Multicast fault recovery on network coding
Xinmei Wang · Journal of Xidian University · 2007
Problems on link failure recoveries in multicast networks are considered.From the idea of erasure codes,a way to construct a reliable multicast system based on network coding is presented.When limited link failures have occurred in the network,we can have a recover-based solution for all recoverable failures with a static network code,and do not need to change the coding of interior nodes.Based on the information flow decomposition,a way to construct the network codes in a smaller field is proposed.In this way,we can provide nearly instantaneous self-healing multicast communication networks to enhance the robustness of the multicast connections,and achieve a higher rate of multicasting with less required network capacity.
