Network coding has been used for error control in communication over lossy channels. However, there do not exist congestion control mechanisms in the literature that are specifically tailored for these coding techniques. In this talk, I will present Trickle, a lightweight and practical framework that is customized to meet the needs of coding. Trickle is designed based on the principle of back pressure, and maintains a novel triple-node indexed queueing structure at each node. As compared to existing back pressure protocols with per-destination or per-link queues, Trickle uses significantly fewer queues, and is more scalable to large networks. Our experimental results have shown that Trickle achieves much higher throughput than existing schemes.
