【摘要】 讨论了在多个 IDC(数据中心 )所组成的骨干网络上实施流量工程的关键问题 ,首先分析了传统 SPF算法的缺陷 ,给出了流量工程的基本概念 ,阐述了 MPLS,REVP,IS-IS协议以及相互关系 ,然后给出了在 MPLS网络实施流量工程的几个问题和解决方法 ,最后给出了在IP骨干网络上实施流量工程的成功案例。更多还原

【Abstract】 This paper discusses traffic engineering with multi protocol label switching (MPLS) in a backbone of Internet data center (IDC) network. The traditional SPF routing limitations are analyzed and the traffic engineering concept is given. MPLS, resource reservation protocol (RSVP) and enhanced link status Protocols intermediate system to intermediate system (IS IS) are reviewed to provide a background for traffic engineering, the general issues of designing an MPLS system of IDC network for traffic engineering are then discussed. Finally a practical example with MPLS traffic engineering is shown.更多还原
