Wireless/LAN router queuing method and system
View Patent ↗A queuing method and system for wireless/LAN routers processes and routes an incoming data packet from a wireless mobile network to a destination server. The system uses a wireless transport module to initiate storage of the data packet in a permanent storage device while simultaneously forwarding the data packet to the destination server. A database thread is used to manage the operations being performed on the data packet and for initiating the storage of the data packet in a permanent storage device based on a permanent storage queue. A main thread is used to simultaneously forward the data packet to the destination server. The wireless transport module is adapted to determine whether the data packet has been acknowledged by the destination server and aborting the storage of the data packet in the permanent storage device once acknowledgment from by destination server has been received.
