In this paper we tackle the problem of online resource allocation in dynamic flex-grid optical
networks. To meet the stringent connection setup times envisioned for bandwidth-on …

In this paper we propose an online, reward-based routing and spectrum assignment (RSA)
method for multirate flex-grid optical networks. The method, denoted as MDP-RSA, is …

In this paper we propose a novel method for online connection admission and grade of
service control in flex-grid optical networks, which aims at maximizing a definable reward …

The efficient allocation of network resources is key to the overall performance and the quality
of services provided. Thanks to their high data rates, optical networks are the cornerstone of …

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 …

Dynamic optical networks hold the potential of satisfying very large bandwidth requirements
of many of the grid applications. However, encapsulation of optical network elements into …

Abstract A novel Class-Based First Fit (CBFF) spectrum allocation policy is proposed for
dynamic flexgrid optical networks. The effectiveness of the proposed CBFF policy is …
