摘要:
A method, an apparatus and a system for providing secondary or backup Internet access are disclosed. The system includes a local network server having a primary router for directing data to/from a primary Internet backbone and a secondary router for directing data to/from a secondary Internet backbone. The primary router is connected to a primary local communications circuit employing a primary transmission medium. A primary point of presence is connected to the primary local communication circuit, and thereby provides primary Internet access via a primary Internet backbone. The secondary router is connected to a secondary local communications circuit employing a secondary transmission medium different than the primary transmission medium. A secondary point of presence is connected to the secondary local communication circuit, and thereby provides secondary Internet access via a secondary Internet backbone. The system employs control logic for detecting a failure to provide Internet access via the primary router, and for directing communication to the secondary router. A method and an apparatus for providing secondary Internet access are also disclosed.
