DCQUIC: Flexible and Reliable Software-defined Data Center Transport

Numerous innovations based on the data center TCP support the rapid development of data center. However, with changes in topology, scale and traffic patterns, the new requirements of data center on transport protocol are more agile and more reliable. Improving transport performance by patching TCP seems to be facing a bottleneck. We explored the possibility of applying QUIC inside the datacenter networking. This paper proposes a new data center transport scheme based on QUIC, called data center QUIC (DCQUIC). We especially proposed an proactive connection migration mechanism suitable for datacenter networking. Like the efficiency of UDP and the reliability of TCP, DCQUIC exhibits exciting performance and scalability, and may become a potential transport technology to support the development and innovation of data centers in the future.
