11), an Ethernet system (e.g., IEEE 802.3), a token ring system (e.g., IEEE 802.5), a local area network (LAN), a wide area network (WAN), a point-to-point system, a circuit switching system, a packet switching system, and so on.
“Computer-readable medium”, as used herein, refers to a medium that participates in directly or indirectly providing signals, instructions and/or data. A computer-readable medium may take forms, including, but not limited to, non-volatile media, and volatile media. Non-volatile media may include, for example, optical or magnetic disks and so on. Volatile media may include, for example, optical or magnetic disks, dynamic memory and the like. Common forms of a computer-readable medium include, but are not limited to, a floppy disk, a flexible disk, a hard disk, a magnetic tape, other magnetic medium, a CD-ROM, other optical medium, other physical medium with patterns of holes, a RAM, a ROM, an EPROM, a FLASH-EPROM, or other memory chip or card, a memory stick, and other media from which a computer, a processor or other electronic device can read.
“Data store”, as used herein, refers to a physical and/or logical entity that can store data. A data store may be, for example, a database, a table, a file, a list, a queue, a heap, a memory, a register, and so on. A data store may reside in one logical and/or physical entity and/or may be distributed between two or more logical and/or physical entities.
“Logic”, as used herein, includes but is not limited to hardware, firmware, software and/or combinations of each to perform a function(s) or an action(s), and/or to cause a function or action from another logic, method, and/or system. For example, based on a desired application or needs, logic may include a software controlled microprocessor, discrete logic like an application specific integrated circuit (ASIC), a programmed logic device, a memory device containing instructions, or the like. Logic may include one or more gates, combinations of gates, or other circuit components. Logic may also be fully embodied as software. Where multiple logical logics are described, it may be possible to incorporate the multiple logical logics into one physical logic. Similarly, where a single logical logic is described, it may be possible to distribute that single logical logic between multiple physical logics.
An “operable connection”, or a connection by which entities are “operably connected”, is one in which signals, physical communications, and/or logical communications may be sent and/or received. Typically, an operable connection includes a physical interface, an electrical interface, and/or a data interface, but it is to be noted that an operable connection may include differing combinations of these or other types of connections sufficient to allow operable control. For example, two entities can be operably connected by being able to communicate signals to each other directly or through one or more intermediate entities like a processor, operating system, a logic, software, or other entity. Logical and/or physical communication channels can be used to create an operable connection.
“Signal”, as used herein, includes but is not limited to one or more electrical or optical signals, analog or digital signals, data, one or more computer or processor instructions, messages, a bit or bit stream, or other means that can be received, transmitted and/or detected.
“Software”, as used herein, includes but is not limited to, one or more computer or processor instructions that can be read, interpreted, compiled, and/or executed and that cause a computer, processor, or other electronic device to perform functions, actions and/or behave in a desired manner. The instructions may be embodied in various forms like routines, algorithms, modules, methods, threads, and/or programs including separate applications or code from dynamically linked libraries. Software may also be implemented in a variety of executable and/or loadable forms including, but not limited to, a stand-alone program, a function call (local and/or remote), a servelet, an applet, instructions stored in a memory, part of an operating system or other types of executable instructions. It will be appreciated by one of ordinary skill in the art that the form of software may be dependent on, for example, requirements of a desired application, the environment in which it runs, and/or the desires of a designer/programmer or the like. It will also be appreciated that computer-readable and/or executable instructions can be located in one logic and/or distributed between two or more communicating, co-operating, and/or parallel processing logics and thus can be loaded and/or executed in serial, parallel, massively parallel and other manners.
Suitable software for implementing the various components of the example systems and methods described herein include programming languages and tools like Java, Pascal, C#, C++, C, CGI, Perl, SQL, APIs, SDKs, assembly, firmware, microcode, and/or other languages and tools. Software, whether an entire system or a component of a system, may be embodied as an article of manufacture and maintained or provided as part of a computer-readable medium as defined previously. Another form of the software may include signals that transmit program code of the software to a recipient over a network or other communication medium. Thus, in one example, a computer-readable medium has a form of signals that represent the software/firmware as it is downloaded from a web server to a user. In another example, the computer-readable medium has a form of the software/firmware as it is maintained on the web server. Other forms may also be used.
“User”, as used herein, includes but is not limited to one or more persons, software, computers or other devices, or combinations of these.
Some portions of the detailed descriptions that follow are presented in terms of algorithms and symbolic representations of operations on data bits within a memory. These algorithmic descriptions and representations are the means used by those skilled in the art to convey the substance of their work to others. An algorithm is here, and generally, conceived to be a sequence of operations that produce a result. The operations may include physical manipulations of physical quantities. Usually, though not necessarily, the physical quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated in a logic and the like.
