Abstract: The capability of multicasting is an important feature in data networking and is emerging in to a highly demanded service being offered by all major ISPs (Internet Service Providers). The benefits of multicast include reducing the overhead in transmission on the network and sender and reducing data delivery delay for all destinations. Multicast (Point-to-multipoint) refers a communication pattern in which a source node sends a message to a group of destination nodes. The major advantage of multicasting is to decrease the network load. On another hand, multicasting can be very useful in resource discovery. Quality of Services (QoS) is required for most of the multicast application and thus, the constraints for QoS provisioning should be also considered. In this paper we present the analysis and simulation of the performance of existing Dense mode and CBT mode multicast routing algorithms. Therefore, the performance comparison of existing multicast routing protocols over wired mesh networks are essential in order to analyze their behavior effectiveness.
