Goodput Improvement for MPTCP Based on Controlling the Difference of Delay
Yang Tao, Zhijun Yan · International Journal of Hybrid Information Technology · 2017
Due to the out of order problem, the goodput is usually far lower than the aggregated throughput.How to improve the goodput is a focus of researches.However, lots of them hardly consider the influence of the congestion window on out of order data.So, based on that, A goodput improvement solution based on controlling delay difference for the MPTCP (referred to as CDD-MPTCP) is put forward.By dynamically adjusting congestion window of each sub-streams, it can reduce end to end path delay, thus reducing out of order data.And, we also propose a data scheduling strategy based on the congestion degree of sub-streams to reduce the congestion during the transmission process.The NS-2 simulation results show that CDD-MPTCP can effectively decrease the amount of out of order data received at the receiver without loss of aggregate throughput.