It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. It should be borne in mind, however, that these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise, it is appreciated that throughout the description, terms like processing, computing, calculating, determining, displaying, or the like, refer to actions and processes of a computer system, logic, processor, or similar electronic device that manipulates and transforms data represented as physical (electronic) quantities.
In one example, the application server 110 can be a server program in a computer or in a distributed network that provides business logic for the software application 105. The application server 110 can include a suite of software that helps programmers isolate the business logic in the application from the platform-related code. The application server 110 can also be configured to handle the application logic and connectivity found in client-server applications and can offer features such as transaction management, clustering and failover, load balancing, open database connectivity (ODBC) support, and other features.
In general, an application server can be configured to range from a small footprint, using web-based processors for intelligent applications or remote embedded devices, to complete environments for assembling, deploying, and maintaining scalable multi-tier applications across an enterprise. The application server 110 can be configured to handle application operations between browser-based computers (e.g. one or more clients/users 115) and an organization's back-end business applications and/or databases. For example, the user 115 can access a network 120 such as the Internet and can establish an operable connection with the application server 110 to establish communications between them. Any type of computer communication can be used. The application server 110 can act as a translator allowing the client 115 to, for example, search an on-line database, to purchase products, and/or to perform other available on-line operations or services.
In the following example, assume that a purchase order generator service is identified as a priority service. Further assume that the service identification logic 100 is configured to identify the network communications associated with the purchase order generator so that the network communications can receive priority processing. Although network communications and other operations may be distinguishable between two different software applications and/or application servers, network communications between two different internal services (e.g. purchasing modules, invoicing modules, and others) of the software application 105 are not readily distinguishable. For example in
Thus, in one example, the service identification logic 100 is configured to monitor the execution of the software application 105 and to identify the executing code associated with the priority service (e.g. the purchase order generator). Once the priority service is identified, then the service identification logic 100 can identify network communications that are generated by and/or associated with the priority service. As one example, the service identification logic 100 can be embodied as software that is independent and external to the software application 105 so that the code of the software application 105 does not need to be changed. The service identification logic 100 can be executed concurrently with the software application 105 and can monitor events that occur within the software application 105 through features or other operations available through the application server 110, an operating system, and/or other tools available in the computing environment.
From the monitoring, the name of a service being processed can be identified by the service identification logic 100 and can be compared to a list of priority services 125. The list of priority services 125 may include one or more service names that have been previously selected for priority processing. If the service identified is a priority service, a notification logic 130 can be configured to notify one or more network devices 135 to provide priority processing for the network communications associated with the identified service. For example, one or more identification parameters can be identified from the network communications of the priority service and the identification parameters can then be transmitted to the network devices 135. Additionally, relationships between the services (at run-time) can be determined by identifying the services that are invoked by another service. Thus, from monitoring the execution of the application 105, the service identification logic 100 can be configured to determine and build the relationships of services. For example, Service 1 has invoked services S3 and S5, and thus are related (e.g. S3 and S5 are child services of Service 1). Knowing the relationships can allow the system to automatically provide priority to all child-services of a priority service, if so desired.
The list of priority services 125 can be pre-generated based on selections made by a user (e.g. a system administrator). In that regard, a logic can be provided (not shown) that is configured to determine installed services within the software application 105 and allow a user to select which services are to be given priority processing. The list of priority services 125 can then be generated from the services selected from the installed services. This feature will be described in greater detail with reference to
In another example, the service identification logic 100 can be configured to identify network communications of a selected service by monitoring for a socket allocated to the selected service. The socket will typically be assigned a network tuple needed to make a physical network connection and facilitate network communications. The network tuple may include a source Internet Protocol (IP) address and port, and a target IP address and port. Thus, in one example, data from the network tuple associated with the socket can be used to identify the network communications of a service. Once a service is identified as a priority service, it can be further monitored for an occurrence of a socket allocation. Since a socket is a mechanism for creating a virtual communication connection between processes or other objects, the opening of a socket indicates that network communication will occur. The network tuple will form part of an Internet protocol (IP) packet and will be used to direct the communications between a source object (e.g. the identified service) and a target object over the network (e.g. the user 115). The IP packet can include four address components, for example, a source IP address, a source port value, a target IP address, and a target port value. The IP packet can be transmitted to the network device 135 that can translate the IP packet and send it through the network 120 to the appropriate target.
