The TCP has been in use since the seventies and has later become the predominant protocol of the internet for reliable data transfer.Numerous TCP versions has seen the light of day (e.g.TCP Cubic, Highspeed, Illinois, Reno, Scalable, Vegas, Veno, etc.), which in effect differ from each other in the algorithms used for detecting network congestion.On the other hand, the development of multipath communication technologies is one today's relevant research fields.What better proof of this, than that of the MPTCP (Multipath TCP) being integrated into multiple operating systems shortly after its standardization.The MPTCP proves to be very effective for multipath TCP-based data transfer; however, its main drawback is the lack of support for multipath communication over UDP, which can be important when forwarding multimedia traffic.The MPT-GRE software developed at the Faculty of Informatics, University of Debrecen, supports operation over both transfer protocols.In this paper, we examine the effects of different TCP congestion control mechanisms on the MPTCP and the MPT-GRE multipath communication technologies.
