This contribution aims to provide the fundamental basis of a new Transmission Control Protocol (TCP) designed for the next generation Internet. The TCP protocol is not capable to carry out all the growing tra‐c 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 tra‐c becomes bursty and this trend is amplifled 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 tra‐c. The stationarity of connection paths met on the Internet are judged responsible of the emergence of these characteristics. As a consequence a TCPlike protocol based on Multiple Paths (MPTCP) is suggested for a data transmission between two network entities in order to improve the QoS of the deflned connection. We propose there several algorithms 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.
