Approximation algorithms for the design of SDH/SONET networks

Abstract: In this paper, a graph partitioning problem that arises in the design of SONET/SDH networks is defined and formalized. Approximation algorithms with performance guarantees are presented. To solve this problem efficiently in practice, fast greedy algorithms and a tabu-search method are proposed and analyzed by means of an experimental study.

“…A graph partitioning formulation has been used to develop approximation algorithms [2,6] for this problem. In this formulation, a simple undirected graph G(V , E), called the traffic graph, is constructed to represent the set R of unitary duplex traffic demands, where the node set V (G) denotes the set of network nodes in the UPSR.…”

“…For a traffic graph G, their algorithm uses at most (1 + wavelengths, which is twice the minimum. Brauner et al [2] also proposed an approximation algorithm for the k-edge-partitioning problem. Their algorithm grooms traffic demands into the minimum number…”
