Multipath Congestion Control for Shared Bottleneck
نویسندگان
چکیده
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 same algorithm as TCP. We investigate a congestion control scheme that addresses this problem with the weighted congestion control approach. In our scheme, an end-to-end connection that uses flows along multiple paths can fairly compete with TCP flows at the shared bottleneck. Our scheme also maximizes the utilization of different path characteristics, such as bandwidth capacity and RTT. Our simulation results show that a bundle of multiple flows based on our scheme fairly competes with TCP flows at the shared bottleneck.

New congestion control algorithms are needed for multipath transport protocols such as Multipath TCP, as single path algorithms have a series of issues in the multipath context. One of the prominent problems is that running existing algorithms such as standard TCP independently on each path would give the multipath flow more than its fair share at a bottleneck link traversed by more than one of...
متن کاملImproving TCP-Friendliness for mHIP
Multihomed environments are getting increasingly common, especially for mobile users. mHIP was designed to provide secure multipath data transmission for the multihomed hosts and boost throughput of a single TCP connection by effectively distributing data over multiple available paths. In this paper we develop a TCP-friendly congestion control scheme for mHIP secure multipath scheduling solutio...
متن کاملTCP Fairness in Multipath Transport Protocols
Multipath transfers are a promising technique for enhancing the reliability of Internet connections, making better use of multihoming, and using spare network capacity. However, näıve designs and implementations of multipath transfer protocols risk substantial unfairness to well-behaved TCP flows. In this thesis, I propose two novel definitions of multipath TCP-fairness, and will show that mult...

Nowadays portable devices with multiple wireless interfaces and using multimedia services are becoming more popular on the Internet. This paper describes a family of multipath binomial congestion control algorithms for audio/video streaming, where a low variant of transmission rate is important. We extend the fluid model of binomial algorithms for single-path transmission to support the concurr...
