This paper considers an optical packet switching (OPS) network subject to asynchronous, variable-length packets and connection-oriented operation. The problem of providing QoS in such a scenario has been widely discussed and several solutions have been provided. They mainly suggest the use of some form of resources reservation on top of the contention resolution algorithm in order to isolate the higher priority traffic from the lower one. Recently we propose the novel technique called SCWS and evaluated it in a single node scenario. SCWS consists of implementing different contention resolution algorithms, each one specifically designed to cope with the requirements of a given priority traffic. In this paper we analyze the performance results when applying SCWS technique in a network scenario. Obtained results highlight the merits of such technique.

Abstract

This paper considers an optical packet switching (OPS) network subject to asynchronous, variable-length packets and connection-oriented operation. The problem of providing QoS in such a scenario has been widely discussed and several solutions have been provided. They mainly suggest the use of some form of resources reservation on top of the contention resolution algorithm in order to isolate the higher priority traffic from the lower one. Recently we propose the novel technique called SCWS and evaluated it in a single node scenario. SCWS consists of implementing different contention resolution algorithms, each one specifically designed to cope with the requirements of a given priority traffic. In this paper we analyze the performance results when applying SCWS technique in a network scenario. Obtained results highlight the merits of such technique.