Each IP packet can be uniquely identified using the four address components. Furthermore, each service processed by the application server 110 will be dynamically assigned a unique source port value when a socket is allocated for the service. Thus in one example, once a socket is identified, the source port value can be retrieved for that socket and the source port value can be used to identify network communications associated with that socket and thus, that selected service. The notification logic 130 can then transmit the source port value to the network device 135 along with instructions to prioritize network communications associated with the selected service. The instructions can cause the network devices 135 to monitor network communications (e.g. IP packets) that include the identified source port value and mark those packets for priority processing. Thus, the network devices 135, at a hardware level, may at least identify and mark selected network communications that are processed through the network device 135 associated with the priority service based on at least the source port value.
For example, the service identification logic code 215 can be configured to monitor events associated with the executing code 210 in order to identify and determine whether the executing code 210 is associated with a priority service or not, as described previously. This can be performed by listening to events generated by the JVM 205. Thus, the service identification logic code 215 can be independent and non-intrusive to the executing code 210. Based on the monitored events, the service identification logic code 215 can determine whether the executing code 210 is a priority service and, if so, monitor for an allocation of a socket. As explained previously, a source port value assigned to the socket can then be retrieved and used to identify network communications associated with this socket and, thus, this service. Other portions of the source address assigned to the socket can also be used to identity the network communications.
Example methods may be better appreciated with reference to the flow diagrams of
In the flow diagrams, blocks denote “processing blocks” that may be implemented with logic. In the case where the logic may be software, a flow diagram does not depict syntax for any particular programming language, methodology, or style (e.g., procedural, object-oriented). Rather, a flow diagram illustrates functional information one skilled in the art may employ to develop logic to perform the illustrated processing. It will be appreciated that in some examples, program elements like temporary variables, routine loops, and so on are not shown. It will be further appreciated that electronic and software logic may involve dynamic and flexible processes so that the illustrated blocks can be performed in other sequences that are different from those shown and/or that blocks may be combined or separated into multiple components. It will be appreciated that the processes may be implemented using various programming approaches like machine language, procedural, object oriented and/or artificial intelligence techniques. The foregoing applies to all methodologies herein.
At block 315, it is determined whether the web service is a priority service. In one example, this can be performed by comparing the name or other identification of the web service to a predefined list of priority services. If the web service is not a priority service, the process can stop monitoring that service and continue monitoring the execution of the software for the next service that is processed (block 305).
If the web service is a priority service (block 315), network communications associated with the web service are identified (block 320). This may include determining identification information/parameters that can uniquely associate the network communications with the web service. For example, if the network communications are processed using a socket connection, a network tuple may be allocated to the socket connection. In one example, the network tuple may include four components like a source IP address, a source port value, a target IP address, an a target port value that become part of an IP packet. Some portion or all of the network tuple components can be used to identify the network communications of the web service.
For example, the source port value can be dynamically allocated for a socket by the application server and is uniquely associated to the web service and the socket. Since every IP packet that is associated with the web service and its current socket will include the same source port value, it may be used to identify the network communications (e.g. IP packets) associated with the web service (block 325). At least the source port value, for example, can be used by network devices (e.g. routers, traffic shapers, and the like) to monitor network communications as they are being processed to determine which network communications match the source port value.
The process can begin by monitoring the execution of the software (block 405). For example, the process can listen to or monitor for events that occur within the Java virtual machine during execution of the software. This type of information can be retrieved from, for example, a run-time memory. In this manner, the monitoring is external to the software and does not interfere with its processing. The process watches/monitors for a thread to be executed (block 410). For example, when an event occurs in response to a thread being allocated, it can be assumed that a new service/module is being invoked and processed. Events that are triggered by the thread are monitored (block 415) to identify what is being processed by the thread. By reviewing information/parameters from the events such as class names, the identity of the service being processed can be determined.
At block 420, a determination is made whether the identified service associated with the thread is a priority service. For example, class names associated with events can be determined where a class name can be used to identify the service being processed. If a class name identified from the thread matches a class name of a priority service, then the process knows that the thread is processing a priority service. A list of priority services, including their class names, can be maintained and used for this determination. If the service identified is not a priority service, then monitoring of the thread is stopped since it is processing a non-priority service (block 425). The process can continue monitoring the execution of the software for new threads that are allocated (block 405).
If a priority service is being processed by the thread at block 420, then the process continues to monitor the execution of the thread. For example, the process can monitor for events associated with a socket being opened or otherwise allocated to the thread (block 430). As explained previously, a socket can be used for network communications. Thus, when an event indicates that a socket is opened, the process knows that the thread will be performing network communications. In other words, the service is a web service. When the socket is opened, network communication parameters, which are allocated to the socket, are retrieved (block 435). This can include IP packet data, a source port value, and/or other values as desired.
