Redundancy Network Supervision Frame Multicast Information Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information sharing methods in networks require each device to support special protocols, leading to significant network overheads due to the periodic transmission of device information, which occupies a large quantity of network transmission resources.
Innovation Solution
An information sharing method in a redundancy network where a supervision frame is generated and sent in a multicast manner to detect the working state of other devices, incorporating device information without the need for a special sharing protocol, reducing network resource usage by carrying device information within existing supervision frames, such as those defined in the IEC 62439-3 standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a special sharing protocol (e.g., LLDP) is used for device information sharing, then information sharing between network devices can be implemented, but each network device must support the special protocol and a separate data frame must be transmitted, causing large network overheads
Solution Approach 1:
The patent combines device information sharing with the existing supervision frame transmission mechanism. Instead of using a separate data frame for information sharing, the device information is embedded into the supervision frame that is already being transmitted periodically for network supervision. This merging eliminates the need for separate information sharing transmissions, thereby reducing network overhead while maintaining effective device information sharing.
Solution Approach 2:
The supervision frame is given multi-functionality by incorporating both its original supervision function and the new device information sharing function. The supervision frame continues to detect working states of network devices while simultaneously carrying device information for sharing purposes. This universal approach allows a single transmission to serve multiple purposes, reducing overall network traffic.
2Loss of information
If a special sharing protocol is developed for information sharing, then device information can be shared, but development costs and device complexity increase
Solution Approach 1:
The existing supervision frame mechanism is made universal to handle both supervision and information sharing functions. Network devices only need to support the standard supervision frame format, and by extending this existing mechanism to carry device information, no additional protocol support is required. This avoids increasing device complexity while achieving information sharing.
Solution Approach 2:
The supervision frame, which is already being transmitted by all network devices for supervision purposes, is utilized to also provide the information sharing service. Each device's own supervision frame carries its device information, allowing devices to share information using their existing supervision transmission capability without requiring additional services or protocols.
3Loss of information
If device information is transmitted in separate data frames, then complete information sharing is achieved, but network transmission resources are occupied
Solution Approach 1:
The patent merges the device information transmission with the supervision frame transmission. The device information is embedded within the supervision frame structure, combining two transmission purposes into one. This eliminates the need for separate information data frames, thereby reducing the quantity of network transmission resources required while maintaining complete device information sharing.
Solution Approach 2:
The supervision frame serves multiple purposes: it performs network supervision by detecting working states and simultaneously carries complete device information for sharing. This multi-functional approach ensures that all necessary information is transmitted through a single channel, optimizing network resource utilization.

AI summary
An information sharing method includes that a first redundancy device generates a first supervision frame that includes device information of the first redundancy device, where the first supervision frame detects whether a second redundancy device on a transmission link on which the first redundancy device is located in the redundancy network is in a working state, where the first redundancy device is any redundancy device in the redundancy network; and where the first redundancy device sends the first supervision frame to the second redundancy device in a multicast manner. The device information of the redundancy device is carried in the supervision frame.
