Packet Transmission Method for IPL Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In link aggregation scenarios, broadcast packets are inadvertently transmitted across network devices, leading to invalid transmission and increased burden on Intra Portal Link (IPL) resources, which affects network stability and resource utilization.
Innovation Solution
A packet transmission method that determines whether an opposite DR-member device is connected to a specific type of device before sending packets, ensuring that broadcast or unknown unicast packets are only forwarded through IPL if the opposite DR-member device is connected, thereby preventing invalid transmissions and conserving IPL resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If broadcast packets are transmitted across network devices in link aggregation scenarios, then link redundancy and traffic load sharing are achieved, but invalid transmission occurs and IPL resources are burdened
Solution Approach 1:
The patent applies preliminary action by checking the connection status of the opposite DR-member device before transmitting broadcast or unknown unicast packets through the IPL. The transmitting device determines whether the opposite device is connected to a first type of device (connected to opposite DR-member but not local DR-member) in advance, and only forwards packets through IPL when the opposite device is connected, thereby avoiding invalid transmissions and conserving IPL resources
2Productivity
If broadcast packets are forwarded through IPL without connection verification, then traffic load sharing is implemented, but network stability is affected due to invalid transmissions
Solution Approach 1:
The patent implements feedback by having the transmitting device continuously monitor and determine the connection status of the opposite DR-member device before packet transmission. The device receives connection status information and uses this feedback to dynamically control whether to forward packets through IPL, ensuring that traffic load sharing is maintained while avoiding invalid transmissions that would compromise network stability
3Speed
If packets are transmitted without checking opposite device connection status, then transmission speed is maintained, but IPL resources are wasted on invalid transmissions
Solution Approach 1:
The patent applies preliminary action by performing connection status verification before packet transmission through IPL. The transmitting device determines in advance whether the opposite DR-member device is connected to a first type of device, and only forwards packets when connection is confirmed, thereby avoiding wasted IPL resources on invalid transmissions while maintaining efficient resource utilization

AI summary
The present disclosure provides a packet transmission method and apparatus. The method comprises: determining whether an opposite DR-member device is connected to a first type of device, where the first type of device is a device connected to the opposite DR-member device but not connected to the local DR-member device, wherein when required to send a packet of a specified type, the packet is sent to the opposite DR-member device if the opposite DR-member device is connected to the first type of device; and the packet is prohibited from being sent to the opposite DR-member device if the opposite DR-member device is not connected to the first type of device. With the technical solutions of the present disclosure, only when the opposite DR-member device is to forward the packet, the packet is sent to the opposite DR-member device through an IPL, thereby avoiding the invalid transmission of the packet, saving IPL resources, reducing the burden on the IPL, and improving the stability of the IPL.
