Virtualized network topology

Last Updated : Jan 09, 2026 |

You can deploy Avaya SBC on Avaya Solutions Platform 130 Appliance R6.0.x to support multiple topologies for both single and multiple data center environments.

The required SBC size depends only on session capacity, not on the number of switches or racks the servers use. Each topology enables you to separate management. You can also choose between VLAN or flat-LAN configurations for increased flexibility.

The following table describes the networking components for these virtualized environments:
