GMNF-DVMRP: An enhanced version of distance vector multicast routing protocol

Abstract

In this paper we propose an enhancement to the Distance Vector Multicast Routing Protocol (DVMRP), called 'Group Membership Near First DVMRP' (GMNF-DVMRP), to decrease the network cost (NC) of the multicast tree formed by DVMRP. A simulation is implemented to compare our enhanced version and the original DVMRP. We find that our method saves about 5%-7% of NC of the multicast tree formed by DVMRP.
