Apparatus and method for bridging network messages over wireless networks
First Claim
1. An apparatus for bridging one device in a network to one or more other devices in the network using wireless transmission which comprises:
- a first bridging device adapted for installation in the network and configured to receive and send information, in a first language protocol from and to a first network device and to send and receive all or part of the information in a second language protocol, by wireless communication, to a second bridging device; and
said second bridging device adapted for installation in the network and configured to receive and send information, in the first language protocol from and to one or more second network devices and to send and receive all or part of the information in said second language protocol, by wireless communication, to the first bridging device.

Abstract
An apparatus and method for communicating DNP protocol messages across networks that maybe slower, less reliable, and/or bandwidth-cost-constrained are provided. A DNP Bridge server capable of sending/receiving messages to/from a DNP Master System, a DNP Bridge Slave Interface unit capable of sending/receiving DNP message to/from a DNP Slave Device are used. The DNP Bridge server and DNP Bridge Slave Interface act together to transparently link the DNP Master System to the DNP Slave Device over slow, unreliable networks. The DNP Bridge server and DNP Bridge Slave Interface use a combination of techniques to minimize message transmissions and DNP protocol errors over slow, unreliable networks.
