Abstract
Research into high-capacity all-optical networking has produced a plethora of architectural proposals1 and has received added impetus from the activity surrounding the development of information superhighways. In this paper a novel proposal is made for the creation of a regular wavelength-routed re-configurable optical transport network (OTN), which could form the core network for a future U.K. National Information Infrastructure. This OTN is formed by embedding the regular structure into the fiber routes of the physical network. Network nodes consist of fiber-flexibility points, where fibers either can be connected to a wavelength-space switch, similar in concept to that being developed by the RACE R2028 project,2 or can be statically routed through the node in order to physically connect distant nodes. The two regular structures examined for this study were a 32-node hypercube and a torus, shown in Figs. 1(a) and 1(b), respectively.
