Overview:

This paper presents a new analytical technique, based on the inclusion - exclusion principle from combinatorics, for the analysis of all-optical networks with no wavelength conversion and random wavelength assignment. The paper uses this technique to propose two models of low complexity for analysing networks with arbitrary topologies and traffic patterns. The first model improves the current technique by Birman in that the complexity of calculation is independent of hop-length and scales only with the capacity of the link as against that of which grows exponentially with hop-length. The paper then proposes a new heuristic to account for wavelength correlation and show that the second model is accurate even for sparse networks.
