Remote-Access Technologies

Based on the needs of the users just described, a wide range of technologies can be used to provide remote access. Some of the traditional technologies include Frame Relay, leased lines, ISDN, and dialup links. Newer technologies include DSL, cable modems, and wireless technologies such as 802.11x.

VPNs have also become a significant technology in the past few years. They can provide an alternative to expensive leased lines in a central office/branch office scenario. Also, they can provide security to users who use them over DSL and cable modem networks to connect to the central office. IPSec VPNs are a good example of the latter scenario.
