Many-to-Many Traffic Grooming in WDM Networks

A large number of network applications today allow several users to interact together using the many-to-many service mode. In many-to-many communication, also referred to as group communication, a session consists of a group of users where each member transmits its traffic to all other members in the same group. In this paper, the authors address the problem of many-to-many traffic grooming in WDM mesh networks. In this problem, a set of many-to-many session requests, each with an arbitrary sub-wavelength traffic demand, are given and the objective is to provision the sessions on the WDM network with the minimum network cost.
