Although an AWG-based single-hop WDM network is a desirable architecture to realize an all-optical packet network in MAN, scalability is a problem. This problem can be solved by providing optical couplers between the AWG and other nodes and collecting multiple nodes. In this case, packet collisions at couplers will seriously increase the packet delay. So, the author proposed to install an autonomic packet collision avoidance mechanism in couplers. The installation of active devices at couplers degrades the network reliability. So, we need to improve the reliability by providing a backup plane when applying it to MAN. However, simply doubling all the couplers will largely increase the CAPEX. The probability that multiple collision avoidance mechanisms break down simultaneously is really small, so in this paper, we propose to construct the backup plane by sharing couplers among nodes accommodated in different couplers on the normal plane. |
