Paper Abstract:
|
Recently, the multipath transport protocol such as Multipath TCP becomes increasingly important. It allows more than one subflow TCP connections via different paths to compose one multipath connection. However, it has some problems when subflows are established with different delays. Especially, the limited buffer space at either sender or receiver may degrade the throughput due to head-of-line blocking. Although there are several studies focusing on the Multipath TCP under insufficient buffer size, they only use macroscopic performance metrics, such as average throughput, and they mainly focus on receiver side buffer. This paper shows the results of detailed microscopic analysis on how insufficient send/receive socket buffers give impacts on Multipath TCP throughput. The results indicate that insufficient send buffer reduces the throughput more than the receive buffer by introducing time gaps caused by retransmissions. |
