Reduced information scenario for Shared Segment Protection

This paper introduces a new implementation of Shared Segment Protection (SSP) in mesh communication networks, in which a novel Integer Linear Program (ILP) is proposed under a reduced amount of routing information. In particular, the scheme of Distributed Partial Information Management with Sufficient and Aggregated Information (DPIM-SAM) [1] will be adopted for trading the optimality with the reduction on the computation time. We will verify the ILP formulation by comparing its result with the cases of SSP and Path Shared Protection under the complete routing information scenario (SCI) in terms of performance and computation time.
