Planning for ContentDirector agent configuration

Information to gather for CDA configuration

ContentDirector agent configuration will require less time if you make some decisions and gather some information before you start configuring the CDA. Determine the following:

Whether you want to configure the CDA as a group leader or group member
The IP address of the core application, if you are configuring a group leader
The IP address of the group leader, if you are using a unicast network and are configuring a group member
The IP addresses of any firewalls between the CDA and other ContentDirector devices (for example, the core application, group leaders, and group members)
The port number to use for core application, if you are configuring a group leader and do not want to use the default port number (8080)
You might need to change the port number if an application uses the same port, for example, RealProxy^TM Server, which uses port 8080 for HTTP encapsulation. See Transport port conflicts for more information on reconfiguring the default port.

This section provides information to help you determine the types of information required for your deployment.

The following illustration shows the traffic flow in a typical ContentDirector deployment. See ContentDirector port requirements for more information about ContentDirector port traffic.

ContentDirector port requirements

The following table describes the protocols and ports required for ContentDirector communication.

Protocol	Transport	Traffic description	Explanation
GCDP	TCP	Sent from the core application to port 3132 on the group leader Sent from the group leader to port 8080 on the core application	The Global Content Distribution Protocol (GCDP) is used to deliver core application commands and data to group leaders.
MCTP	UDP	Sent from the group leader to port 1100 on the group member	The Multicast Content Transfer Protocol (MCTP) is used to distribute data from group leaders to group members.

Traffic description

Explanation

GCDP

TCP

Sent from the core application to port 3132 on the group leader

Sent from the group leader to port 8080 on the core application

The Global Content Distribution Protocol (GCDP) is used to deliver core application commands and data to group leaders.

MCTP

UDP

Sent from the group leader to port 1100 on the group member

The Multicast Content Transfer Protocol (MCTP) is used to distribute data from group leaders to group members.
