Abstract

Various methods and systems for handling and directing wireless packet data traffic is disclosed. In one embodiment, the system is a data switching system that includes a first data port interface coupled to a first data communication port, a second data port interface coupled to a second data communication port, and a data packet parsing engine responsive to the first data port interface and the second data port interface. The data packet parsing engine includes a wireless data packet evaluation routine to retrieve and evaluate content contained within the wireless data packet. In another embodiment, a method of processing wireless data traffic is provided. The method includes receiving the wireless data traffic at a gateway, evaluating a data packet within the wireless data traffic at the gateway to determine at least one of language information, user browser type information, and data content type information, and sending a data request to a particular computer server. The particular computer server is determined based on at least one of the language information, the user browser type information, and the data content type information.
