This paper considers the problem of service differentiation in an optical packet switched backbone. We propose and analyze a QoS routing approach based on different routing and congestion management strategies for different classes of service. Congestion resolution is achieved by using the wavelength and time domain and QoS differentiation in the single node is achieved by resource reservation in the wavelength domain. This is combined with alternate routing at the network level. In the paper we show that the proposed strategy guarantees very good performance to the high priority traffic with very limited impact on low priority traffic.

Abstract

This paper considers the problem of service differentiation in an optical packet switched backbone. We propose and analyze a QoS routing approach based on different routing and congestion management strategies for different classes of service. Congestion resolution is achieved by using the wavelength and time domain and QoS differentiation in the single node is achieved by resource reservation in the wavelength domain. This is combined with alternate routing at the network level. In the paper we show that the proposed strategy guarantees very good performance to the high priority traffic with very limited impact on low priority traffic.
