The Design And Implementation Of The WLAN Monitoring System Driver And Research On Some Techlogy

Wireless LAN is the outcome of the computer network combined with wireless technology. Network processor is the key technology of the next generation network. This dissertation, which is divided into two sections, introduces my R&D work based on WLAN monitoring system and NP during the graduate studying period.The first section is the design and implementation of the WLAN monitoring system driver. First introduced topics background and the protocol WLAN & 802.11b, then introduced the structure and framework of the monitoring system driver. The others expounded on the procedures of driver designing based on the Windows system and Linux.The second section is the design & implementation of Firewall and NAT subsystem based on IXP2400.First, introduced the basic theory of network processors and the key technologies firewall, and then elaborated on the design and realization of the NAT subsystem based on IXP2400 firewall system.
