Abstract: A method for updating network connection parameters is disclosed, which comprises the steps of: providing a first device having a first NFC module while enabling the first NFC module to have network connection parameters stored therein; providing a handheld mobile device with a built-in NFC module; enabling the handheld mobile device to execute an application program (APP) so as to activate the built NFC module while enabling the NFC module to operate in an read/write mode; and moving the handheld mobile device near to the first device for allowing the network connection parameters stored in the first device to be transferred to the handheld mobile device via the first NFC module and thus stored into the built-in NFC module of the handheld mobile device.

Abstract: A network communication system is provided for communicating a wired subnet and a wireless subnet to solve the handover problems occurred in roaming. The system includes an IAPP manager program at a user level of the access point for communicating with a kernel-level device driver using system calls to perform an announce procedure and a handover procedure. A wireless LAN card driver with a packet filter is implemented for sending signals to the IAPP manager program to perform the handover procedure upon receiving a reassociation request packet from a mobile host. A wired LAN card driver is implemented for acting as an interface of the wired subnet. And a bridge program with a packet filter is implemented to increase the bandwidth efficiency.

Abstract: To improve the performance in terms of selectivity, responsiveness, and mean queueing delay for a connetion in ATM networks, a fuzzy leaky bucket method and apparatus is introduced that monitors and controls the sustainable cell rate of the connection utilizing a fuzzy increment controller (FIC) to dynamically adjust the value of the increment for the content of the leaky bucket incorporated for policing the connection. The adjustment of the increment by the fuzzy logic is accomplished through a set of linguistic rules based upon a domain knowledge. Two system parameters of the long-term mean cell rate and the short-term mean cell rate of the connection are fed into the fuzzy increment controller to adaptively calculate an appropriate increment value with an aim to achieve a better performance.
