Abstract:
1. A method for enabling data forwarding between different physical mediums, comprising: establishing, by a network access device, a first Point-to-Point Protocol virtual channel (PPP channel) based on a first physical medium and a second PPP channel based on a second physical medium; performing, by the network access device, channel negotiations with the first PPP channel and the second PPP channel respectively; and binding the first PPP channel with the second PPP channel indirectly without paying any attention to private features of the first PPP channel and the second PPP channel, and setting a relationship between the first PPP channel and the second PPP channel to be a binding relationship, when the channel negotiations of the two virtual channels succeed, to enable data forwarding between the first physical medium and the second physical medium; wherein, according to the binding relationship, PPP message is not parsed and transmitted transparently by adopting a binding forwarding mode of bridging principle; wherein the network access device enables the data forwarding between the first physical medium and the second physical medium through a core transceiving process, which comprises: converting, by a first physical medium core of the network access device, message data in a form of a first physical medium encapsulation transmitted from a first physical medium drive into message data in a form of a second physical medium encapsulation, and transmitting the converted message data to a second physical medium core through the bound first PPP channel and second PPP channel; transmitting, by the second physical medium core, the message data in the form of the second physical medium encapsulation to a second physical medium drive; or converting, by the second physical medium core of the network access device, message data in the form of the second physical medium encapsulation transmitted from the second physical medium drive into message data in the form of the first physical medium encapsulation, and transmitting the converted message data to the first physical medium core through the bound second PPP channel and first PPP channel; transmitting, by the first physical medium core, the message data in the form of the first physical medium encapsulation to the first physical medium drive.
