Network Connection Retrieval via MAC Address Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network architectures require manual reconfiguration of IP addresses for servers in a local area network, which is inefficient and time-consuming, especially when a server's IP address changes, as network administrators need to physically log in and re-establish connections manually.
Innovation Solution
A network connection retrieving method and system where a master device records unique identification information for each network device, allowing it to send broadcast packets to re-establish connections by identifying and reconnecting with devices using their pre-recorded unique identification information and new IP addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reconfiguration of IP addresses is used, then network connection can be established, but time consumption and operational complexity increase significantly
Solution Approach 1:
The system performs preliminary actions by recording the unique identification information (MAC address) of each network device in advance within the management server. When a device's IP address changes, the management server can immediately query the device using its pre-recorded MAC address and re-establish connections without manual intervention, thus resolving the contradiction between connection reliability and time consumption.
2Reliability
If manual reconfiguration is performed, then connection can be re-established, but operational complexity and human intervention requirements increase
Solution Approach 1:
The system implements self-service by enabling the management server to automatically detect IP address changes, query device information using pre-recorded MAC addresses, and re-establish network connections without requiring network administrators to manually log in to switches or physically visit each server. This automated approach maintains connection stability while dramatically simplifying operations.
3Productivity
If DHCP is used for IP assignment, then IP address management becomes automated, but loss of control over specific device IP addresses occurs
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring network devices for IP address changes and automatically responding to such changes. When a device's IP address changes, the management server receives feedback about the change, queries the device using its pre-recorded MAC address to obtain the new IP address, and updates its records accordingly. This allows DHCP automation while maintaining adaptability through automatic detection and adjustment.

AI summary
A network connection retrieving method and a network system are provided. The method is adapted for retrieving connections between network devices by a master device among network devices in a local area network, and includes: attempting to establish the connection with a current device according to a pre-recorded network address of the current device; sending a plurality of broadcast packets to each of the network devices in the local area network if the step of establishing the connection failed, and collecting a response message returned from each of the network devices in response to the broadcast packets; and identifying the response message returned from the current device by comparing unique identification information recorded in each of the response messages with pre-recorded unique identification information of each of the network devices, and using the network address recorded in the response message to re-establish the connection with the current device.
