摘要
Abstract
At present,the IP of electric power communication has become a general trend.Although the tradtional time division multiplexing(TDM) business is small in quantity,its requirement for reliability and real-time are extremely high,which is very important for the security and stability of power grid.As a result,the coexistence of multi-service situation is inevitable in the future.The integration of the existing synchronous digital hierarchy (SDH) or packet transport network (PTN) with OTN network,which can satisfiy the network requirements for service quality and transmission reliability,is an important technical problem that needs to be studied.Based on an analysis of the new demand of electric power business and network models,the application prospect of packet-enhanced optical transport network (P-OTN) technology is explored,and the network model and business bearing strategy are proposed,which can unify business bearing and ensure the quality of TDM service.关键词
