摘　　要：电力通信业务特别是新型算力业务对确定性承载的需求日益增长,而确定性网络(deterministic networking,DetNet)提供了有保障的传输服务,但如何路由和调度流量以保证端到端时延的有界仍是一个重要的研究方向。文章探讨了基于分段路由(segment routing,SR)技术的联合路由和调度方法,旨在解决在确定性网络中如何实现有界时延和较低丢包率的问题。通过仿真实验发现,该方法相比传统方法的循环指定排队和转发(cycle specified queuing and forwarding,CSQF),能够显著降低网络丢包率,并提供更低的延迟,为电力通信业务提供了可靠的传输服务。The demand for deterministic bearer in power communication services is growing increasingly,especially in new computing power services.Deterministic networking(DetNet)provides guaranteed transmission services.However,ensuring bounded end-to-end latency remains an important research direction.This paper explores a joint routing and scheduling method based on segment routing(SR)technology to address the challenge of achieving bounded latency and lower packet loss rates in deterministic networks.Through simulation experiments,it is found that this method,compared to traditional methods like CSQF,significantly reduces network packet loss rates and provides lower latency,thereby offering reliable transmission services for power communication businesses.
