Abstract

This paper introduces a mathematical model for supporting differentiated services availability in IP-over-WDM networks. IP traffic connections are allocated network resources based on their priority, data rate or network utility, which guarantee in turn the degree of service availability-quality-of-recovery (QoR) - of these connections when a failure occurs in a network. Using a Markov chain process, a mathematical model is conceived to quantify service availability which can be supported by M : N protection scheme, namely 1 : N protection scheme in IP-over-WDM networks. This model is analytically evaluated in terms of service availability and service disruption rate performance metrics.
