Abstract
Forming of the Multicast tree with the best root considered as center selection problem (typically classified as NP-complete type). Alternatively called center Rendezvous Point (RP) due to the direct impact on the multicast routing protocol in terms of the performance. This research article introduces a new compound solution for multicast RP selection called Greedy based RP Selection Algorithm (GRPSA) to select the best RP for PIM-SM multicast routing protocol in IPv6 multicast domain based on Fitness or cost criteria supported by Dijkstra algorithm. The paperwork passes through two phases. First, MATLAB phase used for GRPSA implementation assisted by Fitness calculation to select the best RP called Native-RP. The second phase investigates the performance of GRPSA using QoS metrics compared to another candidate RPs. Validated using the GNS3 emulator for the core IPv6 multicast network and realized using UDP streaming data sourced from Jperf traffic generator via virtual machines at the network edges. The multicast technology implements a very high-efficiency point-to-multipoint data transmission over IP networks (IPv4 and IPv6). The results show GRPSA-RP performs better than other possible RPs by 25.2%, 25.3%, 46.2% and 62.9%, in terms of data received, bandwidth, jitter and loss respectively on average.
Highlights
The Rapid growth of Internet communications continues to create new services and network applications
The keynote that characterizes the current research is that it focuses on the fact, which says the output of any available Rendezvous Point (RP) selection algorithms would be one of the possible RPs within a multicast network under investigation
The first compare it to the optimally calculated RP selection, whereas the second should compare it to the average of all possible RPs
Summary
The Rapid growth of Internet communications continues to create new services and network applications. IP multicast available for both versions of Internet Protocols, IPv4 multicast and IPv6 multicast, but due to the low address space of IPv4 cannot provide the necessary support for multicast communication multicast (Bartczak and Zwierzykowski, 2012; Joseph and Mulugu, 2011). Multicasting is scalable across different sized networks but is suited to WAN environments. It enables people at different locations access to streaming data files, like a video, film or lives presentation without taking up excessive bandwidth or broadcasting the data to all users on the network.
