Abstract: A routing modulation and spectrum allocation (RMSA) algorithm for elastic optical networks with a tradeoff between consumed resources and interval with boundary (Tradeoff-RnI) was proposed. For a connection, the amount of resources consumed (R) and the interval between the spectrum blocks and the boundary (I) are indicators that need to be minimised. For these two indicators, a new multi-objective optimisation model has been established. And then a linear combination αR+ (1 − α) I of R and I is designed. The target RMSA algorithm takes a compromise between R and I. The simulation results show that the Tradeoff-RnI algorithm has a much lower connection request blocking rate than the first-last fit algorithm and the block-assignment algorithm.
