Nortel certification path for your help.2 VPN Overview Virtual Private Network (VPN) is deployed in public networks (Internet, frame relay, ATM, etc.) on a network for remote users, branch units, cooperative units and on the internal network to establish a secure tunnel to ensure secure transmission of data. VPN over the existing public network infrastructure to achieve, without expensive leased-line connection fees and long distance telephone charges, and use the same private network security, management and service quality strategies, the VPN within the unit can be seen as network expansion. Because of cost, easy to manage, easy to expand, safety, and other features to support a variety of emerging applications, VPN technology and product development and evolution of today's network of new components. Implementation of VPN tunneling technology is mainly theory, the use of the data package in the new tunnel encapsulates the original packet. Outside the tunnel endpoint address in the new header in the provided this header is called encapsulation header to assure that the data packets can be encapsulated through the tunnel, and the last destination address loaded in the original header. When a packet arrives when the end of the tunnel, the first stripped the package, the original header is used to route packets to their final destination. The current commonly used are Point to Point Tunneling Protocol Tunneling Protocol PPTP, Layer Two Tunneling Protocol L2TP, IPsec tunneling protocol network layer three [2]. VPN remote access VPN is currently in one of the main type of connection. Remote Access VPN for remote mobile users and home users of the park through the Internet (units) of the internal network for remote access. Another commonly used VPN connection type is VPN VPN devices and equipment, this approach is mainly used for co-operation units or affiliates and units through the Internet interconnection.3 Contivity Series Nortel Contivity is a highly integrated company VPN, stateful firewall, encryption, authentication, policy services, QoS and bandwidth management business VPN device. It is based on the standard tunneling technology, capable of IPsec, L2TP, PPTP, and L2F tunneling protocols to support the standard; in encryption support DES, 3DES and Advanced Encryption Standard (AES), to provide maximum end to end transmission of data security; addition Certification is also available on a wide range of authentication options to support RADIUS, LDAP, and token cards and smart cards.
