Abstract:
1. A method, comprising: receiving, by a server-layer node, a client-layer disjoint path request to provide a server-layer channel through a server-layer network, with the client-layer disjoint path request including 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; requesting and receiving by the server-layer node from a second server-layer node in the server-layer network route information of the current channel; determining, by the server-layer network, a particular channel through the server-layer network that is disjoint to the current channel based on said received route information of the current channel; signaling within the server-layer network to establish the particular channel; and subsequent to the particular channel being established, sending by the server-layer node one or more messages to the second server-layer node identification information concerning the particular channel.
