Avaya SBC can be deployed in a single data center or in a dual data center. However, for a dual data center, the following network configuration requirements between the data centers must be met:

• Bandwidth must be equal to or greater than 1 Gbps.

• The network must be reliable. That is, no application-level handling of network disconnects is provided.

• Network latency must be within the following performance limits:

  • Less than or equal to 50 ms — Recommended.

  • 50–100 ms — Some delays in navigation and simple operations. Complex operations, like editing or saving SIP users that traverse multiple systems, may take substantially longer.

  • 100–150 ms — Further performance degradation possible.

This latency information is provided as guidance. Actual performance will depend on the actual network latency between Avaya SBC servers.
