Introduction
============
This project provides a C implementation (and a Python wrapper) for encoding/recoding/decoding of network coding. Random linear network coding (RLNC) [1] and several of its sparse variants are implemented. The library supports three catagories of sparse network codes (SNC): random codes, band codes and BATS-like codes [2].

The following decoders are implemented:

- (sub)generation-by-(sub)generation (GG) decoder has a linear-time complexity but exhibits higher decoding-induced overhead.

- overlap-aware (OA) decoder has optimized code overhead but exhibits higher complexity.

- band (BD) and compact band (CBD) decoders that apply to band code only.

- PP(perpetual) decoder applies to decode the window-wrapped codes only.

The library had been used for performance evaluation and comparison when authoring the following papers. If you find the lib useful, please cite the papers when appropriate.

Limitation
============
The library only supports coding against a given block of source packets, i.e., a *generation* of packets as termed in the network coding literature. Sliding-window mode is not supported.

A sliding-window implementation, also known as streaming coding, is available as a separate project at: https://github.com/yeliqseu/streamc, which implementes coding schemes proposed in
