Implementing Communication Manager on a data network

Multi-Site with a dedicated "control" network routed
Figure 88: Multi-site with a dedicated control network routed
The above example shows two sites, one the primary media server cluster, and a second with a
backup cluster. To provide protection for the media server to IPSI communications, Avaya
recommends the use of a dedicated control network. For backup cluster redundancy, it is still a
requirement that each media server pair be able to communicate across the customer network
to control remote port networks.
It is not a requirement, nor is it recommended, that the voice (or data) networks be able to
communicate with the control networks. It is recommended that strong access lists or a firewall
separate the voice/data networks from the control network, to limit traffic allowed from the
outside networks. Tight control of the rule set can then allow for specific stations to access the
Web interface of the S8700 Media Servers. Once again, IP connectivity is required between
media server clusters and the IPSIs of any port network requiring control.
This is the most prevalent design in large corporate infrastructures supporting the Avaya S8700
Media Server IP-Connect configuration.
Advantages: - Provides a control point to limit traffic allowed on the control network. With
additional media servers it can provide protection against utilization failures and spanning tree
recalculations. Will allow TDM connections to continue during specific network failures.
Disadvantages: - Requires additional VLANs or dedicated media server/router interfaces.
