STOCHASTIC NETWORKS SEMINAR Speaker: Damon Wischik Date: Wednesday, October 3rd, 2001. Time: 3-4 p.m Location: Packard 204 Title: ISSUES IN MODELLING OPTICAL NETWORKS. Abstract: An all-optical network is likely to have two characteristics: high capacity, and limited flexibility. The high capacity comes about because optical switches are simple: they have no buffers and no high-speed per-packet classification, they just redirect beams of light. The limited flexibility comes about for the same reason; it has the consequence that neither packet-switched nor circuit-switched network models are entirely appropriate. In this talk I shall describe several possible models, which look at routing, multiplexing, and buffering.
