摘要
基于电力多业务承载需求与现有电力传输网网络架构,文章提出核心层、汇聚层以OTN+分组增强型OTN为主,接入层以SDH+PTN为主的网络架构演进方案;针对电力分组增强型OTN混合组网需求,提出可满足小颗粒和大颗粒业务共同承载的组网策略及相关建议;最后给出继电保护业务、系统保护业务承载的典型应用场景。
Considering the demand for power multi-service and current power telecommunication network architecture, this paper proposes a network architecture evolution plan in which the core layer uses OTN, aggregation layer uses packet enhanced OTN, and the access layer uses the SDH＋PTN in major. Regarding to the need of hybrid networking of packet enhanced OTN, this paper presents a networking strategy and suggestions which can carry large particles and small particles services： Finally, this paper presents the typical application scenes including relay protection service and system protection service.
