Steering Pools

Steering pools define sets of ports that are used for steering media flows through the Oracle® Enterprise Session Border Controller. These selected ports are used to modify the SDP to cause receiving session agents to direct their media toward this system. Media can be sent along the best quality path using these addresses and ports instead of traversing the shortest path or the BGP-4 path.

For example, when the Oracle® Enterprise Session Border Controller is communicating with a SIP device in a specific realm defined by a steering pool, it uses the IP address and port number from the steering pool’s range of ports to direct the media. The port the Oracle® Enterprise Session Border Controller chooses to use is identified in the SDP part of the message.

Note:

The values entered in the steering pool are used when the system provides NAT, PAT, and VLAN translation.
