The core technology of Devices World’s iSCADA is protected by a US patent No: 6,965,935 awarded on Nov 15, 2005 entitled “Network Architecture for Internet Appliances”.

This end-to- end Internet Protocol (IP) based architecture enables real time man-machine & machine-machine interaction whereby: -

• a plurality of users may access a particular appliance simultaneously;
• a particular user may access a plurality of appliances simultaneously; and
• a plurality of appliances may communicate with each other simultaneously.

Using our unique 3-tier “Device-Server-Client” architecture, any number of users may have simultaneous access to the data from any particular device without degradation of response times, which is not possible with conventional embedded servers on a point-to-point architecture.

The ability of a user to access any number of devices simultaneously makes this system an ideal Enterprise solution where fleet management of assets is usually an essential requirement.

This patented technology enables us to implement a system where appliances may be remotely monitored and controlled without the need for a public IP address, a permanent connection to the internet, or other heavy-duty internet gateways like a PC or an existing LAN. This is a very critical component of our technology where many existing internet-based monitoring and embedded internet systems fail to deliver. This technology makes it possible to deploy Devices World’s iSCADA solutions in a wide variety of circumstances, particularly in cost sensitive applications or when access to existing networking infrastructure is not available.
