摘要
分组传送网是网络融合的产物,在电信行业全业务运营背景下,这一技术代表了传送承载网络的IP化发展趋势。文章就分组传送网的关键技术特征、实现技术原理进行了概括的分析,详细介绍了基于T-MPLS/MPLS-TP的分组传送网设备组网性能的测试方法和面临的问题。
Packet transport network （PTN） is a convergence network of SDH and IP. Under the background of full services operation, this technology represents the development trend of transmission network. This paper discusses the key technology features, implementation principles of PTN, and introduces the network performance testing method which is based on T-MPLS/MPLS-TP.
