Overview of VPN Technologies :: essays research papers

Multi- trafficker interoperability for virtual private networking is essential in forthwiths networking environment due to the nature of business acquisitions, the need to deport corporate networks to contractors and partners, and the diverse equipment within company networks. To ensure customers have an sensory(a) solution, Microsoft Windows Server 2003-based VPN technology is based on industry standards. By backing IETF industry standards, Microsoft delivers a VPN solution that will work with other standard-compliant devices or software systems, helping to lower the cost and complexity of supporting proprietary solutions. Customers who use standards-based technology are not locked into any given vendors proprietary implementations. Microsoft supports the IETF efforts to standardize VPN technology. To date, two major technologies are IETF standards      mold Two Tunneling Protocol (L2TP)a combination of PPTP and Ciscos socio-economic class 2 Forwarding, wh ich evolved through the IETF standards process.      internet Protocol Security (IPSec)an architecture, protocol, and related Internet Key Exchange (IKE) protocol, which are exposit by IETF RFCs 2401-2409.The combination of these technologies is described in RFC 3193, an IETF Proposed Standard.In addition to IETF standards-track technologies, Microsoft supports PPTP, created by the PPTP Industry Forum (US Robotics now 3Com, 3Com/ immemorial Access, Ascend, Microsoft, and ECI Telematics.) PPTP is a published informational RFC (RFC 2637) and has many companies shipping third-party implementations.For advanced security requirements, IPSec has emerged as a key technology. However, IPSec tunnel mode by itself does support bequest authentication methods, tunnel IP address assignment and configuration, and multiple protocols all critical requirements for remote access VPN connections. To provide a truly practical solution, Windows Server 2003 uses L2TP in combination with IPSec to provide an interoperable, secure VPN solution. L2TP has broad vendor support, particularly among the largest network access equipment providers, and has verified interoperability in a serial of vendor-sponsored testing events.
