3. MPTCP protocol

3.1 Principles

The design of the MPTCP protocol is based on the fundamental principle that there are several possible and available paths for establishing communication between two terminals with several logical or physical interfaces. This principle does not necessarily imply that all the paths likely to support MPTCP communication are strictly disjoint, so that they can, for example, pass through the same network device (or even several).

Exploiting multiple paths using TCP alone would have been possible using an...
