- Abstract
- VPNs enable companies to connect geographically dispersed offices and remote workers via secure links to the private company network, using the public Internet as a backbone. Specially, VPN service in the broadband data communication network is very important and necessary to take in users who want to specify group communication. VPN mechanisms are needed which work over existing deployed backbones, and which can also be migrated to new backbones like MPLS. MPLS is the latest step in the evolution of multilayer switching in the Internet In this paper, we are trying to clarify how MPLS can be applied to creating VPNs. For that, we researched an architectural model for building VPNs in a MPLS domain. The proposed model takes advantage of both network layer peering and packet switching, and link layer circuit and per-stream switching. It comes with a design scheme and an implementation procedure for VPN service in MPLS system. And then we describe MPLS based VPN service procedures. And, we describe MPLS VPN schemes that must be accommodated with existing network backbones and also provide for a full range of QoS characteristics.
