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： Systems and methods for fast restoration in a network using a control plane include detecting a failure on a link associated with the node; and providing failure information through in-band data path overhead of an affected connection, wherein the in-band data path overhead is sent over a fast path, wherein the failure information is received at an originating node of the affected connection via the fast path, prior to the originating node receiving control plane signaling via a slow path relative to the fast path.

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.
