Abstract
In one embodiment, a network server layer provides disjoint channels in response to client-layer disjoint path requests. For example, the network layer can be an optical network, and the client layer may be a packet switching layer (e.g., label switching, Internet Protocol). In one embodiment, a server-layer node receives a client-layer disjoint path request to provide a server-layer channel through a server-layer network. The client-layer disjoint path request includes an identifier corresponding to an existing client-layer path that traverses a current channel through the server-layer network that does not include the server-layer node. The server-layer network determines a particular channel through the server-layer network that is disjoint to the current channel based on route information of the current channel, and then signaling is performed within the server-layer network to establish the particular channel.
