Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet control rules are set to prevent network loops during VPN configuration, then network reliability is improved, but device complexity and difficulty of operation increase due to requiring expertise to configure
Solution Approach 1:
The VPN termination device automatically detects and prevents network loops without requiring manual configuration of packet control rules. The device monitors its own network state and autonomously implements loop prevention, eliminating the need for expert intervention while maintaining network reliability.
Solution Approach 2:
A configuration server acts as an intermediary between network administrators and VPN termination devices. The server automatically generates and distributes appropriate packet control rules to prevent network loops, shielding users from the complexity of manual rule configuration while ensuring reliable loop prevention.
2Stability of the object's composition
If packet control rules are manually configured to prevent network loops, then network stability is improved, but loss of time increases due to requiring expertise and time for setup
Solution Approach 1:
The system performs preliminary configuration of packet control rules automatically during VPN setup. The configuration server pre-generates appropriate loop prevention rules and distributes them to VPN termination devices before network operations begin, eliminating the time-consuming manual configuration process while ensuring network stability.
Solution Approach 2:
VPN termination devices automatically configure their own packet control rules based on real-time network conditions. The devices monitor for potential loops and autonomously adjust their routing behavior, eliminating the need for manual configuration while maintaining network stability.
3Reliability
If complex packet control rules are implemented to prevent network loops, then network reliability is improved, but ease of operation deteriorates due to complicating network control
Solution Approach 1:
The VPN termination device implements automatic loop detection and prevention mechanisms that operate transparently without requiring user intervention. The device autonomously monitors network traffic patterns and adjusts packet control rules as needed, maintaining reliability while preserving operational simplicity.
Solution Approach 2:
The configuration server serves as an intelligent intermediary that automatically generates, distributes, and manages packet control rules. This shields network operators from complexity while ensuring reliable loop prevention through professionally configured rules that are automatically applied across the VPN network.

AI summary
A communication system includes multiple VPN termination devices that perform a first VPN communication and a configuration server that configures the first VPN communication. Each of the VPN termination devices includes a first processor programmed to implement a configuration information receiver that receives configuration information for the first VPN communication sent from the configuration server, a communication controller that controls the first VPN communication based on the configuration information, and a first VPN communication unit that performs the first VPN communication with another one of the VPN termination devices according to a control of the communication controller.
