Modified Transfer Mechanism over Multipath TCP

With the presence multipath transport protocols (mptcp), a host can shift some of its traffic from more congested paths to less congested ones. Doing so it can compensate for lost bandwidth on some paths by moderately increasing transmission rates on other routes. But existing multipath proposals concentrate on a rough estimate of network congestion using packet losses, which is not so efficient. This project mainly focuses on multipath congestion control and proposes a modified mechanism for packet data transfer which is based on the packet queuing delay as congestion signals and thus achieves a good performance.
