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年思科年度互聯(lián)網(wǎng)報(bào)告顯示，到2023年，連接到IP網(wǎng)絡(luò)的設(shè)備數(shù)量將是全球人口的三倍以上[1]。激增的數(shù)據(jù)流量帶來了大量的網(wǎng)絡(luò)擁塞、分組時(shí)延和傳輸抖動，同時(shí)，一些新興應(yīng)用如自動駕駛、遠(yuǎn)程醫(yī)療等對網(wǎng)絡(luò)有著超低時(shí)延、超低抖動和超高可靠性的確定性通信要求，而傳統(tǒng)網(wǎng)絡(luò)提供的“盡力而為”服務(wù)已經(jīng)無法滿足其毫秒到微秒級別的應(yīng)用需求，迫切需要建立起能夠提供“準(zhǔn)時(shí)、準(zhǔn)確”服務(wù)的確定性網(wǎng)絡(luò)傳輸體系。
