摘要:

分组传送网(PTN)凭借其技术优势已成为传送网络的主流技术之一。初期的PTN网络架构中L2/L3设备设置于核心层,从而存在网络安全性较差和系统承载能力较弱两大难题。结合中国移动网络现状,提出L2/L3设备设置于汇聚层的新型PTN网络架构,并将该架构与初期的PTN网络架构进行对比。结果表明,L2/L3设备设置于汇聚层的PTN网络架构在安全性和高效性上表现更优。

关键词: PTN网络架构, L2/L3设备设置, 网络安全性, 承载能力

Abstract:

Relying on technological superiority,packet transport network(PTN)technology has become the main force in the construction of the transport network.In the early PTN network architecture,the L2/L3 equipment was deployed in the core layer.Therefore,it will face two challenges of poor security and low network performance.Based on China Mobile’s current network,the new PTN architecture which L2/L3 equipment deployed in the convergence layer was proposed,and compared the network security and load capacity with L2/L3 equipment deployment in different level.The result shows that the new PTN architecture is better in terms of network security and efficiency.

Key words: PTN network architecture, L2/L3 equipment deployment, network security, load capacity
