摘要： A method for establishing an alternate pathway to an endpoint that may determine that a network connection is lost between a first network element and an application server. The method may select a second network element from a virtual network operating on an optical network. The second network element may include a network connection over the optical network to the application server, and a network connection to the first network element over the virtual network. The method may designate the second network element to act as a network proxy to the first network element. The first network element may use the second network element as the network proxy for receiving data over the virtual network. The method may receive data from the application server at the first network element using the second network element as the network proxy.

摘要： 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.
