Abstract
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.
Claims22
A system comprising:
- a plurality of switching elements connected over a plurality of paths;
- a plurality of processing elements, a processing element of the plurality of processing elements connected to at least one of the plurality of switching elements;
- and
- a monitoring and notification module configured to:
- generate and output monitoring messages across the plurality of paths;
- detect a fault in the system based on the monitoring messages;
- determine that the fault is due to a switching element failure;
- and generate and output alert messages across the plurality of paths to trigger the plurality of processing elements to perform recovery from the fault;
- wherein the plurality of processing elements are configured to selectively switch operation to a port side that is unaffected by the switching element failure based on the alert messages without controlling the plurality of switching elements.
A method implemented in a network having a plurality of switching elements and a plurality of processing elements, the method comprising:
- generating and outputting monitoring messages across a plurality of paths in the network;
- detecting a fault in the network based on the monitoring messages;
- determine that the fault is due to a switching element failure;
- generating and outputting alert messages across the plurality of paths to trigger at least one of the plurality of processing elements to perform recovery from the fault;
- and
- the plurality of processing elements selectively switching operation to a port side that is unaffected by the switching element failure based on the alert messages without controlling the plurality of switching elements.
A system comprising:
- a plurality of switching elements connected over a plurality of paths;
- a monitoring and notification module configured to:
- generate and output monitoring messages across the plurality of paths;
- detect a fault in the system based on the monitoring messages;
- determine that the fault is due to one of a shelf interconnection failure and a switch cross-connection failure;
- and
- generate and output alert messages across the plurality of paths;
- and
- a plurality of processing elements configured to perform a local port Internet protocol (IP) address recovery based on the alert messages.
A method implemented in a network having a plurality of switching elements interconnected with a plurality of processing elements, the method comprising:
- generating and outputting monitoring messages across a plurality of paths in the network;
- detecting a fault in the network based on the monitoring messages;
- determining that the fault is due to one of a cross-connection failure and a shelf interconnection failure;
- generating and outputting alert messages across the plurality of paths to trigger the plurality of processing elements to perform recovery from the fault;
- and
- the plurality of processing elements performing a local port Internet protocol (IP) address recovery based on the alert messages.
