An architecture of IPTV networks based on network coding

Abstract

In this paper, we propose a novel architecture for IPTV networks, where network coding is deployed in the backbone networks. As the number of subscribers to IPTV services increases, the size of backbone network is correspondingly grows. Therefore, it is challenging to manage network faults in a centralized manner. Moreover, IPTV services that provide larger video stream sizes in a limited network capacity becomes a problem of current networks. In order to overcome such challenges of IPTV services in the current networks, we propose to deploy network coding technique, which can increase network capacity while improving robustness against network faults.
