System and method for processing link failure of broadband access devices

Abstract

The present invention relates to a system and a method for handling link failure of broadband access devices in the field of communication technology. Said system for handling link failure of broadband access devices installs a status monitoring module and a failure handling module, which are used to monitor the working status of the uplink for a broadband access device and provide clients accessing said device with an emergency communication channel by enabling IP layer functions or the Internet layer-2 interoperability functions of the Ethernet when said link is interrupted. The present invention solves the problem of legacy broadband access devices being unable to provide emergency communication channels for clients accessing said broadband access device in case the connection between said broadband access device and its upper layer network fails.