In one example, the source port value is dynamically assigned to a socket when the socket is opened. Different services being concurrently processed by the application server will perform network communications through different sockets where each socket is only assigned to one service. Although two different services may have the same source IP address since the services are part of the same application server, the different services will be assigned different source port values for their respectively assigned sockets. The source port value can, thus, be used to identify the service that is using the socket and can identify the network communications that are processed through the socket. This is because the network communications coming from a service will have the same source port value in each IP packet.
Once the source port value is determined for a priority service, a notice can be transmitted to one or more network devices that process network traffic (block 440). The notice can be a data packet or other signal transmission that includes at least the source port value. The network device(s) can then use the source port value to mark all network traffic having the same source port value as priority network traffic. In this manner, the network communications associated with the priority service can receive priority processing based on the source port value.
With further reference to
In this example, at least the source port value is the mechanism used to identify network communications that are associated with a priority service. This allows the network communications to be marked and processed with priority. However, once the identify of the service is determined, any type of special processing can be initiated for the service besides or in addition to giving it priority processing.
In any event, the process of
With reference to
Executable instructions 625 can cause the computer to respond to one or more data entry selection signals that are received indicative of the selection device 610 selecting one or more data entries from the set of data entries displayed (e.g. clicking on and selecting a displayed service). The selected services can be marked as priority services. In response to the one or more data entry selection signals, one or more entries can be caused to be stored in a list of priority services 630 where an entry represents a service selected to receive priority processing. The generated list 630 can be used, for example, as the list of priority services 125 of
The graphical user interface 600 can also include processor executable instructions to cause a processor to provide an option to initiate identification of installed services in the application server. In the case where the list of installed services 620 is not generated, the user can select the option to initiate the identification. In response to the option being selected, the graphical user interface 600 can cause logic (not shown) to identify the installed services in the application server.

A data field 840 in the packet 800 can include various information intended for the receiving computer component and/or logic (e.g. a router). In one example, the data field 840 can include priority identification data like a source port value of a selected service that is to receive priority. As explained previously, the source port value can be used by a router to identify network communications processed by the router. If a network communication (e.g. an IP packet) has a source port value that matches the source port value from the data field 840, then the network communication is associated with the priority service. The data field 840 can also include instructions that tell the network device what to do with the identified network communications such as mark it for priority processing.
In this manner, the data packet 800 can be configured for transmitting priority identification data to one or more network devices. The data field 840 can be configured with one or more sub-fields like a first field that stores the instructions to the network device and a second field that stores the identification data (e.g. source port value). For example, the first field can be configured to store instructions to mark selected network communications for priority processing where the selected network communications are associated with a priority web service. The second field stores a unique identifier allocated to network communications associated with the priority web service where the unique identifier can be used by the one or more network devices to identify the selected network communications from network traffic being processed by the one or more network devices.
The data packet 800 can also include an error detecting and/or correcting field 850 where a computer component and/or logic can determine if it has properly received the packet 800. While five fields are illustrated in a certain order, it is to be appreciated that a greater and/or lesser number of fields arranged in different orders can be present in example data packets. It will be further appreciated that the data packet can be configured in a variety of forms such as at least one of: a computer-readable medium, a carrier wave, and one or more signals that can be propagated over a transmission medium.
With the above described systems and methods, the identify of different services installed on an application can be determined. A user can select any available service like a purchase order generator service and mark it to receive priority. All network communications that are generated by the selected service can then be identified and be given priority processing on an individual level rather than giving priority to all network communications generated by the application software from all installed services.
While the figures illustrate various actions occurring in serial, it is to be appreciated that various actions could occur substantially in parallel, can occur in different orders, and/or can occur at different points in time. Furthermore, while a certain number of processing blocks (e.g. processes) are described in each figure, it is to be appreciated that a greater and/or lesser number of processes could be employed and that lightweight processes, regular processes, threads, and other approaches could be employed.
In one example, the methodologies are implemented as processor executable instructions and/or operations that can be provided by a computer-readable medium. Thus, in one example, a computer-readable medium may store and/or provide processor executable instructions operable to perform one or more of the described methods.
While example systems, methods, and so on have been illustrated by describing examples, and while the examples have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the systems, methods, and so on described herein. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention is not limited to the specific details, the representative apparatus, and illustrative examples shown and described. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. Furthermore, the preceding description is not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.
To the extent that the term “includes” or “including” is employed in the detailed description or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed in the detailed description or claims (e.g., A or B) it is intended to mean “A or B or both”. When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995).
