Solution Overview
Problem
Current computer networks lack effective multiplexing control, allowing unwanted communications to occur, which wastes resources and poses security risks, as conventional switches cannot block unwanted connections and modify connection policies effectively.
Innovation Solution
An electronic communication control device that provides multiplexing control by analyzing and monitoring network traffic, blocking unwanted data while allowing desired traffic to pass, using hardware and software components to manage TCP/IP communications and translate between IPv4 and IPv6 protocols, embedded in network interface cards and routers to enhance security and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional switches are used for routing and switching data packets, then network connectivity is maintained, but multiplexing control is lacking and unwanted communications cannot be blocked
Solution Approach 1:
The patent introduces an electronic communication control device as an intermediary component between the network interface card and the conventional switch. This device intercepts and analyzes data packets, applying multiplexing control rules to block unwanted communications while allowing legitimate traffic to pass through. The control device acts as a mediator that adds security and control functionality without replacing the existing network infrastructure.
Solution Approach 2:
The control device performs preliminary analysis and filtering of data packets before they reach the conventional switch or network interface card. By examining packet headers, source addresses, and communication patterns in advance, the system can preemptively block unwanted communications, preventing waste of processing resources and reducing security risks before they materialize.
2Ease of operation
If all data packets are processed by network interface cards and computers, then complete communication control is achieved, but resources are wasted processing unwanted data
Solution Approach 1:
The patent extracts the multiplexing control function from the main data processing path of network interface cards and computers. The electronic communication control device is dedicated solely to analyzing packet headers and applying control rules, separating this function from the general-purpose data processing tasks. This extraction allows the main system to focus on legitimate communication while the control device handles filtering, reducing overall resource consumption.
Solution Approach 2:
The control system segments network traffic into desired and unwanted categories based on multiplexing control rules. By dividing the data stream and routing only legitimate packets to the network interface card while blocking unwanted traffic at the control device, the system avoids wasting processing energy on irrelevant data while maintaining comprehensive communication control.
3Adaptability or versatility
If multiplexing control is implemented at higher network levels, then control flexibility is maintained, but control effectiveness is reduced due to lack of low-level access
Solution Approach 1:
The patent implements multiplexing control at the data link layer (Layer 2) of the OSI model, which is a lower dimension than typical application-layer or transport-layer control mechanisms. By operating at this foundational level, the control device can inspect and filter packets based on MAC addresses, Ethernet headers, and link-layer protocols, achieving more precise control over network traffic while maintaining flexibility through configurable control rules.
