With the advances in switching technologies, ER switches are becoming popular since they perform better than EFCI switches. In the transitional period, the EFCI and ER switches may coexist in the same ATM network. Hence the eeciency of various ER schemes should be re-evaluated in the mixed EFCI-ER environment, not only in the homogeneous ER environment.(More)
The protocol independent multicast-sparse mode (PIM-SM) protocol establishes core-base tree to forward multicast datagrams in a network. In PIM-SM, the core or rendezvous point (RP) of a group is determined at each multicast router by hashing a group address, i.e. a class-D IP address, to one of the candidate RPs. The hash function is characterized by its(More)
SUMMARY This study investigates the problem of unfair-ness when QoS routing does not consider the mix of traffic classes. Unfairness is mainly caused by routing different traffic flows of the same class through paths with extremely different traffic mixtures , involving various service classes.
