Transmission of data over a low-bandwidth communication channel
First Claim
1. A system configured to transmit a stream of message over a communication channel in an electric power delivery system, the system comprising:
- a communications interface configured to receive a first message stream according to the first communications protocol, the message stream comprising a first plurality of individual data packets;
a packet parsing system configured to parse each message of the first message stream and to identify higher priority data and lower priority data contained within each data packet; and
a protocol translation system configured to generate a second message stream comprising a second plurality of packets according to a second format in which higher priority data is prioritized over the lower priority data;
wherein the second message stream is transmitted over the communication channel via the communications interface.

Abstract
Disclosed herein are various systems and methods that may improve the transmission of data over low-bandwidth communication channels in an electric power delivery system. Devices communicating across a low-bandwidth communication channel may implement several approaches, according to various embodiments disclosed herein, to reduce the data transmitted across the low-bandwidth communication channel and to prioritize the transmission of time-sensitive and/or more important information with respect to other data. Various embodiments disclosed herein may inspect packets to be transmitted across a low-bandwidth communication channel in order to identify high priority data. High priority data may be time-sensitive information, and accordingly, transmission of such data may be prioritized over other data in order to reduce transmission latency of the higher priority data.

15. A system configured to transmit a stream of message over a communication channel between stations in an electric power delivery system, comprising:
-
a first device configured to communicate according to a first protocol and a second protocol, the first device comprising; a first communications interface configured to receive a first message stream according to the first communications protocol, the message stream comprising a first plurality of individual data packets; a first packet parsing system configured to parse each message of the first message stream and to identify higher priority data and lower priority data contained within each data packet; a first protocol translation system configured to generate a second message stream comprising a second plurality of packets according to a second format in which higher priority data is prioritized over the lower priority data; wherein the second message stream is transmitted over the communication channel via the first communications interface; a second device configured to communicate according to the first protocol and the second protocol, the second device comprising; a second communications interface configured to receive the second message stream; and a second protocol translation system configured to generate a third message stream comprising a third plurality of packets by reformatting the second message stream according to the first protocol.
