Multiple media fail-over to alternate media
First Claim
1. A method for providing automatic fail-over service for premises equipment that is accessing a network via a first network access medium, the fail-over service providing fail-over from the first network access medium to a second network access medium, the method comprising:
- at the premises equipment, responding to a first network ping received from a location remote from the premises equipment through the network and through the first network access medium;
at the premises equipment, responding to a second network ping received from the location remote from the premises equipment through the network and through the second network access medium;
at the premises equipment, receiving a message from the location remote from the premises equipment to change from accessing the network via the first network access medium to accessing the network via the second network access medium; and
at the premises equipment, in response to the message, changing from accessing the network via the first network access medium to accessing the network via the second network access medium.

Abstract
The present invention is a system and method for failing over from a current network access medium to an alternative network access medium. A customer premises equipment (CPE) box has ports for connections to a network through several network access media, such as high speed cable connections, DSL connections and dial-up connections. QoS parameters for each of the connections are monitored from a bandwidth manager remote from the CPE box. When it is determined that a fail-over would be beneficial, a message is sent from the bandwidth manager to the CPE box containing a command to fail-over and an identity of the alternate network access media.

9. A customer premises equipment box with automatic fail-over service between first and second network access media connections to a wide area network, comprising:
-
a first connection port connecting to the network via a first network access medium; a second connection port connecting to the network via a second network access medium; a processor and a tangible computer readable memory containing computer-executable instructions that, when executed by the processor, perform the operations of; transmitting a first ping response through the network and through the first network access medium, to a location remote from the customer premises equipment box; transmitting a second ping response through the network and through the second network access medium, to the remote location; receiving a command from the remote location to fail-over from the first network access medium to the second network access medium; and in response to the command, failing over from the first network access medium to the second network access medium. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
