Shandong Telecom IP VPN Network Management System Design And Implementation

With the continuous development of Internet technology, market users matures, how to better use of network resources, to provide users with economical and rational networking solutions to improve network efficiency, becoming the data network running an urgent need to address problems. VPN technology to build enterprise networks to provide a strong support, and as an efficient IP MPLS backbone network technology platform for the realization of IP VPN provides a flexible and scalable technology base. With MPLS technology development in recent years has gradually matured, on the one hand, VPN services can save user lanes occupancy costs, easy access, easy maintenance; hand MPLS technology provides a connection-oriented IP on their networks in the technology to provide a variety of services appropriate safeguards, so MPLS VPN has been widely recognized customers and become the main way for operators to develop IP VPN services.Through the study of basic VPN and MPLS technologies, as well as analysis of MPLS VPN network applications. Summed up the inherent security mechanisms MPLS VPN network, including BGP routing realization address isolation and isolation, hidden core network structure, as well as resistance to attacks. According to summarize network security needs, set up by today’s existing MPLS VPN network technology and experience in the actual configuration, made a series of improved security MPLS VPN implementations, including neighbor authentication, VRF routing control, network access lists use, etc. and on this basis, the completion of the MPLS VPN network security, specific design and implementation. On the one hand, can help to further strengthen MPLS VPN network security, making MPLS VPN and ATM or Frame Relay with a VPN equal or better security; on the other hand, it also helps to make up for lack of safety awareness MPLS VPN, and implement personnel MPLS VPN network security network to provide effective guidance.
