Abstract

As the technology of MPLS was widely used on backbone network,the Internet service providers provide the services of VPN based on MPLS for VPN users.There are a lot of security leaks in sevices of VPN based on MPLS while data packets are transported in it.Analyzes the structure of MPLS VPN and security defects existing in the VPN.Proposes a method by which IPSec is applied to MPLS VPN to enhance the security of user data.Studies the security functions and application ranges of IPSec.Put forward how to config the IPSec protocol in client edge devices of user's network.Realizes the protection of VPN user's data before the data enter into the backbone network and explains the working mechanism of IPSec packet.
