摘要

提出了一种适用于大规模网络部署的3层转发技术——LDN（large-scale deterministic network），在保留传统IP转发技术统计复用的优势基础之上，LDN技术可实现对端到端时延上界及抖动上界的严格保证，为5G uRLLC（ultra-reliable low-latency communication）切片、工业互联网等未来应用场景提供网络服务支持。通过仿真实验对比了在相同网络环境下，传统IP及确定性IP在端到端最差时延及抖动上的差异，证明了LDN技术的有效性。

Abstract

A layer 3 forwarding technology LDN (large-scale deterministic network) which was scalable for wide area deployment was proposed.LDN not only keeps the advantage of traditional IP’s statistic multiplexing

but also be able to guarantee end-to-end bounded latency and bounded jitter required by 5G uRLLC (ultra-reliable low-latency communication) slice

industrial network

and other future scenarios.A simulation experiment was taken between traditional IP and deterministic IP (LDN enabled) on end-to-end worst case latency and delay variance (i.e.

jitter)

the comparison results successfully proved the effective and efficient of LDN technology.
