  • Patent number: 6674767
    Abstract: A flexible gateway accommodates data transfer from a data origination device over a wide variety of networks to a wide variety of destination devices, even if those networks use different protocols, and even if the devices recognize different data formats. Thus, the gateway can perform work previously requiring numerous gateways. After the gateway receives information from a data source, the gateway identifies the specific device type and the specific network type to which the information is to be routed. The gateway then calls device and network drivers associated with the specific device and network identified with the destination device. These drivers then manipulate the data using the device driver into the format recognized by the destination device, and then provide the manipulated data to the destination device over the identified network using the compatible protocol. Thus, the destination device properly receives and interprets the information provided by the data source.
