Abstract

Our current world is revolutionned by the networks which are interconnecting any machine to any other one. Nowadays equipments are plugged to the network by the way of many different network adapters (Ethernet, wifi, GSM), and network equipments are more and more interconnected to each other creating a highly mesh network. Thus, redundant paths are created between any two endpoints enabling multipath or the use of multiple paths to handle a communication. The benefits of multipath are the enhancement of robustness against failure, and minimizing communication cost. In the present work, we will talk about some solutions of multipath applied to the transport level. We will expose the most important problem facing multipath which is packet reordering, and we will also expose results of our simulations.
