Out-of-Order Transmission for In-Order Arrival Scheduling for Multipath TCP

MPTCP exploits using a device´s multiple interfaces to achieve higher end-to-end throughput and increased robustness during times of path failure. We consider potential delay advantages that MPTCP can provide users of real-time applications (e.g, online gaming) where higher throughput does not necessarily guarantee a higher quality experience. We first explain a situation where jitter can occur in an MPTCP data transfer even when underlying network paths are stable. We propose a new scheduling policy that mitigates jitter by transmitting packets out-of-order on different sub flows such that they arrive in-order at the MPTCP receiver.
