Network Tunnel Connection for Secure Enterprise Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communications between devices in enterprise campus networks can be cumbersome and prone to security compromises due to the dynamic nature of business operations and the presence of various interconnected devices.
Innovation Solution
Establishing a tunnel connection between a switch and a gateway in a network, and conducting data traffic, including DHCP and ARP messages, through this tunnel connection to ensure secure and efficient communication between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data traffic is conducted directly between devices in the network, then communication efficiency is improved, but network security deteriorates due to exposure to security compromises from various interconnected devices
Solution Approach 1:
The patent introduces a tunnel connection as an intermediary layer between the switch and gateway, encapsulating data traffic within protected channels. This tunnel acts as a mediator that allows direct communication efficiency while maintaining security boundaries, preventing unauthorized access and security compromises from propagating through the network.
2Ease of operation
If broadcast or multicast traffic is allowed to flow freely in the network, then device discovery and communication setup are improved, but network stability deteriorates due to traffic flooding and potential outages
Solution Approach 1:
The patent segments broadcast and multicast traffic handling by implementing tunnel-specific configurations that control traffic flow. The tunnel connection divides the network into controlled segments where broadcast/multicast traffic can be selectively permitted or blocked, preventing flooding while allowing necessary device discovery protocols to function within defined boundaries.
3Reliability
If a tunnel connection is established between switch and gateway, then network security is improved by filtering traffic, but device complexity increases due to additional connection management
Solution Approach 1:
The tunnel connection is designed to perform multiple functions simultaneously: it provides security filtering, enables controlled traffic flow management, supports both unicast and broadcast/multicast traffic types, and facilitates device discovery protocols. This multi-functionality reduces the need for separate security mechanisms and simplifies overall network management despite the added tunnel layer.
