Solution Overview
Problem
Current methods for testing and implementing network topologies are complex, costly, and inefficient, often requiring multiple machines and networks to validate and deploy network configurations, which can be time-consuming and resource-intensive.
Innovation Solution
The method involves creating a virtual network within a single host using containers, virtual network stacks, and virtual switches to simulate arbitrary network topologies, allowing for testing and deployment of network configurations with reduced complexity and cost, increased efficiency, and higher utilization rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple machines and networks are used to test network topologies, then testing accuracy and reliability are improved, but device complexity and resource requirements increase
Solution Approach 1:
The patent creates virtual copies of network devices, interfaces, and topologies through software simulation. Virtual network interface cards (VNICs), virtual switches, and virtual network stack instances replicate the functionality of physical network components, enabling comprehensive network topology testing within a single host system without requiring multiple physical machines.
Solution Approach 2:
The patent transitions from physical network testing across multiple machines to a virtualized dimension where network topologies are simulated within software containers on a single host. This dimensional shift from physical to virtual space allows complex network configurations to be tested without proportional increases in physical hardware resources.
2Reliability
If multiple machines and networks are used to deploy network configurations, then deployment validity is improved, but time consumption and operational complexity increase
Solution Approach 1:
The patent enables preliminary testing and validation of network configurations in virtualized environments before actual deployment. Network stack instances and virtual topologies can be configured, tested, and validated in advance within containers, allowing issues to be resolved before production deployment without time-consuming reconfigurations.
Solution Approach 2:
Virtual copies of network configurations and topologies are created and tested in isolated container environments. These virtual replicas allow complete validation of network deployments including packet routing, switching, and protocol handling without affecting production systems or requiring repeated physical setup.
3Reliability
If physical network equipment is used for testing, then testing realism is improved, but cost and resource utilization efficiency worsen
Solution Approach 1:
The patent merges multiple network testing functions into a single host system through virtualization. Multiple virtual network stack instances, containers, and simulated network topologies are combined within one physical system, maintaining testing realism while dramatically improving resource utilization by eliminating the need for separate physical testing environments.
Solution Approach 2:
The virtualized network testing platform provides universal functionality to simulate various network topologies, protocols, and devices within a single system. The same host can test different network configurations, protocols, and scenarios by reconfiguring virtual components rather than requiring dedicated physical equipment for each test case.

AI summary
A method for testing a network topology. The method includes obtaining the network topology, where the network topology includes a number of nodes connected by at least one link. The method further includes instantiating a number of containers corresponding to the nodes, instantiating a number of virtual network stacks, and instantiating at least one virtual switch corresponding to the at least one link. The containers are subsequently connected to the virtual network stacks using the at least one virtual switch. At least one of the virtual network stacks is then configured to send and receive packets. Finally, the network topology is tested by sending a packet through at least one of the plurality of virtual network stacks and the at least one virtual switch, wherein a result of the testing is used to validate the network topology.
