摘要

时间敏感网络（TSN）和确定性网络（DetNet）是确定性网络整体解决方案的重要组成部分，目前产业界还缺少这两种技术在大规模联合组网方面的研究。在 OMNeT++仿真平台基于时隙调度实现了 TSN 和DetNet 联合组网的确定性转发，并打通了控制器和仿真系统的通道，实现了转控协同的确定性仿真网络。重点介绍了对于仿真系统的改造，以及基于此的大规模跨域场景下确定性业务的端到端时延和抖动性能研究。结果表明，在大规模跨域场景下，时隙调度的机制可以提供端到端的确定性业务保障。

Abstract

TSN and DetNet are major components of the deterministic networking solution

detailed research has been conducted by industry and academia.However

the study seldom considers the joint of these two technologies under large-scale networks.To facilitate the analysis of the joint networks

TSN and DetNet specifific extensions to the popular OMNeT++/INET framework for network simulations was presented

in particular

the time slot scheduling

the TSN node/host/interface and DetNet node/host/interface

the framework for collaboration between the controller and the simulation system.A proof of concept implementation and exemplary evaluation of the joint of these two technologies under large-scale networks was presented.The results show that in large-scale cross-domain scenarios

the time slot scheduling mechanism can provide end-to-end deterministic service guarantee.
