| Abstract | |
Spatial division multiplexing is a promising solution proposed for elastic optical networks to cope with the expected depletion of the capacity of single core networks. The introduction of space division multiplexing in optical networks brings new challenges for network protection since a lightpath can span high capacity and transmit data at different rates. In addition, there is a great need for protection mechanisms against failure due to the high volume of traffic carried in these networks. Moreover. these networks suffer from the fragmentation of the spectrum that hampers the contiguity and continuity constraints and therefore increase blocking. To address these problems, in this paper, we propose a protection algorithm for elastic optical networks with spatial division multiplexing using hybrid routing and FIPP p-cycle. The proposed algorithm prioritizes the use of single path routing, and uses multipath when no single path can be found to accommodate the requested bandwidth. The proposed algorithm is compared to four other algorithms that use single path routing. Results indicate that 100% protection for single failures with low overhead can be provided by the proposed algorithm. (AU) | |
