Solution Overview
Problem
Current methods for testing network application interoperability are cumbersome and require extensive expertise, especially with the rapid evolution of networking technologies, as they demand thorough understanding of multiple protocols and continuous updates, making it challenging to validate end-to-end message exchanges across diverse network technologies.
Innovation Solution
The use of natural language constructs and domain-specific language (DSL) to define and execute message signal transactions between network nodes, allowing for automated testing and performance data tracking, which simplifies the process by emulating system behavior without requiring complete state machine setup, thus enabling rapid development and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional testing methods are used to validate message exchange across multiple network technologies, then testing thoroughness can be improved, but the complexity of operation and expertise required increases significantly
Solution Approach 1:
The patent introduces an intermediary testing framework that mediates between the complex multi-protocol network environment and the tester. This framework automatically handles protocol-specific details, message format validation, and state machine emulation, allowing testers to validate message exchange across multiple network technologies without needing deep expertise in each protocol specification.
Solution Approach 2:
The patent creates simplified copies or models of the actual network protocols and state machines. Instead of requiring testers to work with the full complexity of real protocol specifications, the system uses emulated state machines and standardized message formats that replicate essential protocol behavior, making testing more accessible while maintaining thoroughness.
2Measurement precision
If complete state machine setup is used for testing network nodes, then testing accuracy is improved, but the time required for setup and execution increases
Solution Approach 1:
The patent performs preliminary actions by pre-defining state machine models, message formats, and test scenarios before actual testing begins. The system prepares emulated state machines and test configurations in advance, so that during execution, testing can proceed rapidly with minimal setup time while maintaining accuracy through the pre-validated test frameworks.
Solution Approach 2:
The patent segments the complete state machine into smaller, manageable state transition sequences that can be tested independently. Instead of setting up and executing one large comprehensive state machine, the system divides testing into modular state transition units, each validating specific protocol behaviors, reducing overall setup time while maintaining complete coverage.
3Manufacturing precision
If extensive protocol knowledge is required for testing, then testing depth can be improved, but the difficulty of operation and team maintenance increases
Solution Approach 1:
The patent implements self-service capabilities where the testing framework automatically provides protocol knowledge, message validation rules, and state transition logic without requiring human experts to maintain this knowledge. The system itself manages protocol specifications and updates, performing self-validation and self-correction, which maintains testing depth while reducing the burden on the testing team.
Data Source
AI summary
A method for testing network interaction defines a set having a plurality of network nodes, wherein the network nodes within the set are in signal communication with each other and wherein at least one of the network nodes is emulated by a processor. A set of transactions between network nodes is defined by repeated steps of defining a request message for message transfer between at least a first node and a second node; and defining, for each request message, at least one corresponding response message for transfer between the second node and the first node. The method executes the defined set of transactions and tracks and records performance data from the set of network nodes participating in the set of transactions, and displays the recorded performance data.
