GMNF-DVMRP: A modified version of Distance Vector Multicast Routing Protocol

Abstract

In this paper, we make a survey of Distance Vector Multicast Routing Protocol (DVMRP) and find that it is not optimal in the aspect of network cost (NC). Therefore, we propose a modified version of DVMRP, called ''Group Membership Near First-DVMRP'' (GMNF-DVMRP), to decrease the NC of the multicast tree formed by DVMRP. A simulation is implemented to compare our modified version and the original DVMRP. We find that our method save about 5-7 percent of NC of the multicast tree formed by DVMRP.
