Özet

In order to sustain the connectivity in case of a technology related disaster, providing multipath connection infrastructure can be an alternative. Multipath TCP (MPTCP) is a transport layer protocol which allows more than one path to transfer TCP segments by utilizing multi-homed devices. MPTCP can be used for minimizing the connectivity problems in case of a failure. It is known that the performance of MPTCP can be increased if the paths for the subflows are carefully chosen by considering the disjointness and end-to-end delay of the paths. On the other hand, the scheduler affects the performance of MPTCP especially when connectivity problems exist. In this paper, we investigate the performances of different MPTCP schedulers and show how the selection of the paths for MPTCP subflows affect communication performance in case of link failures.
