2.2 Load Sharing
2.2.1 Introduction to Load Sharing
In a large VoIP network constructed using the XE IP PBX, PS overload and network
load imbalance may occur due to the following reasons:
z
Difference of PSs in physical performance and network environment
z
Significant network structure changes, for example, addition of a large number of
gateways
To ensure healthy operation of the voice network, the XE IP PBX provides the load
sharing mechanism, allowing you to configure load distribution policies to dynamically
tune load distribution.
