Geographical distribution overview

Last Updated : Jun 10, 2026 |

In a geographically distributed system, resources are deployed in multiple data centers to reduce media delays. For this purpose, the following components are deployed in each data center:

  • Avaya Aura® Media Server

  • Avaya Aura® Session Border Controller

  • Avaya Aura® Web Gateway

  • Web Collaboration Server

  • Avaya Aura® Session Manager

  • Avaya Aura® Communication Manager

  • Avaya Aura® Device Services

In a geographically distributed system, you must also install the following two components:

  • Global Server Load Balancing (GSLB), which provides different routes and addresses based on the location of the client.

  • Load balancer, which balances traffic between two or more Avaya Aura® Web Gateway nodes, which may be located in the same data center or in different data centers.

Avaya Aura® Session Manager and Avaya Aura® Communication Manager are important for call routing. To optimize media delays for point-to-point calls, deploy these components in a distributed manner across your data centers. The way in which these components are geographically distributed is outside the scope of this document.
