โœฆ Synopsis

It is shown that a Partitioned Optical Passive Stars (POPS) network with g groups and d processors per group can route any permutation among the n ยผ dg processors in one slot when d ยผ 1 and 2Jd=gn slots when d41: The number of slots used is optimal in the worst case, and is at most the double of the optimum for all permutations p such that pรฐiรžai; for all i:

This paper is concerned with optimal transmission schedules in the TWDM (time and wavelength division multiplexed) optical passive star network. Our model of the network consists of a set V of N nodes with N tunable transmitters and N fixed-tuned receivers (where each node is assigned a transmitter-

Optical networks employing wavelength division multiplexing (WDM) and wavelength routing are a potential candidate for future widearea networks. As these networks are prone to component failures and they carry a large volume of trafยฎc, providing fault tolerance capability to them is an important iss
