Network Testing System Synchronizing Multi-Protocol Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network testing methods face challenges in generating realistic and scalable test traffic to effectively evaluate the performance of packet switched networks, particularly in emulating complex user activities and synchronizing commands across different protocols and layers.
Innovation Solution
The solution involves a network testing system that defines and generates test traffic by emulating user activities across multiple protocols and layers, using a graphical user interface to synchronize commands and replicate user activities, allowing for the creation of an 'EU community' to simulate a large number of users and generate millions of packets, thereby mimicking real-world network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If test traffic is generated by emulating user activities across multiple protocols and layers, then the realism and accuracy of network testing is improved, but the device complexity and command synchronization difficulty increase
Solution Approach 1:
The test system is divided into multiple independent modules including a command generator, protocol layer modules (Layer 2-3 and Layer 4-7), and a test traffic generator. Each module handles specific protocol layers and can be configured independently, reducing overall system complexity while maintaining comprehensive testing capability across multiple protocols and layers
Solution Approach 2:
A command synchronization mechanism acts as an intermediary between the command generator and protocol layer modules. This mediator translates high-level user activity commands into synchronized protocol-specific commands across different layers, managing the complexity of multi-protocol coordination without requiring direct integration between all protocol layers
2Reliability
If synchronized commands are used to emulate user activities, then the reliability of network testing is improved, but the difficulty of detecting and measuring synchronization issues increases
Solution Approach 1:
The system incorporates a command synchronization mechanism that provides feedback between the command generator and protocol layer modules. This feedback loop monitors command execution status and timing across different protocol layers, automatically adjusting synchronization parameters to maintain reliable test traffic generation while making synchronization issues detectable through standardized status indicators
3Ease of operation
If a graphical user interface is used to define and generate test traffic, then the ease of operation is improved, but the productivity may be reduced due to manual configuration requirements
Solution Approach 1:
The system includes pre-configured protocol layer settings, command templates, and test traffic patterns that can be selected through the graphical user interface. These preliminary configurations reduce manual setup requirements while maintaining ease of operation, allowing users to quickly generate realistic test traffic by selecting from predefined options rather than configuring every parameter manually

AI summary
Methods and test systems for testing a network. A test system may emulate a plurality of users, each emulated user executing a user activity. Each emulated user activity may include one or more commands. At least some emulated user activities may include a first command associated with a first protocol synchronized with a second command associated with a second protocol different from the first protocol. The test system may report a result of emulating the plurality of users.
