Although coding over P2P is effective in some ways, coding at routers can bring us more significant benefits. Unfortunately, routers in todaypsilas network are mostly not capable of network coding. We propose a novel scheme to equip routers with coding functionalities. To do this, we design a routing protocol based on network coding and regulate the coding functionalities at routers. Simulation results show that for content distributions in single-source and multiple-sink networks, our scheme exhibits better performance in terms of download time and balanced load.
