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, in a network element, for detecting and propagating resizability information of an Optical channel Data Unit flex (ODUflex) connection includes receiving resizability information in overhead associated with the ODUflex connection, wherein the resizability information indicates a number of available tributary slots and whether the ODUflex connection is symmetric; and adjusting the resizability information based on a change in the available tributary slots due to a bandwidth change at the network element. The systems and methods include a solution to communicate, in real time, the resizability information of an ODUflex connection utilizing the associated data path to carry it instead of the management/control plane.

摘要： A framework is disclosed which enables a management system to manage completely different type of network elements (NEs) running different versions of their embedded software by introducing generic operational interfaces, generic data interfaces, information descriptors and self adaptive control mechanism. This Management system framework consists of mainly two parts a) core application and b) element-dependent components and c) a set of generic interfaces. When the management system is launched, it executes the core application. The core application comprises of network element independent version independent generic functionalities that can be used to interact with a variety of network elements and a dynamic control mechanism to make selection and placement of pluggable components at appropriate time and place during execution. After the core application is executed, whenever a need to manage one or more network elements, self adaptive control mechanism will take decision based on information descriptor of that target NE and NE type dependent version dependent modules are incorporated or “plugged in” with core application to produce an overall management mechanism to manage that target NE.

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.
