Abstract
A method for an access network device to access a network is disclosed, which comprises: powering on an access switch, and setting in its internal downlink protocol packet address table that all downlink protocol packets are to be oriented to a CPU module; receiving, by the access switch, a downlink protocol packet sent from a node server and orienting the downlink protocol packet to the CPU module of the access switch, and generating, by the CPU module, an uplink protocol packet and sending the uplink protocol packet to the node server, wherein the downlink protocol packet contains an access network address that is to be allocated; sending, by the node server, a network access command to the access switch, wherein the network access command contains an access network address of the access switch, and the access network address is the access network address to be allocated; and updating, by the access switch, its internal downlink protocol packet address table, as orienting only a protocol packet with a destination address being its own access network address to the CPU module. The present invention can guarantee a stable transmission rate of the data packet transmission and avoid …
