BER PERFORMANCE OF MULTIWAVELENGTH OPTICAL CROSS-CONNECTED NETWORKS WITH DEFLECTION ROUTING

The transmission performance of regular two-connected multihop transpa rent optical networks in uniform traffic under hot-potato, single-buff er deflection routing schemes is presented. Manhattan Street Network ( MS) and ShuffleNet (SN) are compared in terms of bit error rate (BER) and packet error rate (PER) both analytically and by simulation. The a uthors implement a novel strategy of analysis, in which the transmissi on performance evaluation is linked to the traffic randomness of the n etworks. Amplifier spontaneous emission (ASE) noise, and device-induce d crosstalk severely limit the characteristics of the network, such as propagation distance, sustainable traffic and bit rate. The results i ndicate that under the same load the BER performance of single-buffer deflection routing is worse than hot-potato. However, at BER = 10(-9) single-buffer has a higher throughout than hot-potato. It is shown tha t the feasibility of deflection routing in transparent networks with M S and SN topologies heavily depends on the power coupling coefficient of the routing space switch used in each node.
