This image is an illustration that identifies the ports and protocols for the communication between targets and proxy controllers, between proxy controllers and the Enterprise Controller, and between the Enterprise Controller and browsers. To the left, there are three servers placed vertically, which are named Server 1, Server 2, and Server 3 respectively. Each of these servers have an OS Agent and a Service Processor. A Ports 21165, 8002, 8004 block is placed horizontally next to each of the servers respectively. Next to these Ports 21165, 8002, 8004 blocks, there are two Proxy Controllers placed vertically. The OS Agent of Server 1 is indicated to communicate with the first Proxy Controller through its respective Ports 21165, 8002, 8004 block. The OS Agent of Server 2 is indicated to communicate with the first Proxy Controller through its respective Ports 21165, 8002, 8004 block. The OS Agent of Server 3 is indicated to communicate with the second Proxy Controller through its respective Ports 21165, 8002, 8004 block. Below these Proxy Controller blocks, there are two Hosts, Global Zone and Oracle VM Server for SPARC respectively. The Global Zone host consists of two Non Global Zones and the Oracle VM Server for SPARC host consists of two Logical Domains. Below these hosts, there is a NFS Server (optional) block. The two Non Global Zones and two Logical Domains of the hosts are indicated to communicate with this optional NFS Server. This NFS Server can optionally communicate with the Enterprise Controller. These two hosts communicate with the second Proxy Controller through Port 21165. The two Proxy Controllers are indicated to communicate with the Enterprise Controller through Port 443. Now, the Enterprise Controller communicates with the Browser through Port 80, 9443. The Enterprise Controller also communicates with the Knowledge Base Vendor through HTTP, HTTPS, FTP block and Optional HTTP proxy with user/pass block. The Browser is also indicated to communicate with the Oracle VM Server for SPARC host through VNC Applet Port 10,000 and up (optional) block.
