Data Path Selection for Multipath TCP Considering RTT
نویسندگان
چکیده
Multipath TCP (MPTCP), which is based on TCP, transports data through multiple network interfaces at the same time. It is well known that MPTCP shows better throughput than legacy single path TCP. However, we argue that single path TCP may be better than MPTCP in terms of the flow completion time when delays of paths are significantly different. To avoid this problem, we propose an efficient packet transmission scheme for MPTCP to determine whether a newly connected long-delay subflow is used for transporting data. If the long-delay subflow is not beneficial to the flow completion time, it is not used.

Evaluating Multipath TCP Resilience against Link Failures
Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...
متن کاملCombined Multipath Routing and Congestion Control: a Robust Internet Architecture
Network management is complicated by uncertain traffic patterns and workloads. Flexible routing schemes mitigate some of the problems by making the exact location of capacity less important: if there is available capacity the routing scheme will find it. In this paper we propose a combined multipath routing and congestion control architecture that gives performance improvements to the end user ...

متن کاملMultipath Congestion Control for Shared Bottleneck
Multipath transport protocols, which transmit data over multiple distinct paths in an end-to-end connection are introduced. However, they have a problem in terms of fairness. When the transmissions along several paths share the same bottleneck link, the multipath connection receives higher throughput than a competing regular TCP flow, because it executes congestion control per path with the sam...

The results of experiments with Multipath TCP (Multipath Transmission Control Protocol) in LTE (3GPP Long Term Evolution) networks are presented. Our results show increased resiliency and availability of network Multipath TCP connection. Using multiple sub-flows over diverse network paths inside Multipath TCP session results in greatly increased bandwidth and availability. When Multipath TCP is...
