MPTCP: How Can Route Diversity Improve the Internet Traffic? 93 MPTCP: How Can Route Diversity Improve the Internet Traffic?

This contribution aims to provide the fundamen-tal basis of a new Transmission Control Proto-col (TCP) designed for the next generation Internet. The TCP protocol is not capable to carry out all the growing traffic generated by the Internet as it leads to congestion and packet loss out of the quality of service specially required for critical connections. Moreover this behavior is accentuated in heavy load conditions. The Internet traffic becomes bursty and this trend is amplified as more participants contribute to generate data connections on a shared complex infrastructure. Therefore we focus on the design of a new protocol that aims to avoid or partially reduce the congestion appearance and the high variability of the Internet traffic. The stationarity of connection paths met on the Internet are judged responsible of the emergence of these characteristics. As a consequence a TCP-like protocol based on Multiple Paths (MPTCP) is suggested for a data transmission between two net-work entities in order to improve the QoS of the defined connection. We propose there several algo-rithms that aim to extract multiple routes between two network components. This work is based on a theoretical modeling supported by simulations. Our network simulator is developed on top of the Scilab environment
