Abstract

Single-hop WDM networks based on a central passive star coupler (PSC) or arrayed-waveguide grating (AWG) hub have received a great deal of attention as promising solutions for the quickly increasing traffic in metropolitan and local area networks. These single-hop networks suffer from a single point of failure: if the central hub fails, then all network connectivity is lost. To address this single point of failure in an efficient manner, we propose a novel single-hop WDM network, the AWG∥PSC network. The AWG∥PSC network consists of an AWG in parallel with a PSC. The AWG and PSC provide heterogeneous protection for each other; the AWG∥PSC network remains functional when either the AWG or the PSC fails. If both AWG and PSC are functional, the AWG∥PSC network uniquely combines the respective strengths of the two devices. By means of analysis and verifying simulations we find that the throughput of the AWG∥PSC network is significantly larger than the total throughput obtained by combining the throughput of a st and -alone AWG network with the throughput of a st and -alone PSC network. We also find that the AWG∥PSC network gives over a wide operating range a better throughput-delay performance than a network consisting of either two load sharing PSCs in parallel or two load sharing AWGs in parallel.
