Abstract

Systems and methods providing resiliency between a server layer and a client layer include determining a minimal spanning tree in the client layer; determining a Steiner tree in the server layer based on vertices associated with the minimal spanning tree in the client layer; and determining one or more resiliency paths in the client layer based on the minimal spanning tree and the Steiner tree, wherein the one or more resiliency paths are added to the minimal spanning tree in the client layer based on potential failures in the Steiner tree. For example, the server layer is an optical layer and the client layer is a Time Division Multiplexing (TDM) layer.
