MPTCP Congestion Control Algorithms for Streaming Applications – Performance Evaluation in Public Networks

Abstract

Efficient data transfer for high-quality streaming requires fast speed, low latency, and stable transmission parameters. Utilizing multiple communication paths is a promising solution for improving performance. This paper evaluates the most common MPTCP congestion control algorithms in the context of streaming applications in the open Internet. The results show that the BALIA algorithm is the most effective CC algorithm for multi-path streaming. This algorithm achieves the lowest path delay and Head-of-Line blocking degree with consistent throughput. Conversely, the MPTCP CC algorithm wVegas exhibits the weakest performance.
