The SDN-based MPTCP-aware and MPQUIC-aware Transmission Control Model

This document aims to study and implement Multipath Transmission Control Protocol (MPTCP) and Multipath QUIC (MPQUIC) using application layer traffic optimization (ALTO) or Link Layer Discovery Protocol (LLDP) in Software-Defined Networking (SDN). In a traditional Software-Defined Networking, ALTO server collects network cost indicators (including link delay, number of paths, availability, network traffic, bandwidth and packet loss rate etc.), and the controller extracts MPTCP or MPQUIC packet header to allocate MPTCP or MPQUIC packet to suitable transmission path according to the network cost indicators by ALTO and YANG topology modules, which can reduce the probability of transmission path congestion and improving path utilization in a multipath transmission network.
