System and method to provide aggregated alarm indication signals

摘要

In an example embodiment, a method and system to provide aggregated alarm indication signals is provided. In example embodiments, an affected intermediate node detects a signal failure. A list of affected networks is determined, and a single aggregated alarm indication signal (AIS) message is generated per MEG level. The aggregated AIS message is then multicast to affected nodes. Instead of sending one AIS message per affected network, a single aggregated AIS message from the affected intermediate node may be generated and sent regardless of the number of affected networks.
