This paper describes an analytical model for a 3-level quality of service scheduling in hybrid optical networks. Three service profiles with different requirements are considered, namely: guaranteed transparent service, where packets are transparently forwarded into pre-established paths; real-time statistically multiplexed packet service, where real-time packets are forwarded with limited delay; best-effort packet service, which is a typical best-effort service like IP traffic in the Internet. The model captures the loss of real-time and throughput of best-effort packet traffic, in asynchronous context, when considering best-effort traffic saturating the channels of a link. The accuracy of the model is evaluated by validating it against simulation, proving how the model provides excellent results and captures very well the behavior of both classes of traffic.

Abstract

This paper describes an analytical model for a 3-level quality of service scheduling in hybrid optical networks. Three service profiles with different requirements are considered, namely: guaranteed transparent service, where packets are transparently forwarded into pre-established paths; real-time statistically multiplexed packet service, where real-time packets are forwarded with limited delay; best-effort packet service, which is a typical best-effort service like IP traffic in the Internet. The model captures the loss of real-time and throughput of best-effort packet traffic, in asynchronous context, when considering best-effort traffic saturating the channels of a link. The accuracy of the model is evaluated by validating it against simulation, proving how the model provides excellent results and captures very well the behavior of both classes of traffic.
