基于LDP的MPLS网络流量统计功能的研究

随着MPLS(Multi-Protocol Label Switch)技术的逐步成熟,其承载的业务越来越丰富,网络流量成为描述网络行为的重要指标之一.主要介绍了分布式设备中基于LDP(Label Distribute Protocol)的MPLS网络流量统计功能的实现,详细阐述了系统模块的交互关系、处理流程以及主要的函数接口与数据结构,最后对该功能进行组网测试.测试结果证明了LSP(Label Switch Path)流量统计功能的有效性,能很好地满足用户、运营商的业务需求.

Research of traffic statistics function in MPLS network based on LDP

As the technology of MPLS develops, it carries more and more kinds of services. The network traffic is an important index to describe network behaviors. This paper mainly introduced realization of the traffic statistics of distributed device based on LDP(Label Distribute Protocol) in MPLS network; It analyzed module interactions, concrete processing flow, main functions and main data structures. Finally, this paper carried out the system test on MPLS network based on LDP, and the result shows that the scheme this paper puts up can achieve the statistics function of traffic effectively in LSP(Label Switch Path) and satisfy needs of users and service providers.
