Abstract

A photonic packet switching device is designed for WDM based optical slotted ring networks which are suitable for B-ISDN access network and LAN/MAN. For the design, we devised a fiber optic delay line matched filter as a means of address filtering at the destination node and developed an efficient address decoding algorithm to accommodate the maximum available number of nodes in the ring network. Based on the algorithm, the maximum available number of node addresses in the ring is 3,432 for the case of 16-bit address. The design objectives of the photonic packet switching device are to eliminate the optical-to-electrical conversion at the address processing, to remove optical data from the ring at the destination nodes so that the slots can be reused a number of times in a rotation, and to be compatible with B-ISDN based on ATM concerning services, bit rate, interface, and switching node. The network architecture using the photonic packet switching device is also described. The simulation results show that the major part of the cell transfer delay in the network is coming from the propagation delay from a source to a destination. It was also observed that the average transfer delay characteristic of the network depends upon the aggregated transmission capacity of the network.
