The present invention relates to a method and apparatus for transmitting data over a WLAN mesh network. Transmission sections of priority frames and general frames are initially set, and the priority frame transmission section is varied step-by-step within a specific range. Thus, QoS with respect to data requiring the real-time property can be guaranteed and transmission of general frames can be guaranteed to some degree. Accordingly, there is an effect that data transmission efficiency can be improved significantly.

A packet forwarding apparatus forwards packets by hardware implementation in a packet switch system for an internet protocol service. In the packet forwarding apparatus, an interface transmits/receives a packet through interfacing with a data link layer. A bus operator converts the packet received from the interface by a pre-set logic. A header parser parses a header of the converted packet. A network search engine controller receives a parsed result and the packet from the header parser and controls a command for forwarding the packet by interworking with an external network search engine and a processor.
