MPTCP Aggregation
André Perez · 2018
In multi-path transmission control protocol (MPTCP)-based aggregation solutions, aggregation occurs at the TCP layer. The target of MPTCP aggregation is to transmit data using multiple paths without causing modifications to existing infrastructures, such as the 4G mobile network, Wi-Fi access. The MPTCP connection consists of a combination of several TCP connections, with each TCP connection transmitted on a path to appear as a normal connection for the different devices crossed. For a normal TCP connection, congestion control introduces another limitation provided by the congestion window (cwnd). If during an MPTCP connection, a previously advertised address becomes invalid, then the affected host must advertise it in the REMOVE_ADDR option so that the other end can delete the TCP connections bound to that address. At the beginning of an MPTCP connection, it is important to ensure that the path is fully compatible with the MPTCP options.
