TRANSMISSION PERFORMANCE OF TRANSPARENT MULTI-WAVELENGTH OPTICAL CROSS-CONNECTED NETWORKS
The transmission performance of regular
two-connected multi-hop transparent optical networks in
uniform traffic under hot-potato, single-buffer deflection
routing schemes is presented. Manhattan Street (MS)
Network and ShuffleNet (SN) are compared in terms of
bit error rate (BER) and packet error rate (PER) both
analytically and by simulation. We implement a novel
strategy of analysis, in which the transmission performance
evaluation is linked to the traffic randomness of
the networks. Amplifier spontaneous emission (ASE)
noise, and device-induced crosstalk severely limit the
characteristics of the network, such as propagation distance,
sustainable traffic, and bit-rate. Our results indicate
that under the same load the BER performance of
single-buffer deflection routing is worse than hot-potato.
However, at BER=10-' single-buffer has a higher throughput
than hot-potato. It is shown that the feasibility
of deflection routing in transparent networks with MS
and SN topologies heavily depends on the power coupling
coefficient of the routing space switch used in each
node
