Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual static configuration is used to configure IP addresses, then IP address configuration is simple and direct, but it is very inconvenient when tenants need a large quantity of IP addresses and severely affects tenant's service experience
Solution Approach 1:
The system enables self-service IP address allocation through DHCP servers that automatically assign IP addresses to ECS instances without requiring manual static configuration. Tenants can dynamically obtain IP addresses through automated processes, eliminating the need for manual intervention and significantly improving both convenience and allocation speed.
Solution Approach 2:
The system pre-configures DHCP servers with IP address pools and allocation rules before tenants need them. When tenants create ECS instances or require additional IP addresses, the DHCP server is already prepared to automatically allocate addresses from the pre-configured pools, enabling rapid deployment without waiting for manual configuration setup.
2Manufacturing precision
If multiple IP addresses are configured manually for each ECS instance, then each IP address can be precisely controlled, but the configuration process becomes complex and time-consuming
Solution Approach 1:
The DHCP server acts as an intermediary between the IP address pool and ECS instances. It automatically manages the complex process of IP address allocation, assignment, and tracking, while tenants only need to simple operations like creating ECS instances. This intermediary handles the complexity internally while maintaining precision in IP address assignment through automated record-keeping and allocation logic.
Solution Approach 2:
The DHCP server provides universal IP address management capabilities that work across multiple ECS instances, VPCs, and scenarios. A single DHCP server configuration can serve numerous tenants and instances simultaneously, eliminating the need for separate manual configurations for each instance while maintaining precise control over IP address assignment through centralized management.
3Adaptability or versatility
If dynamic IP address allocation is implemented, then tenant service experience is improved and IP addresses can be obtained flexibly, but it requires additional DHCP server configuration and management
Solution Approach 1:
The system segments IP address management into separate DHCP server components that can be independently configured and managed for different VPCs, regions, or tenant groups. This segmentation allows flexible IP address allocation within each segment while keeping the overall system manageable through modular configuration. Each DHCP server instance handles specific allocation tasks, reducing the complexity burden on any single configuration point.

AI summary
This application provides a communication method and a communication device. A first dynamic host configuration protocol DHCP server configured to allocate a plurality of internet protocol IP addresses to an elastic network interface of a first elastic cloud server ECS may be configured based on first configuration information of a tenant, so that in a cloud service system, the elastic network interface of the first ECS can dynamically obtain the plurality of IP addresses by using the DHCP server, thereby facilitating use of the tenant and ensuring tenant's service experience.
