Abstract: With the continuous emergence of emerging applications, more and more businesses require reliable transmission with low latency and low jitter. Especially in industrial scenarios, the number of access network devices has surged, and the network is developing towards large-scale and complex directions. How to ensure the deterministic delivery of key data streams has become a research focus. Deterministic network technology has received widespread attention due to its characteristics such as low latency, low jitter, low packet loss rate, deterministic bandwidth, and highly reliable transmission, and has good application prospects in fields such as automotive, energy, and industrial automation. The key technologies of deterministic networks are elaborated, the deterministic network fusion deployment solutions in two different scenarios are introduced, and finally the challenges faced by deterministic network technologies in practical application are analyzed.
Key words : deterministic networks;TSN;5G deterministic network;converged deployment

引言

2018~2023年思科年度互联网报告显示,到2023年,连接到IP网络的设备数量将是全球人口的三倍以上[1]。激增的数据流量带来了大量的网络拥塞、分组时延和传输抖动,同时,一些新兴应用如自动驾驶、远程医疗等对网络有着超低时延、超低抖动和超高可靠性的确定性通信要求,而传统网络提供的“尽力而为”服务已经无法满足其毫秒到微秒级别的应用需求,迫切需要建立起能够提供“准时、准确”服务的确定性网络传输体系。
