OPEN REAL-TIME ETHERNET PROTOCOL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240322926 titled 'OPEN REAL-TIME ETHERNET PROTOCOL

The abstract describes a real-time Ethernet (RTE) protocol that includes start-up frames for network initialization, device discovery, parameter distribution, and time synchronization, followed by data exchange frames for communication between master and slave devices.

  • Start-up frames originated by a master device include device discovery frames, parameterization frames, and time synchronization frames.
  • Data exchange frames exclude source and destination addresses and include a header, type field, status field, and data payload.
  • The status field in start-up frames indicates the current protocol state for slave devices to dynamically switch frame forwarding modes.

Potential Applications: - Industrial automation - Process control systems - Communication networks

Problems Solved: - Efficient network initialization - Seamless communication between master and slave devices - Precise time synchronization

Benefits: - Improved network performance - Enhanced data exchange efficiency - Simplified network management

Commercial Applications: Title: Real-Time Ethernet Protocol for Industrial Automation This technology can be used in various industries for real-time communication and data exchange, improving overall system efficiency and productivity.

Prior Art: Further research can be conducted in the field of real-time Ethernet protocols and their applications in industrial automation and communication systems.

Frequently Updated Research: Stay updated on the latest advancements in real-time Ethernet protocols and their impact on industrial automation and communication networks.

Questions about Real-Time Ethernet Protocol: 1. How does the protocol ensure precise time synchronization between master and slave devices? 2. What are the key differences between start-up frames and data exchange frames in the protocol?


Original Abstract Submitted

a real-time ethernet (rte) protocol includes start-up frames originated by a master device for network initialization including a preamble, destination address (da), source address (sa), a type field, and a status field including state information that indicates a current protocol state that the ethernet network is in for the slave devices to translate for dynamically switching to one of a plurality of provided frame forwarding modes. the start-up frames include device discovery frames at power up, parameterization frames that distribute network parameters, and time synchronization frames including the master's time and unique assigned communication time slots for each slave device. after the initialization at least one data exchange frame is transmitted exclusive of sa and da including a preamble that comprises a header that differentiates between master and slave, a type field, a status field excluding the current protocol state, and a data payload.
