Abstract
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 used the behavior of this protocol is consistent in situation of adding new sub-flow or removing flow on a faulty line. Different strategies for path selection are possible with great impact on Multipath TCP session performance. Network structure consisting of few connections with similar parameters is optimal for full mesh Multipath TCP path topology. In this case the behavior of Multipath TCP predictable.
Highlights
Despite the fact that the world of communications is rapidly changing the TCP is still main protocol for Internet communication today
In the new era of modern communications, we find Multipath TCP very promising
At first we introduce Multipath TCP protocol and its specific implementation
Summary
Despite the fact that the world of communications is rapidly changing the TCP is still main protocol for Internet communication today. It is well designed and very reliable, and major applications all over the world depend on them. There is a great increase in a number of devices connected to Internet nowadays and what is more important these devices typically have more than one active interface connected to Internet network at a time. With decreasing price for mobile broadband data and increasing FUP (Fair User Policy) limits it obvious that there are new possibilities to improve connection stability and network throughput by utilizing multiple interfaces at a time. It is necessary to increase throughput and preserve fairness among data flows in
