摘要
总结了算力发展对光传送网的要求,光传送网应具备稳定大带宽、安全高可靠、确定低时延、智能化服务等特点。分析了面向算力网络的新型光传送网,及其在规划、维护和运营等方面应具备的能力和相关的技术要求。在规划方面,要关注400G高速系统、网络的可靠性、超低时延的网络架构等;在维护方面,需考虑多波段系统备品备件、功率动态控制,以及光电协同保护的配置;在运营方面,则应关注智能化的统计、分析、感知、预测等手段。
The requirements for optical transport networks in the era of computing power are summarized,which should have the characteristics of stable large bandwidth,high security and reliability,low and deterministic latency,and intelligent services.It analyzes the capabilities and related technical requirements of new-type optical transport networks oriented towards computing power networks in terms of planning,maintenance,and operation.In planning,attention should be paid to 400G high-speed systems,network reliability,and ultra-low latency network architectures.In maintenance,it is necessary to consider the spare parts for multi-band systems,dynamic power control,and the configuration of optical-electrical cooperative protection.In operation,focus should be on intelligent statistics,analysis,perception,and prediction methods.
