Geographical distribution overview
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

General geographical distribution topology
In this topology example, there are two data centers with one Avaya Aura
®
Web Gateway in each
data center. For simplicity, System Manager is deployed in Data Center 1 (DC1), while Session
Manager, Communication Manager, and Avaya Aura
®
Device Services are deployed in all data
centers.
