Abstract
We introduce a traffic model for circuit switched alloptical networks (AONs) which we then use to calculate the blocking probability along a path for networks with and without wavelength changers. We investigate the effects of path length, switch size, and interference length (the expected number of hops shared by two sessions which share at least one hop) on blocking probability and the ability of wavelength changers to improve performance. Our model correctly predicts unobvious qualitative behavior demonstrated in simulations by other authors. Keywords: All-Optical Networks, Wavelength Changers, Traffic Models 1 Introduction In an All-Optical Network (AON), the signals remain in the optical domain from the origin to the destination. We consider AONs supporting point-topoint sessions between users. Without wavelength changers, a session must use the same wavelength on every fiber. With wavelength changers, a session may use a different wavelength on each fiber it occupies. In eith...
