A system allowing for path monitoring and notification in a system of switching elements and processing elements is provided. An exemplary technique uses a monitoring and notification module configured to generate and output monitoring messages across multiple paths defined by the plurality of switching elements and the plurality of processing elements, detect a fault in the system based on the monitoring messages, and generate and output multiple alert messages across the multiple paths to initiate recovery from the fault As such, a single element (or group of elements) does not become isolated from the rest of the elements in the system.

Method and system for traffic flow and link management using domain notifications

A method and apparatus for fault analysis and fault isolation in a system of networked processors by using a central event correlation function and logical fault signature to provide for fault isolation of failed processing elements is presented. This central event correlation method uses asynchronous events from multiple input sources of same and different technologies and time-based fault correlation and ageing to match unique fault signatures and determine levels of fault recovery escalation over time. This mechanism uses an event driven recovery table to recognize a unique fault signature, count and age faults, provide fault threshold based recovery and generate events as needed to drive recovery escalation.
