TL;DR

NetRawALM is a dynamic, decentralized application layer multicast protocol designed to improve delay, reliability, scalability, and traffic efficiency for multiparty video conferencing over IP networks.

Contribution

It introduces a network-based resource-aware multicast tree algorithm that addresses delay, reliability, heterogeneity, and traffic reduction in real-time multimedia applications.

Findings

Reduces average delay in multicast communication

Improves reliability and scalability for multiparty video conferencing

Reduces Internet traffic through LAN-aware architecture

Abstract

IP Multicast is one of the most absolute method for large bandwidth Internet applications such as video conference, IPTV, E-Learning and Telemedicine etc., But due to security and management reason IP Multicast is not enabled in Internet backbone routers. To achieve these challenges, lot of Application Layer Multicast (ALM) has been proposed. All the existing protocols such as NICE, ZIGZAG and OMNI are trying to reduce average delay by forming a Multicast tree. But still that problem has not been addressed fully. We are proposing a new protocol called NetRawALM, which will address the average delay, Reliability between nodes, Scalability of conference, Heterogeneity and resilient data distribution for real time multimedia applications by constructing the Network based Resource aware Multicast tree algorithm. This is very dynamic and decentralised. The proposed architecture is a LAN aware; it is used to reduce Internet Traffic.
