MS-OTN网络不同业务类型的时延比较研究

Comparative Study on Delay of Different Service Types in MS-OTN Networks

近几年“时延(Delay/Latency)”已逐步成为一个重要的传输指标,“低时延”是高品质传输专线的典型需求之一。MS-OTN(Multi-Service Optical Transport Network)网络利用其丰富的开销字节,强大的网络能力和传输速率,能为2Mbps~100Gbps的不同业务类型所承载的高精品用户专线、云间互联、5G等新型业务提供服务。文章通过对MS-OTN网络不同业务封装类型的测试分析比较了各业务封装类型对于时延的影响,进而分析OTN时延影响关键因素,并结合网络部署情况,为各类需求提供出合理的业务选型方案。

In recent years,"Delay/latency"has gradually become an important transmission indicator,and"low latency"is one of the typical requirements for high-quality transmission dedicated lines.The MS-OTN(Multi Service Optical Transport Network)network utilizes its rich overhead bytes,powerful network capabilities,and transmission rates to provide services between 2M-100G rates and different types of services for high-quality user dedicated lines,cloud interconnection,5G,and other new types of services.By testing different business encapsulation types in the MS-OTN network,we analyze and compare the impact of each business encapsulation type on latency,and then analyze the key factors affecting OTN network latency.Based on network deployment,we provide reasonable business selection solutions for various needs.
