This talk seeks to illustrate the interplay between theoretical development and engineering implementation, with a personal slant. It centers on Network Coding (NC), a modern information theoretic development that leverages algebraic data manipulation during transport or storage in a network to enhance resource usage. It shows how practical considerations, such as rerouting in backbone networks, can lead to envisaging fundamental network information theory problems and how those, in turn, provide algorithmic solutions, that can be incorporated in common protocols used for data transmission. We particularly consider Random Linear Network Coding (RLNC), show its optimality for a broad set of fundamental problems and present its practical incorporation in the Transmission Control Protocol (TCP) generally used with the Internet Protocol (IP). We consider how recent developments in information theory, such as equivalence theory, that shows a separation between physical layer coding and network coding, may impact the design of sensor nodes. We conclude with open challenges and research directions driven by the coming convergence of data storage and networking. No background knowledge will be assumed.
