Abstract
A method, a node, and a network include mesh restoration and bandwidth allocation systems and methods for shared risk connection groups for source-based routing control planes. The mesh restoration and bandwidth allocation systems and methods utilize signaling from a node closest to a point of failure to “advise” source nodes about protect paths to be taken for a particular unidirectional or bidirectional connection in the event of mesh restoration. Specifically, the systems and methods include an ability to correlate connection information as Shared Risk Connection Groups (SRCG) to optimally utilize network bandwidth in the event of failure. The systems and methods could also be used to optimally distribute connections in a mesh network as well, trying to utilize maximum bandwidth, in distributed or centralized environments. Effectively, the systems and method distributed path computation in the network away from solely being the responsibility of source nodes.
