Network coding is a technique where, the intermediate nodes of the network, instead of simply forwarding the information packets they receive, take several packets and combine them together in one packet for transmission. This can be used to obtain the maximum possible information flow in a network. Network coding is implemented in different scenarios; uni-casting, multi-casting and broadcasting. In multicast networks, network coding has proved to be better than the normal routing algorithms in different aspects as it increases the throughput and reduces the delay.
