linear network coding

Linear network coding is a method of transmitting data across a network where nodes combine multiple data streams using algebraic operations, typically addition and multiplication in a mathematical system called a field. Instead of just forwarding individual data packets, nodes create new, combined packets that carry information about multiple original packets simultaneously. This approach increases the efficiency and robustness of data transfer, allowing more information to be sent reliably over complex networks—like the internet—especially when parts of the network are unreliable or congested. In essence, it optimizes data flow by intelligently mixing information at intermediate points.
