Geographical distribution overview

Last Updated : May 25, 2020 |

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. For more information about configuring Session Manager and Communication Manager, see Administering Avaya Aura® Session Manager and Administering Avaya Aura® Communication Manager.
