基于EOS的新一代IP承载网
首发时间:2007-01-22
摘要:本文描述了一种融合SDH(同步数字体系)、RPR(弹性分组环)和MPLS(多协议标签交换)为一体的新一代IP承载方案。以SDH为物理层,运用GFP(通用成帧规程)、VCat(虚级联)和LCAS(链路容量调整方案)等关键技术的EOS(Ethernet over SDH)平台实现了数据的高效传输。而进一步融合RPR和MPLS,可以在RPR提供共享带宽的基础上,通过MPLS提供端到端的QOS保证,QSR提供了融合EOS、RPR和MPLS的框架。

A new architecture of IP support networks based on EOS
Abstract:This paper described a new architecture of IP support networks which combined SDH, RPR and MPLS. EOS that takes SDH as the physics layer and makes use of the key techniques such as GFP, VCat and LCAS, has implemented the data transmission efficiently. While the combination of RPR and MPLS can support the peer to peer service QoS, basing the shares bandwidth provided by RPR. QSR provides this framework that combine EOS, RPR and MPLS.
