Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network equipment test devices lack the ability to easily specify and implement variable and realistic burst profiles for simulated network traffic, which is essential for testing network devices that encounter varying packet sizes and types in real-world networks.
Innovation Solution
A method and system for testing network devices using a variable traffic burst profile, allowing users to select and transmit simulated traffic types, transmission rates, and burst profiles, with a simulated traffic generator that automatically or manually selects and applies burst profiles to simulate realistic network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current network equipment test devices use fixed traffic rate and fixed time between packet transmissions, then the device operation is simple, but the traffic burst profile is not variable or realistic
Solution Approach 1:
The patent applies dynamics by transitioning from fixed traffic parameters to variable traffic burst profiles. The system dynamically adjusts packet transmission intervals and rates according to predefined burst patterns that simulate real-world network conditions, allowing the traffic generator to adapt its behavior over time rather than maintaining static parameters.
Solution Approach 2:
The patent implements parameter changes by modifying traffic characteristics such as packet size, transmission rate, and inter-packet intervals according to different burst profiles. The system can switch between multiple parameter sets representing different network scenarios (e.g., voice traffic, data traffic, video traffic) to create realistic variable traffic patterns for comprehensive device testing.
2Adaptability or versatility
If network devices are tested with standardized IMIX packet mixes, then the testing process is simplified, but the test may not reflect specific real-world network conditions for different devices
Solution Approach 1:
The patent applies segmentation by dividing the traffic generation system into modular components that can be independently configured. Different traffic types (voice, data, video) are segmented into separate profiles with specific parameter sets, allowing users to select and combine only the relevant traffic types needed for their specific testing scenario rather than using a fixed standardized mix.
Solution Approach 2:
The patent implements universality by creating a multi-functional traffic generator that can produce various standardized IMIX patterns as well as custom variable burst profiles. The system is designed to handle multiple traffic types and patterns through a unified interface, making it adaptable to different testing needs while maintaining ease of configuration through standardized profile selections.
