ROHC Tunneling Protocol for Source Specific Multicast Architecture

Abstract

Advances in IP-based multimedia applications, coupled with the evolution of wireless networks results in a need for effective multimedia transmission and delivery of real-time content such as voice and video streams. Multicast has the potential to optimize network performance and support scalable distributed applications without compromising performance, efficiency, and QoS but introduces new challenges to transmit multicast packet in the backbone especially when incorporated into wireless mesh network with limited bandwidth. We propose ROHC enabled tunnel for source specific multicast architecture that will compress packet header and aggregate them to together in a frame to save bandwidth and address the packet loss. Our ROHC enabled tunneling protocol will act as SSM channel (S, G) and is designed to be deployed in the backbone network. In this paper, we analyze and discuss the how to address the bandwidth efficiency and packet loss with respect to our proposed tunneling protocol.
