Abstract

The next-generation Internet should be based on high-capacity agile all-optical networks. A single-hop time-slotted all-optical packet-switched network is studied as a potential candidate for the ultra-high-speed next-generation all-optical metro network. This structure is composed of an all-optical wavelength-selective cross-connect core switch and a number of edge switches connected to the core switch in a star physical topology. Since optical packet switching (OPS) uses random medium access control, contention is the major problem for this network. Contention resolution techniques are used to resolve the contention. However, contention resolution hardware such as optical buffers and wavelength converters are expensive. In addition, optical buffers are complex and bulky. Therefore, we do not use contention resolution hardware in this network. Instead, we discuss and analyze the contention avoidance issue for such a network. Using more fibers and using additional wavelength channels to carry the same traffic are two schemes that can be used to reduce contention in OPS networks. We develop a cost model in order to optimize the number of fibers and additional channels required to achieve a given loss rate.
