THE METHOD OF IMPLEMENTING VLAN ON THE DEVICE OF WIRELESS LAN ACCESS POINT

摘要

The method of implementing VLAN(virtual local area network) on the device of wireless LAN access point, divide the access device of distributed system to management domain; allocate the unique management domain identifier for each radio terminal; divide the accessed radio terminals to subscriber domain , allocate the unique subscriber domain identifier for each radio terminal; the access point device package the data frame as the data frame having VLAN label, transferring to distributed system; the access point device check the received data frame whether it has VLAN label; discard the data frame which have not VLAN label; with the data frame having VLAN label, check the matching related to VLAN identifier; if no matching then discarding the data frame; if matching , after taking off VLAN identifier of the data frame then forwarding it. adopting the method of the invention, capable of implementing the free switching of radio terminals when establishing networks about the different domain, decrease the dependability for the external exchange when establishing networks, saving the cost of establishing networks, improving the security of network.
