Ethernet Enterprise Services - Internet, VPN Access, and Private Lines

Internet access is the most widely used GigE application. In addition, it is offered for point-to-point private lines within the metro area. Large hospitals, universities, and government offices use GigE. Examples include connectivity between health centers and locations where patient records and imaging files are stored. It is also used for connections to SANs that hold organizations' backup files.

Ethernet is also used to access VPNs. For example, customers might access national MPLS VPNs using Ethernet or GigE speeds, depending on the level of traffic at each of their sites. At remote or smaller sites without fiber connectivity, another service, perhaps T-1 or fractional T-1, might be used.
