Reducing blocking probability in dynamic WDM networks using different schemes

We compare the performance of a dynamic WDM network for different blocking probability (BP) improvement strategies. First we analyze a strategy which effectively utilizes two Service Level Agreement (SLA) metrics i.e. holding-time combined with set-up delay tolerance, for connection provisioning. We investigate its performance improvement compared to the scheme proposed in [4] and with the strategy which exploits only the set-up delay tolerance for connection provisioning. Secondly, we evaluate the performance of the various approaches for network blocking reduction over a wide range of network loads. Our aim is to obtain an insight information, that can be useful for selection of an optimal strategy for designing a network, with specific network parameters and performance requirements.
