  • Cisco enterprise customers have in the past relied heavily upon traditional WAN/MAN services for their connectivity requirements. Layer 2 circuits based on TDM, Frame Relay, ATM, and SONET have formed the mainstay of most low-speed WAN services. More recently, high-speed MAN solutions have been delivered directly over Layer 1 optical circuits, SONET, or through the implementation of point-to-point or point-to-multipoint Ethernet services delivered over one of these two technologies.

  • Abstract: The purpose of this white paper is to present discussion and findings that conclude that Cisco MPLS-based VPNs are as secure as their layer 2 counterparts such as Frame- Relay and ATM. This document details a series of tests were carried out on a Cisco router test bed validating that MPLS based VPNs (MPLS-VPN) provide the same security as Frame-Relay or ATM. ATM and Frame-Relay have a reputation in the industry as being secure foundations for enterprise connectivity. Essential items that make ATM and Frame-Relay a secure network were considered and tested on an MPLS-VPN.

  • A Virtual Private Network (VPN) is defined loosely as a network in which customer connectivity among multiple sites is deployed on a shared infrastructure with the same access or security policies as a private network. With the recent advent of marketing activities surrounding the term VPNs, from new technologies supporting VPNs to a flurry of VPN-enabled products and services, you might think that the VPN concept is a major technology throughput. However, as is often the case, VPN is a concept that is more than 10-years old and is well known in the service provider market space....
