VRRP Master Device Version Inquiry Reduces Redundant Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VRRP protocols generate a large quantity of redundancy messages when a Master device sends messages to Backup devices of different versions (V2 and V3), leading to increased data transmission and bandwidth occupation between Master and Backup devices.
Innovation Solution
A method where a Master device sends a version inquiring message to Backup devices in a VRRP group, receives version information, and selectively sends either a V2 or V3 message based on the version of the Backup devices, ensuring only one-version messages are transmitted, thereby reducing redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the Master device sends messages in both VRRP V2 and V3 to Backup devices, then compatibility between V2 and V3 devices is maintained, but a large quantity of redundancy messages are generated, increasing data transmission and occupying bandwidth
Solution Approach 1:
The Master device performs a preliminary version inquiry by sending a version inquiring message to Backup devices before sending actual VRRP messages. Based on the version information obtained from the version responding message, the Master device selectively sends either V2 or V3 messages, avoiding the generation of redundant messages and reducing bandwidth occupation while maintaining compatibility with mixed-version devices
Solution Approach 2:
The patent applies different message versions (V2 or V3) to different Backup devices based on their specific version capabilities. The Master device individually queries and identifies the version of each Backup device, then sends appropriately matched messages, ensuring local optimization of message transmission for each device rather than using a uniform approach

AI summary
The present invention is applicable to the field of communication, and provides a virtual router redundancy protocol based message sending and receiving method, apparatus and system. The message sending method comprises: sending a version inquiring message to a backup device in a VRRP group by a master device in the same group; receiving a version responding message sent by the backup device, and acquiring the version information of the backup device according to the version responding message; and selecting one of a VRRP V2 message and a VRRP V3 message according to the version information of the backup device and sending the selected message to the backup device in the VRRP group. The technical solution provided by the present invention has advantages of decreasing redundancy messages, and decreasing the amount of data transmitted between the master device and the backup device.
