Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional network traffic statistics collection systems face inefficiencies due to limited resources, requiring significant memory and processing power, and are cumbersome when switching between multiple message group contexts, leading to prolonged testing periods and resource constraints.

Innovation Solution

Implementing a system that generates and uses test messages with multiple context-specific message group identifiers (MGIDs) to enable efficient switching between active message group contexts during testing, allowing for continuous network traffic statistics collection without interrupting test message transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple message group contexts are tested using conventional systems, then comprehensive statistics can be gathered, but test reconfiguration and restarts are required which are cumbersome and inefficient

Engineering Contradiction:

Improveability to test multiple message group contextsVSAvoidoperational simplicity during context switching

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically switches between multiple message group contexts during a single continuous test by processing different MGIDs in test messages according to different contexts. The test system maintains multiple context configurations and activates them dynamically based on the MGID present in each test message, eliminating the need for static reconfiguration between tests.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The test system is designed to handle multiple message group contexts simultaneously within a single test framework. By incorporating multiple MGID fields in test messages and maintaining multiple context configurations, the system performs the function of testing different message groups without requiring separate test executions, thereby achieving multi-functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the number of MGIDs increases to cover more message groups, then more comprehensive statistics are collected, but the size of the statistics table and processing requirements increase

Engineering Contradiction:

Improvecoverage of message group statisticsVSAvoidstatistics table size and processing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the statistics collection by maintaining separate context configurations for different message groups. Each message group context has its own configuration parameters and statistics tracking, allowing the system to handle large numbers of MGIDs by organizing them into manageable contextual segments rather than a single monolithic table.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different context configurations are applied locally to different MGIDs based on their specific requirements. Each message group context can have customized parameters, filters, and statistics tracking tailored to its specific needs, rather than using a uniform approach for all MGIDs. This reduces overall complexity by optimizing each segment independently.

Inventive Principle:

Principle #3Local quality

3Productivity

If continuous testing is performed without interruptions, then testing efficiency is improved, but resource constraints on receive ports limit the ability to handle multiple contexts

Engineering Contradiction:

Improvetesting continuity and efficiencyVSAvoidavailable resources on receive port

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The system implements partial action by having the receive port process only the necessary portions of test messages relevant to the current active context. By selectively processing messages based on MGID matching and context activation, the system avoids the need for full resource allocation for all possible contexts simultaneously, enabling continuous testing within resource constraints.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Methods, systems, and computer readable media for network traffic statistics collection are disclosed. One method for network traffic statistics collection includes during testing of a system under test (SUT): receiving a first trigger message indicating a first message group context for statistics collection; receiving, from the SUT, a first test message of a plurality of test messages, wherein the first test message includes a first message group identifier (MGID) and a second MGID, wherein the first MGID is associated with the first message group context and the second MGID is associated with a second message group context; and performing, using the first MGID, statistics collection associated with the first message group context. The method may also include changing from the first message group context to the second message group context during the test and using the second message group context for statistics collection.
