Abstract : In this paper we present the design of a RWA protocol for larger WDM network (RPLN), consisting of 'N' sector networks, each with a centralized management system (CMS). A backup central CMS of high capacity is maintained to share the work and to takeover if any of the sector CMS fails. As per the connection request, the central CMS decides inter or intra sector transmission. In the case of intra transmission, the sector CMS identifies the optimal lightpaths based on number of free wavelength and distance. For inter transmission, it acts as a node for the central CMS. The central CMS acts as the backup CMS if anyone of the sector CMS fails. By this we introduce a new concept of centralized-centralized-distributed. RPLN overcomes the single point failure and performance bottleneck of a large network with single CMS. Furthermore grooming is also used to improve the blocking probability of connection requests. © 2012 Springer-Verlag.
