Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quality detection technologies for physical networks are not suitable for cloud networks due to their flexible and changeable nature, making it difficult to accurately measure network quality in cloud environments.
Innovation Solution
A measurement system for cloud networks that includes a scheduling subsystem, measurement execution subsystem, and analysis subsystem, which perceives the measurement intent of a target tenant, generates a measurement rule, and uses bypass packet injection to collect measurement record information from network element devices, allowing for accurate network quality analysis without requiring complex measurement rule management or intrusion into the tenant's network environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing quality detection technology for physical networks is used, then the measurement process is simple, but it cannot accurately measure network quality in cloud networks due to flexible and changeable topology
Solution Approach 1:
The patent introduces network element devices as intermediaries between the measurement system and the cloud network. These devices receive measurement request messages, generate measurement record information, and return results without requiring direct access to tenant applications or complex interaction with the flexible cloud topology, thereby achieving accurate measurement while maintaining system simplicity
Solution Approach 2:
The measurement system is segmented into independent components: a scheduling device for generating measurement rules, network element devices for executing measurements, and an analysis device for processing results. This segmentation allows each component to perform its function independently, adapting to cloud network changes without requiring complex coordination between components
2Measurement precision
If complex measurement rule management is implemented, then measurement precision improves, but the burden on tenants increases and operation becomes more difficult
Solution Approach 1:
Network element devices automatically generate measurement record information in response to measurement request messages without requiring tenant intervention. The scheduling device automatically generates measurement rules based on measurement intents, and the analysis device automatically processes results, eliminating the need for tenants to manually manage complex measurement rules while maintaining high measurement precision
3Measurement precision
If measurement requires intrusion into tenant's network environment, then measurement precision improves, but reliability decreases due to potential interference with tenant applications
Solution Approach 1:
The measurement function is extracted from the tenant's network environment and implemented in dedicated network element devices. These devices generate measurement record information by processing measurement request messages without interfering with tenant applications, achieving accurate measurement while maintaining tenant network stability and reliability
4Ease of operation
If measurement is performed without actual application traffic, then ease of operation improves, but measurement precision may deteriorate due to lack of real traffic conditions
Solution Approach 1:
The system uses measurement request messages that copy the essential characteristics of actual application traffic without requiring real tenant applications. These synthetic measurement messages traverse the same network paths and are processed by the same network element devices, providing accurate network quality measurements under controlled conditions while maintaining operational simplicity

AI summary
A cloud network, a measurement system for the cloud network, and a method, a device and a storage medium. For a cloud network, by means of automatically perceiving a measurement intent of a tenant in the cloud network, generating a measurement rule that complies with the measurement intent, and delivering, on the basis of the measurement rule and by means of bypass packet injection, a measurement request message into network element devices on a path to be measured, a network quality analysis is performed with the help of measurement record information generated when the measurement request message passes through different network element devices.
