Throughput performance analysis of the multipath communication library MPT

Although the currently used mobile communication equipments (laptops, tablets, phones) usually have many network interfaces, the Internet communication technology uses only a single communication path for a connection. In this paper we would like to introduce a new architecture, which gives an easy-to-use extension for the current TCP/IP protocol stack and offers the possibility of using multiple paths for the communication, without rewriting the applications. The new architecture was implemented in Linux by a software tool named MPT. A laboratory environment was established for the throughput performance evaluation of the MPT based multipath communication. The measurement results show that the throughput capacity of the single paths can be efficiently aggregated by MPT.
