Method and apparatus for providing universal web access functionality
First Claim
1. An apparatus for providing universal web access functionality comprising:
- a first electronic device having a plurality of configurable Input/Output ports;
a network connection to said first electronic device on a first one of said plurality of configurable Input/Output ports;
at least one second electronic device connected to said first electronic device on a second one of said plurality of configurable Input/Output ports, wherein said first electronic device serves web pages associated with said at least one second electronic device, wherein configuration parameters for said second one of said plurality of configurable Input/Output ports are set using a browser interface to said first electronic device;
a tri-state buffer, said tri-state buffer being removed out of tri-state mode and driving a pull-up resistor high to generate output high on at least one of said plurality of configurable Input/Output ports; and
an open collector output driver, said open collector output driver being set to low impedance mode to generate an output low at said second one of said plurality of configurable Input/Output ports.

Abstract
A flexible electronic asset management system using Ethernet connectivity for electronic devices is presented. The invention enables multiple electronic devices to be controlled, monitored, and accessed from any browser connected to a computer network. A flattened stack approach is used to process network packet data. The flattened stack approach treats the network packet as a single string of data and uses the first few bytes of information to decide whether to drop or process the incoming data thus providing for faster network traffic processing. Since the lowest layer of the OSI stack has knowledge of what applications are active in the upper layers, the flattened stack allows the packet to be discarded at the earliest possible point so no processing power is wasted. The flattened stack also organizes its check/processing based on the raw data stream thus minimizing buffer requirements and providing for easier implementation into hardware.
