Packets filtering method in a wireless network system
First Claim
1. A method for filtering packets in a wireless network system, the wireless network system comprising a wireless access point wirelessly communicating with a plurality of first nodes, each of the first nodes delivering data to the access point by transmitting packets, each of the packets having a header for recording a source address code and a destination address code, the access point comprising a first list for storing a plurality of first addresses, a second list for storing a plurality of second addresses, a receiving module for receiving the packets transmitted from the first nodes, an identifying module, and a transmitting module for delivering data to a plurality of second nodes via a local area network, the method comprising:
- (a) utilizing one of the first nodes to transmit a first packet to the access point;
(b)utilizing the receiving module to receive the first packet transmitted from the first node;
(c) utilizing the identifying module to compare the source address code of the first packet with the first addresses of the first list and to compare the destination address code of the first packet with the second addresses of the second list; and
(d) utilizing the transmitting module to transmit the first packet to one of the second nodes if the source address code of the first packet corresponds to one of the first addresses of the first list and the destination address code of the first packet corresponds to one of the second addresses of the second list.

Abstract
Packets filtering method in a wireless network system. The method includes following steps: using a first node of the wireless network system to transmit a packet to a switch of the wireless network system, using a receiving module of the switch to receive the packet, using an identifying module of the switch to sequentially compare an address information of the packet with a plurality of address data of an address list, and using a transmitting module of the switch to transmit the packet to a second node via a local area network if the address information of the packet corresponds to one of the address data of the address list.
