Without proper receiving buffer assignment, Concurrent Multipath Transfer (CMT) could result in either not being able to achieve aggregate bandwidth or being a waste of memory resources. This paper analyses buffer requirement for CMT and find that receive buffer requirement is linearly correlated to ratio of round trip time of different path. Based on buffer requirement analysis, this paper proposes PAM, a precise receive buffer size assignment method. The simulation results verified the linear correlation and show that the PAM can effectively aggregate the bandwidth of multipath while making efficient use of memory resource.
