Integrated Security Switch Merging Layer 2 and Layer 3 Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security solutions, such as unified threat management (UTM) devices, increase network complexity and administrative overhead due to the need for dedicated devices for switching and security, which can reduce the effectiveness of security devices in managing growing network traffic and blended threats.
Innovation Solution
An integrated security switch that combines Layer 2 and Layer 3 switching functionality with a unified management interface, enabling seamless connectivity and security management through a single interface driven by both command line and graphic user interfaces, reducing complexity and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated separate devices are deployed for switching and security, then network security functionality is provided, but network complexity and administrative overhead increase
Solution Approach 1:
The patent combines switching functions and security functions into a single integrated security switch device. The security module and switching module are merged into one system that can perform both packet forwarding and security processing (firewall, intrusion detection, virus filtering) simultaneously, eliminating the need for multiple separate devices and reducing network complexity.
Solution Approach 2:
The integrated security switch is designed as a multi-functional device that can perform switching operations and multiple security functions including firewall filtering, intrusion detection, virus scanning, and spam filtering. This universal device replaces multiple specialized devices, simplifying network architecture while maintaining comprehensive security capabilities.
2Reliability
If dedicated separate devices are deployed for switching and security, then security features are implemented, but administrative overhead increases
Solution Approach 1:
The patent merges the management interfaces of switching and security functions into a unified management system. Administrators can configure and monitor both switching parameters and security policies through a single interface, eliminating the need to separately manage multiple devices and reducing administrative overhead.
3Reliability
If dedicated separate devices are deployed for switching and security, then network security is provided, but effectiveness of security device is reduced due to traffic absorption by switch
Solution Approach 1:
By integrating the security module directly with the switching module, the system ensures that all traffic passing through the switch is automatically available for security processing. The security module can inspect and filter traffic without requiring separate physical connections or additional traffic copying, maximizing security effectiveness while maintaining switching performance.

AI summary
An integrated security switch and related method for managing connectivity and security among networks. The integrated security switch includes a security function connectable with a first network and at least one switching function connectable with a second network. A common management interface driven by both command line interface and graphic user interface protocols manages the switching function via a management path dedicated between the security function and the switching function. The common management interface enables secure switching of traffic to flow via a traffic path dedicated between the switching function and the security function. Typically, the traffic is a flow of data between the Internet and a group of networked users such as a wide area network.
