A method, apparatus and computer program product for utilizing network coding for multi-resolution multicast is presented. A network source partitions source content into a base layer and one or more refinement layers. The network source receives a respective one or more push-back messages from one or more network destination receivers, the push-back messages identifying the one or more refinement layers suited for each one of the one or more network destination receivers. The network source computes a network code involving the base layer and the one or more refinement layers for at least one of the one or more network destination receivers, and transmits the network code to the one or more network destination receivers in accordance with the push-back messages.

Network coding for multi-resolution multicast

Network-coding-enabled reliability architectures and techniques are provided that are capable of enhancing data transfer reliability and efficiency in next generation wireless networks. In some embodiments, the techniques and architectures utilize a flexible thread-based coding approach to implement network coding. The techniques and architectures may also, or alternatively, utilize systematic intra-session random linear network coding as a packet erasure code to support reliable data transfer.
