Low-latency networking:architecture,key scenarios and research prospect

Abstract

With the advent of delay-sensitive applications and ultra-low latency scenarios,research on low-latency networking is attracting attention from academia,industry,and standards organizations.Understanding the causes of latency and designing corresponding techniques to reduce latency enable the development of emerging applications.The sources of latency according to the layered architecture of the network was analyzed,and summarizes the techniques for reducing the latency.After that,three typical low-latency key scenarios and delay optimization techniques for data center network,5G and edge computing was analyzed.Finally,the opportunities and challenges that may be encountered in the development of low latency networks were presented from the perspectives of network architecture innovation,data-driven latency optimization algorithm and the design of new protocols.
