摘要:

PTN具有端到端QoS、统计复用和集中网管的特征,在运营商网络上发挥了重要作用,SDN 具有智能控制、集中控制和开放的特征,目前发展很快。在两者特点剖析的基础上,分析了SDN引入PTN的必要性和基站业务、集客业务的应用场景,提出了SPTN的技术要求,并结合上海的试点与测试情况分析了SDN基本功能特点。最后,探讨了SDN引入后运营商网络在转发层和控制层的逐步演进路径。

Abstract:

With the features of end-to-end QoS, statistical multiplex and centralized network management, PTN plays an important role in a carrier network. SDN is developing quickly, having the characters of intel-controlling, centralized controlling and source-opened. Based on the characters, the necessity of the introduction SDN to PTN and application scenarios of base station and private line were discussed. Technical requirements of SPTN were proposed and the basic functions of SDN with the result of SPTN testbed in Shanghai CMCC were implied. Finally, the evolution road of transferred layer and controller layer in carrier network after the introduction of SDN was discussed.
