Abstract:
Disclosed are a data transmission method and a network device. The data transmission method is applied to virtual customer premise equipment (vCPE), and the vCPE supports a layer 2 data forwarding function. The method comprises: receiving a first packet from a first family terminal, wherein the first packet comprises a first family identifier; if the first packet is a first packet of a first family matching the first home identifier, sending a family authentication request to a remote authentication dial in user server (RADIUS); receiving family authentication success information returned by the RADIUS; and if a second packet from the first family terminal is received, sending the second packet to a value-added service platform (VSP) server. By implementing the embodiments of the present invention, the network security can be improved.
