Practical Implementations of Network Coding

Overview

This course introduces the students to the challenges and approaches of the state-of-the-art implementations of network coding. The course is taught not just through lectures but also with hands-on exercises using the Kodo software library. Kodo is available as a C++ and Python library and web tool. Therefore, students with different programming preferences will be able to approach it.

The initial lectures refresh the knowledge of the students of the theoretical background of network coding, e.g., the min-cut max-flow of a network, inter-flow network coding, and intra-flow Random Linear Network Coding (RLNC). The student is then introduced to the state-of-the-art software library Kodo and the advanced implementations of network coding such as systematic, sparse, tunable sparse, sliding window, etc. The course also covers the benefits of network coding in distributed storage applications. By the end of the course, the student will be introduced to advanced applications of network coding, e.g., Coded TCP, MORE, FULCRUM.

The exercises will teach the students how to use sockets in python as well as the python bindings of the Kodo software library for implementing unicast and broadcast communication applications.

• QUIC is a transport protocol originally designed, implemented and deployed by Google that is being standardized at the IETF, and it is used nowadays by many servers in the world and supported by several web browsers. Its first stable specification will bring the same functionality as TCP+TLS+HTTP/2. In this article, the authors add Forward Error Correction (FEC) codes to the protocol and show their results.
