Packet Forwarding Match Logic to Reduce Network Flooding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network bandwidth resources are wasted due to the flooding of packets in network devices, as not all devices in a network need to receive the packets.
Innovation Solution
A packet processing method where network devices determine specific target devices based on match object and condition information, performing forwarding or discarding processing accordingly, thereby preventing unnecessary packet distribution across the entire network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network device forwards packets in a flooding manner to all neighboring devices, then all devices can potentially receive the packet, but network bandwidth resources are wasted because not all devices need to receive the packet
Solution Approach 1:
The patent segments the network device set into target network devices (matching the match condition) and non-target network devices (not matching). Instead of flooding packets to all devices, the system divides the network into relevant and irrelevant segments, sending packets only to the relevant segment (target devices), thereby reducing unnecessary bandwidth consumption while ensuring complete delivery to needed devices
Solution Approach 2:
The patent applies local quality by making different network devices have different packet reception rights based on their attributes. Target network devices (those whose attributes match the match condition) receive packets, while non-target devices do not. This localized differentiation ensures packets reach the right devices without wasting bandwidth on devices that don't need them
2Ease of operation
If a network device distributes intent information to all neighboring devices, then the distribution mechanism is simple and automatic, but excessive network bandwidth is occupied due to unnecessary packet flooding
Solution Approach 1:
The patent segments the distribution process into matching operations. The first network device evaluates match conditions against neighboring device attributes to identify target devices, then distributes intent information only to those targets. This segmentation maintains automation while eliminating the need to flood all devices, reducing bandwidth occupation
Solution Approach 2:
The patent implements self-service by enabling the first network device to autonomously evaluate match conditions and automatically determine which neighboring devices should receive intent information. The system uses pre-stored attribute information to self-identify target devices without manual intervention, maintaining ease of operation while reducing unnecessary traffic

AI summary
The present invention provides a packet processing method and system, and a network device. The method includes: receiving, by a first network device, a packet, where the packet includes match object information and match condition information; determining, by the first network device, a to-be-matched second network device according to the match object information, where the second network device includes one or more network devices; matching, by the first network device, device information of the second network device with the match condition information; and performing, by the first network device, forwarding processing or discarding processing on the packet according to a match result of matching the device information of the second network device with the match condition information. By using the method provided in the present invention, excessive occupation of network bandwidth can be reduced, and network resources can be saved.
