Research on the transmission performance of QUIC in data center network

With the continuous development of emerging technologies such as big data, network application scenarios are becoming more abundant, which makes the network traffic grow rapidly, and the network scale of the data center is also expanding. In the current application of data center network is based on TCP protocol, but the traditional HTTP protocol over TCP has serious performance problems. Based on these, the new transmission protocol QUIC is developed by Google. QUIC not only reduces the delay, but also introduces the strict increasing sequence number mechanism in congestion control, multiplexing without queue head blocking. The performance of QUIC in the data center network also needs to be evaluated and researched. In this paper, QUIC is deployed in the data center network and QUIC-DCNsh is designed to accurately measure the performance of web transmission in QUIC protocol. The performance of QUIC under different bandwidth, delay and packet loss rate is researched.
