A Peer-to-Peer Overlay Network for Real Time Video Communication using Multiple Paths

This paper presents a peer-to-peer (P2P) service for the transmission of real-time video content, exploiting the contemporary usage of multiple network paths over the current Internet. Before starting the transmission, the sender probes the available paths for their Round Trip Time and other parameters using simple ICMP packets. Then it chooses the set of paths to be used in order to maximize the expected Signal to Noise Ratio (SNR) while meeting the delay requirements of the streaming content. The video is encoded using a Multiple Description Coding (MDC) technique. Simulations show that the proposed algorithm always chooses one of the group of paths that yields the best SNR.
