Enhanced Multipath QUIC Protocol with Lower Path Delay and Packet Loss Rate

Consider the high dynamics of traffic loading and resource provision on network hosts that forward data flows along a particular path between two endpoints. The Quick UDP Internet Connect (QUIC) protocol performs better than TCP for its effects in shortening the time of connection establishment and data transmission between two endpoints. Recent studies attempted to exploit the notion of multipath QUIC that forwards the data over multiple paths. Using the multipath QUIC can not only augment the total bandwidth capacity but also avoid traffic congestion on some paths. In this paper, our study proposes a novel multipath QUIC scheme which is able to minimize the flow completion time of multipath QUIC by jointly utilizing two measures of path delay and packet loss rate on a path. Experimental results show that the proposed algorithm is superior to other scheduling schemes, including naive QUIC and Lowest-RTT-First QUIC.
