摘要

随着时延敏感型应用和超低时延场景的出现，低时延网络的研究受到了学术界、工业界和标准组织的广泛关注。了解时延产生的原因并设计相应的降低时延的技术使新兴应用的发展成为可能。首先按照网络的分层体系架构对时延来源进行分析，并以此为基础对降低时延的技术进行了综述。然后，针对数据中心网络、5G 以及边缘计算3种典型的低时延关键场景及优化时延的技术进行分析。最后，从网络架构革新、数据驱动优化时延算法及新协议设计3个方面展望了低时延网络发展面临的机遇与挑战。

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.
