Network Controller Mediator for Cross-Domain Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network control systems cannot remotely manage power supplies or collect information from devices across different security domains, limiting centralized control and management capabilities.
Innovation Solution
A network control system that includes a network controller and an information processor connected via specific communication paths, allowing for secure transfer and execution of special packets for power control and information management across different domains using the TCP/IP protocol, with the network controller generating and transmitting packets to external devices based on registered transmission sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If domains are completely separated for security, then security level is improved, but centralized control capability deteriorates
Solution Approach 1:
The network controller acts as an intermediary between the information processor and external devices in different security domains. It receives special packets from the information processor, generates appropriate packets based on packet conversion rules, and transmits them to external devices across domain boundaries, enabling centralized control while maintaining security isolation.
2Adaptability or versatility
If multiple communication paths with different standards are used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The network controller is designed with multi-functionality to handle multiple communication standards (TCP/IP and USB). It can receive packets from the information processor via TCP/IP communication path and transmit them to external devices via USB communication path, or vice versa, making it adaptable to different communication requirements without requiring separate dedicated controllers for each standard.

AI summary
A network control system includes a network controller, and an information processor connected to the network controller via a first communication path complying with a first standard. The network controller is connected to an external device via an another communication path complying with the first standard. In response to receiving a packet from a transmission source that is registered in advance, the network controller transfers the packet to the information processor via the first communication path. When the packet transferred from the network controller is a special packet that is registered in advance, the information processor notifies the network controller of a content of an instruction indicated by the special packet via a second communication path. The network controller generates a special packet including the content of the instruction notified from the information processor, and transmits the generated special packet to the external device via the another communication path.
