Improving TCP Performance in Multipath Packet Forwarding Networks
Overview This paper investigates schemes to improve TCP performance in multipath forwarding networks. In multipath routing, packets to the same destination are sent to multiple next-hops in either packet-level or flow-level forwarding mode. Effective bandwidth is increased since one can utilize unused capacity of multiple paths to the destination. In packet-level multipath forwarding networks, TCP performance may not be enhanced due to frequent out-of-order segment arrivals at the receiver because of different delays among paths. To overcome this problem, the paper proposes simple TCP modifications. At the sender, the fast retransmission threshold is adjusted taking the number of paths into consideration.
