Abstract

With the rapid growth of cloud data, the internet of things, social media applications, high-end video streaming, etcWDM[3][3] is slowly becoming insufficient for all these future growths. The elastic optical network is slowly becoming the solution for these problems in the fiber-optic network.It can provide flexibility in the spectrum assignment and can even provide greater bandwidth. But with all these benefits come the problem of routing and spectrum allocation(RSA). In this problem, the frequency slots should be allocated to maintain continuity, contiguity, and nonoverlapping constraints. The paper explores the feasible way of solving the problem so that requests can be transferred through the network with minimum cost production.
