Abstract

We consider the problems of both static and dynamic resource allocation in spectrum flexible (flexi-grid) optical networks. We present algorithms for planning such networks given the requested demand rates. We also present dynamic spectrum allocation policies to serve time-varying traffic and analyze their blocking performance for the dynamic operation of a flexi-grid network.
