IP endpoint recovery
The link recovery process follows these steps:
1.While SLS is enabled and processing, the media gateway continues to seek an alternative media gateway controller.
2.If Avaya Communication Manager accepts the registration then the active IP to IP calls that shuffle are preserved.
3.The SLS application stops processing any new calls and goes to inactive mode.
IP endpoint recovery
Avaya’s distributed
IP endpoint recovery
The Avaya servers are designed to have a scalable architecture with different server components. These components provide processing and relay signaling information between Communication Manager and the Avaya IP endpoints. The system architecture is inherently distributed, providing the scalability to support a large number of endpoints and the flexibility to work in various network configurations.
This distributed nature of the architecture introduces additional complexity in dealing with endpoint recovery, since failure of any element in the
The recovery algorithm that is outlined here deals with detection and recovery from the failure of signaling channels for IP endpoints. Such failures are due to connectivity outages between the server and the endpoint, which could be due to failure in the IP network or any other component between the endpoint and the server.
In the S8500 and
Endpoint ⇔ IP network ⇔
In this configuration, IP endpoints register to
