确定性网络研究综述
|
摘要
现有的互联网面对激增的视频流量和工业机器应用,存在着大量的拥塞崩溃、数据分组时延等问题,而许多网络应用,例如工业互联网、远程医疗、无人驾驶、VR游戏等,需要达到1～10 ms时延,微秒级抖动,但传统的网络只能将端到端的时延减少到几十毫秒。在这样的背景下,对网络端到端时延的控制如何从"尽力而为"到"准时、准确",成为当前全球关注的热点领域。通过介绍确定性网络的应用场景与需求,描述当前该领域的主要研究成果,总结分析了该领域的研究发展趋势和核心问题,期望对该领域的研究起到参考和帮助作用。
The current Internet faces a huge increase in video traffic and industrial machine applications, causing a lot of congestion and packet delays. Besides, many network applications, such as industrial Internet, telemedicine, driverless,VR games, etc, require a latency from 1 to 10 milliseconds and jitters within microsecond. But traditional network can only reduce the end-to-end latency to tens of milliseconds. Under this background, how to transit from "best effort" to"punctuality, accuracy", controlling the end-to-end delay has become a hot field of global network research. The application scenarios and requirements of the deterministic network were introduced,and the main research results of the current parties were described as well as the trend of development and core issues were summarized. It hopes to provide a reference and help for the research in this field.
