Kodo is a flexible C++ network coding library, intended to be used for commercial applications and research on implementation of Network Coding. The library enables researchers to implement new codes and algorithms, perform simulations and benchmark the coding operations on any platform where a recent C++ compiler is available. The library provides a multitude of building blocks and parameters that can be combined to create codes. For convenience, several codes are predefined and high-level APIs are provided.
