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:
Relay Profile Parameters
Parameter | Length/Range | Description |
---|---|---|
| 1-23 characters | The name of the relay profile to assign to a relayPort. |
| >0 | The maximum number of simultaneous egress connections for this Relay Profile. (default = 1000) |
| >0 | The maximum rate, in seconds, at which egress connections are accepted. (default = 50) |
| >0 | The maximum number of simultaneous ingress connections for this Relay Profile. (default = 1000) |
| >0 | The maximum rate, in seconds, at which ingress connections are accepted. (default = 50) |
| 1-1000 seconds | The TCP keep-alive interval in seconds. (default = 200) |
