摘要: 近年來,時間敏感網絡技術(TSN)的發展逐步引起工業界的廣泛關注,其憑借低抖動、低延時、確定性傳輸等優勢,為對傳輸時延有較高要求的應用場景提供了有力支撐,成為下一代工業網絡承載技術的重要演進方向之一。為了在端到端的層面上滿足某些垂直行業業務對低時延、高可靠的需求,5G網絡在R15 URLLC的基礎上對QOS、空口同步、頭壓縮等方面進行了增強,以滿足TSN網絡對于5G設備的嚴苛要求。首先從垂直行業需求入手,分析了5G網絡與TSN融合的必要性,最后結合3GPP R16標準進展研究了TSN對于5G商用網絡改造需求以及面臨的挑戰。

Abstract: Recent years, the development of Time Sensitive Network(TSN) technology has gradually attracted widespread attention from industry. Characterized by low jitter, low delay and deterministic transmission, TSN has provided strong support for scenarios with high requirements of transmission delay. It has become one of the important evolution directions of the next-generation industrial network bearer technology. In order to meet the low-latency and high-reliability requirements of vertical industry services at the end-to-end level, 5G network has enhanced QoS, air interface synchronization, header compression and other aspects to meet the strict requirements of TSN network for 5G equipment on the basis of R15 URLLC. Starting from the demands of vertical industries, this article analyzes the necessity of the integration of TSN and 5G network. The needs and challenges of TSN for 5G commercial network transformation has also been studied based on the 3GPP R16 standardization progress in the end.
