通过对基于MPLS-TP协议架构下的新一代光接入传送技术的深入解析及应用探讨,展示了基于业务需求的各种技术的具体应用。应用探讨中着重对QOS的实现机制分析,根据流量及区分提出了一种端对端的QOS业务保障模型,并给出了具体的实施方案。另外,结合实际对OAM、时间同步及L3业务的需求进行了解析,提出了具体的应用及实施方案,并给出了具体的性能测试数据,对于PTN的实际具体应用具有较强的指导意义。
Through in-depth analysis and application of a new generation of optical access transmission technology based on the MPLS-TP protocol architecture, the application of various technologies based on service requirements is demonstrated. In the application discussion, we focus on the analysis of the implementation mechanism of QOS, put forward an end-to-end QOS service assurance model based on the traffic and the distinction, and give a specific implementation plan. In addition, the actual application of OAM, time synchronization and L3 service are analyzed. The concrete application and implementation plan are given, and the specific performance test data is given, which is of great guiding significance for the practical application of PTN.
