Patent ID: 8233385

Claim:
A method performed by a device, the method comprising: establishing, by the device, a first Point-to-Point Protocol (PPP) session on a first interface, the first interface including a component to receive data, from a network, during the first PPP session, and establishing the first PPP session including establishing a first link control protocol (LCP) session and a network control protocol (NCP) session on the first interface; receiving, by the device, an indication of a layer one failure on the first interface, the layer one failure relating to a malfunction of the component; and attempting, by the device and for a period of time, to establish, based on the indication of the layer one failure on the first interface, a second PPP session, the attempting to establish the second PPP session including: attempting to establish, during the period of time and based on the indication of the layer one failure on the first interface, a layer one switchover to a second interface, that differs from the first interface, and attempting, during the period of time and in response to establishing the layer one switchover to the second interface, to establish the second PPP session on the second interface, the attempting to establish the second PPP session on the second interface including: attempting, during the period of time, to establish a second LCP session on the second interface, the second LCP session being different from the first LCP session; and when the second LCP session has been established on the second interface, attempting, during the period of time and based on the second LCP session, to move the NCP session from the first interface to the second interface.
