Dynamic routing of many-to-many traffic in WDM networks

Growing popularity of new network services including distributed computing, cloud computing, content delivery networks enforces implementation of new data delivery paradigms that can provide improvement in network performance. Therefore, in this paper we focus on many-to-many (m2m) traffic, that can be applied in computer networks to minimize resource consumption in group communication. We consider bandwidth demanding m2m applications, therefore we assume that the traffic is provisioned in optical layer using Wavelength Division Multiplexing (WDM) technology. We tackle dynamic Routing and Wavelength Assignment (RWA) problem with m2m traffic by designing effective algorithms. Moreover, we provide results of simulations showing performance of the proposed approach in terms of m2m session blocking probability.
