Application Research of MPLS VPN All-in-One Campus Card Network Based on IPSec

Abstract

This paper describes the MPLS VPN technology and IPSec protocol, and explains how the technology which is based on the IPSec MPLS VPN technology works and how to put this kind of technology into practice. Through the profound research of the advantages and disadvantages of the MPLS VPN and the IPSec technology, I have worked out a solution named the MPLS VPN ALL-in-One Card Network based on IPSec and its practicable model. This solution has not only the high-speed exchange of MPLS VPN, excellent quality of QoS and good expandability, but also the assurance of the high security and dependability of IPSec. This paper gives the detailed description of the comprehensive and effective applications of the MPLS VPN network technology used in the all-in-one campus card network in universities with multi-campuses in the multi-service system like the teaching, management, finance and the campus life, etc, by showing the campus network construction example between one university's main campus and its other campuses.
