Sichuan Telecom Mpls Vpn Network Of High-level Design

This text consults a great deal of famous work of MPLS( Multi-protocol Label Switch) technique first, elaborating the author to the MPLS technique principle and understandings of the direction, analyze the structure of MPLS data packet and the work principles, introduce some basic technical terms within technique of MPLS and the key technique, contrast the MPLS VPN(Virtual Private Network) and traditional VPNs on the realization of distinct, and introduced the QoS(Quality of Service) technique and characteristicses of the MPLS network.Then combine the circumstance of run-time of the network, detailed analysis the organization structure of Sichuan's network, the run - time circumstance and the problem of the equipment ,combine the need that the VPN business open demand, constitute the SiChuan telecommunication MPLS VPN network design project and norm standard.The author is from the dependability of the network and equipment, expansibility of the network, consistency of the design standard of the network, opening of network platform and the security of network platform, the advance of technology, management and maintenance of the network etc., define the basic principle of conceptual design, carry throughout the process that standardize the standard formulation.The design mainly includes three parts in the article: the network organization structure design, the layout of IP address and equipment assigns name to the norm, the MPLS VPN design .The network organization structure design part to define the design principle of the topological structure of the network mainly partly, have studied, analysed the basic situation of Sichuan telecommunication Internet and subject matter existing in operating of network, accord with VPN business open demand make telecommunication network of Sichuan organize the framework of goal, solve every key equipment ability insufficient , relaying circuit congested and VPN problem that business can't be launched. the layout of IP address and equipment assigns name to the norm part define the principle of IP address ,and has made the...
