Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex computer networks require accurate modeling to simulate changes without disrupting user access, as large networks are sensitive to modifications that could adversely affect them.
Innovation Solution
A system that creates a virtual representation of the network by gathering properties of physical and virtual network devices and links, using software to configure virtual network interface cards and containers, allowing for simulation of network changes before they are applied to the actual network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual model of the network is created to test changes, then network stability is improved, but device complexity increases
Solution Approach 1:
The patent creates a virtual copy of the physical network topology including virtual network devices, virtual network links, and virtual containers that replicate the behavior and relationships of physical components. This copying approach enables testing of network changes in isolation, improving reliability by preventing disruptions to the actual network while managing complexity through automated replication tools
Solution Approach 2:
The patent segments the network model into discrete virtual components (virtual network devices, virtual network links, virtual containers) that can be independently configured and tested. Each virtual component corresponds to a physical component, allowing granular control and simplified management of the overall network model complexity
2Reliability
If thorough network tests are performed before changes, then reliability is improved, but time consumption increases
Solution Approach 1:
The patent performs preliminary testing actions in the virtual network model before applying changes to the physical network. Virtual network changes are tested and validated in advance, allowing thorough reliability checks to be completed beforehand without extending the time required for actual network deployment
Solution Approach 2:
The virtual network model serves as an intermediary testing environment between the test engineer and the physical network. This intermediary layer enables comprehensive testing to be performed efficiently by isolating test activities from the actual network, preventing test-induced disruptions while maintaining testing thoroughness
