Cloud Network Topology Testing via Dynamic Orchestration API
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network development and testing tools are limited by static configuration files that require the entire network topology to be taken down for modifications, and they only support process simulations that are not directly deployable on physical routers and switches, lacking flexibility and realism in virtual router and switch simulations.
Innovation Solution
A cloud-hosted sandbox environment with a unified API allows network developers to configure and test network topologies dynamically, using software images for virtual network elements that can emulate physical routers and switches, enabling flexible configuration and testing without requiring the network to be taken down, and ensuring that the test environment matches real-world topologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static configuration files are used to define network topology, then the system structure is simple, but any modification requires taking down the entire topology
Solution Approach 1:
The patent transforms the static configuration file system into a dynamic one by introducing an orchestration layer that can programmatically configure and reconfigure network elements. This layer enables runtime modifications to network topology without requiring complete system shutdown, allowing dynamic adaptation while maintaining operational continuity.
Solution Approach 2:
The orchestration layer acts as an intermediary between the control plane and data plane, mediating configuration changes. It receives high-level configuration instructions and translates them into specific actions for individual network elements, enabling modular and non-disruptive topology modifications.
2Ease of manufacture
If process simulations are used for virtual routers and switches, then the system complexity is reduced, but the simulations are not directly deployable on physical devices
Solution Approach 1:
The patent creates virtual copies of physical network devices that run simplified software images. These virtual instances replicate the essential behavior of physical routers and switches, allowing testing and development in a controlled environment while maintaining compatibility with actual deployment scenarios.
Solution Approach 2:
The system allows dynamic adjustment of software image parameters and device configuration settings. By modifying software parameters rather than rewriting entire simulation models, the system can adapt virtual devices to match physical device behavior, bridging the gap between simulation and deployment.
3Manufacturing precision
If the entire network topology is taken down for configuration updates, then configuration accuracy is ensured, but testing time and operational continuity are lost
Solution Approach 1:
The orchestration layer performs preliminary validation and verification of configuration changes before applying them to the network. Configuration instructions are checked for consistency and correctness in advance, ensuring accuracy while enabling incremental updates that maintain network operation throughout the process.
4Adaptability or versatility
If multiple interfaces are required for network development and testing, then functionality is comprehensive, but ease of operation is reduced
Solution Approach 1:
The patent merges multiple development and testing interfaces into a single unified orchestration layer. This consolidated interface provides comprehensive control over network element configuration, software image management, and topology modification, eliminating the need to switch between multiple tools while maintaining full functionality.
Solution Approach 2:
The orchestration layer is designed as a universal platform that performs multiple functions: configuring network elements, managing software images, validating configurations, and coordinating deployments. This multi-functional approach consolidates previously separate tools into a single system that handles the entire development and testing workflow.

AI summary
Presented herein are techniques to receive configuration instructions for elements of a network topology to be simulated and tested. In response to receiving and in accordance with the configuration instructions, a plurality of software images (for a plurality of virtual network elements of the network topology) are configured via an Application Programming Interface (API). The plurality of software images run in a cloud host. In response to receiving and in accordance with the configuration instructions, data is configured via the API, which represents one or more connections between the virtual network elements. A plurality of software images for the plurality of virtual network elements is then executed in accordance with the data representing the connections, for development and testing of the network topology.
