This diagram shows two boxes on the far left side: one labeled FTP Client and the other labeled HTTP WebDAV Client. Both have lines exiting on their right sides that connect to a circle labeled Network.
Network has a line on its right side that connects to a box labeled Protocol Server, which is inside a larger box labeled Oracle XML DB Repository. In addition to including the box labeled Protocol Server, the Oracle XML DB Repository box includes four other sub-boxes: FTP Server, HTTP/WebDAV Server, Foldering, Configuration Management, and ACL Security. Protocol Server has a single line on its right side that branches to connect to FTP Server and HTTP/WebDAV Server. FTP Server and HTTP/WebDAV Server each have a line on their right sides that connects to a vertical line (functioning as a bracket) that encompasses the three boxes labeled Foldering, Configuration Management, and ACL Security.
