In this section:
The SBC Core supports the relaying TCP traffic (in addition to SIP/SDP traffic) with the use of a Relay Profile object and a Relay Port configuration on a per-Zone basis. The Relay Port is used to establish end-to-end TCP relay connections between the TCP endpoints and the servers. the SBC terminates the connections initiated by the device and initiates connections towards the respective servers. TCP traffic policing and routing are performed based on the SBC local IP and port on which the connection is terminated. TCP packets are relayed with any content, for example, HTTP, XCAP, XMPP, or USS.
Refer to Zone - Relay Port - CLI for Relay Port configuration details.
% set profiles services relayProfile <relayProfile name> maxEgressConn <value> maxEgressRate <# connections/second> maxIngressConn <value> maxIngressRate <# connections/second> tcp keepAlive <1-1000 seconds>
The Relay Profile parameters are as shown:
% set profiles services relayProfile MyRelayProfile maxEgressConn 1000 maxEgressRate 50 maxIngressConn 1000 maxIngressRate 50 tcp keepAlive 300 % show profiles services relayProfile MyRelayProfile maxIngressRate 50; maxIngressConn 1000; maxEgressRate 50; maxEgressConn 1000; tcp { keepAlive 300; }
