NCAPQ: Network Coding-Aware Priority Queueing for UDP Flows Over COPE

In this paper, the authors compare the two mechanisms and they show that they achieve similar throughput benefits but work in complementary ways. They improve and combine them into a novel network coding-aware priority queuing scheme, which they refer to as NCAPQ. The proposed scheme improves throughput compared to COPE (by a factor of 10, in their simulations) and, even more importantly, compared to each individual scheme alone (by a factor of 2). Furthermore, they show that this significant increase in throughput comes without significant loss in fairness. The modifications they propose are minimal on top of COPE, thus making the scheme suitable for practical deployment.
