[summary]-SIGMETRICS'13: Tolerating Path Heterogeneity in Multipath TCP with Bounded Receive Buffers

Problem for current multipath delivering protocol: assume infinite receive buffer. When the buffer is limited, flow control will degrade the throughput a lot.

Contribution: the authors uses systematic coding, which saves receiving buffer. The basic idea :"send the redundancy at the beginning and transmit the uncoded packets
later so that the in-order arriving original packets could be released immediately and only the redundancy is buffered."

Additional benefit is the reduced coding complexity.
