MPLS技术与LSR性能指标

MPLS TECHNOLOGY AND LSR PERFORMANCE METRICS

作为互联网的一种新技术,MPLS技术不仅扩展了LSR的功能,而且对LSR的性能起着决定性作用.本文针对MPLS技术,重点研究了LSR的性能指标,在对LSR的主要功能和数据流程加以分析的基础上,系统提出了几项主要的MPLS性能指标,阐明了在设备设计方面、网络管理方面、网络环境方面影响它们的诸多因素,总结了这些因素对它们的影响规律,指出了需要进一步研究的问题.

As a new network technology,MPLS not only enhances LSRs' functions,but also plays an important role in LSRs' performances.A study on LSR performance metrics is presented in the light of an analysis of LSRs' main functions and data flow diagrams.First,several LSR performance metrics are raised.Then some factors' impacts are illustrated,and future research work is indicated.
