Network Device Management Domain Determination via Packet Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual configuration of management domain information on each network device in a virtual cluster increases maintenance difficulty, making it challenging to manage and maintain large-scale virtual clusters effectively.
Innovation Solution
A method where a first network device sends a packet to a second network device containing a domain identifier and IP address set, allowing the second network device to determine its management domain without manual configuration, by checking if its IP address is included in the set, and storing the corresponding domain ID.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual configuration of management domain information is performed on each network device, then domain determination accuracy is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
Network devices automatically determine their management domain by receiving packets containing domain information and IP address sets from other devices. Each device autonomously checks whether its IP address is included in the received IP address set to determine domain membership, eliminating the need for manual configuration and reducing maintenance complexity while maintaining accurate domain determination.
Solution Approach 2:
Management domain information and IP address sets are pre-distributed to network devices through packets before actual domain determination is needed. This preliminary distribution of domain information allows devices to automatically and accurately determine their management domain without requiring manual configuration at the time of deployment or maintenance.
2Measurement precision
If manual configuration is used for each network device, then domain information accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
Network devices automatically obtain and process domain information by receiving packets from other devices in the virtual cluster. Each device independently determines its management domain by checking its IP address against the IP address set in the received packet, eliminating manual configuration operations and significantly improving ease of management while maintaining accurate domain information.
Solution Approach 2:
Packets serve as intermediaries to transmit management domain information and IP address sets between network devices. This intermediary mechanism automates the domain determination process, allowing devices to accurately obtain domain information without manual intervention, thereby improving both ease of operation and domain information accuracy.
3Reliability
If domain information is pre-configured on each device, then domain determination reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
Network devices automatically determine their management domain by receiving packets containing domain information and IP address sets during runtime. This self-service mechanism eliminates the need for manual pre-configuration during deployment, significantly easing the manufacturing and deployment process while maintaining reliable domain determination through automated IP address matching.
Solution Approach 2:
Domain information and IP address sets are prepared in advance and distributed to network devices through packets before actual domain determination is performed. This preliminary preparation and distribution enables automatic and reliable domain determination without requiring manual configuration during deployment, improving both ease of manufacture and domain determination reliability.

AI summary
A method for determining a management domain, the method comprising: receiving, by a second network device, a first packet sent by a first network device, where the first packet includes a domain ID of a first management domain and a first IP address set corresponding to the domain ID of the first management domain, and the first IP address set includes an IP address of a network device in the first management domain; and when the second network device determines that the first IP address set includes an IP address of the second network device, determining that the second network device belongs to the first management domain, and storing the domain ID of the first management domain.
