Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network device management requires manual configuration of IP addresses, leading to burdensome and error-prone processes, often resulting in broadcast storms and inefficient bandwidth utilization during network expansion.
Innovation Solution
A method and device for forwarding network packets that automatically determine a forwarding path using prestored identifiers and mapping relationships, allowing network management devices to generate and deliver configuration information to new devices without manual intervention, thereby establishing communication channels efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of IP addresses is performed at each site during network expansion, then network devices can be individually configured and managed, but the configuration process becomes complicated and tedious, putting a great burden on engineering personnel
Solution Approach 1:
The system enables self-service configuration where the network management device automatically discovers new online network devices through ARP requests and configures them without manual intervention. The new device automatically sends ARP requests, the management device responds with configuration information, and the device integrates itself into the network autonomously, eliminating the need for engineering personnel to manually configure each device.
Solution Approach 2:
The network management device performs preliminary actions by pre-configuring template information and automatically generating configuration data before new devices need to be deployed. When a new device comes online, the configuration is already prepared and can be automatically applied, avoiding the need for manual configuration at the time of deployment.
2Extent of automation
If broadcast is used throughout the whole network to discover new devices, then device discovery can be achieved without manual configuration, but broadcast storms occur and network bandwidth is occupied, wasting network resources
Solution Approach 1:
Instead of broadcasting configuration requests throughout the entire network, the system implements local quality by restricting ARP requests and configuration exchanges to only the local segment where a new device has come online. The new device sends ARP requests only on its local interface, and the management device responds through the appropriate forwarding path, ensuring that configuration traffic remains localized and does not propagate unnecessarily through the entire network.
Solution Approach 2:
The system introduces an intermediary mechanism where the network management device acts as a mediator between new online devices and the network. Rather than allowing direct broadcast throughout the network, the management device receives ARP requests, processes them through the forwarding path determination, and provides configuration information through controlled channels, thus mediating the discovery process to prevent broadcast storms.
3Reliability
If manual configuration steps are performed for each new network device, then proper identification and data interaction can be established, but the process is time-consuming and reduces productivity during network expansion
Solution Approach 1:
The system enables self-service configuration where the network management device automatically discovers new online network devices through ARP requests and configures them without manual intervention. The new device automatically sends ARP requests, the management device responds with configuration information, and the device integrates itself into the network autonomously, eliminating the need for engineering personnel to manually configure each device.
Solution Approach 2:
The system implements feedback mechanisms where the network management device monitors ARP requests from new devices, automatically processes configuration needs, and provides real-time configuration information. This closed-loop feedback system ensures proper device identification and configuration while dramatically reducing the time required compared to manual processes.

AI summary
Disclosed are a method and device for forwarding a network packet. A network device to be configured initiates automatically a network packet forwarding request including a forwarding identifier. When there is a prestored forwarding identifier consistent with the forwarding identifier in the network packet forwarding request, a forwarding end determines a forwarding path corresponding to the network packet forwarding request, and forwards to a network management device information of the network device to be configured in the network packet forwarding request according to the determined forwarding path, so that the network management device generates network configuration information of the network device to be configured according to the received information, and delivers the generated network configuration information to the network device to be configured.
