Abstract :
Multi-homed devices equipped with multiple network interfaces can transmit data over multiple access paths simultaneously for high-speed services. One major problem is that the utilization of different paths with diverse delays may cause packet reordering among packets of the same flow. In the case of TCP-like, the reordering exacerbates the problem by bringing more timeouts and unnecessary retransmissions, which eventually degrades the throughput of connections considerably. To address this issue, we propose a Sender-based Multipath Out-of-order Scheduling (SMOS) scheme, which exploits the sending time discrepancy to preserve the in-order packet arrival. The performance of the proposed SMOS is investigated and compared against other schemes. The obtained results demonstrate the outstanding performance of SMOS as it enhances the utilization of aggregate bandwidth while decreasing the probability of triggering 3 dupACKs.
