摘要
本文考虑5G布网对传输的超高带宽、低时延、网络分片等的需求以及千兆宽带对传输的高带宽、分光比和传输距离等性能优化的需求,对SPN和10GGPON技术发展部署进行分析,探讨了3层网络下移、网络分片、10GGPON的演进替换等关键问题,并通过建立模型对传输各层带宽进行测算,提出了SPN核心层、汇聚层、接入层的演进方向和组网特征,以及10GGPON的演进方式和比较。通过对基于SPN和10GGPON技术的“双千兆第一区”的建设和运营的研究,引发对后续传输网络的搭建和演进的思考。
The paper analyzes the development and deployment of SPN technology from theultra-high bandwidth requirement,low latency,network fragmentation etc.On 5G network,and the development and deployment of 10G GPON technology from high bandwidth,performance optimization requirements such as split ratio and transmission distance.Based on the above aspects,the paper explore the key issues such as layer three network downshift,network fragmentation,10G GPON evolution replacement.Evolution direction and networking characteristics of the SPN core layer,aggregation layer,and access layer and 10G GPON evolution and comparison been proposed,through calculate the bandwidth of each layer by establishing a model.Through the research o|n the construction and operation of the“double gigabit first zone”based on SPN and 10G GPON technology,the thinking about the construction and evolution of the subsequent transmission network is triggered.
