Elastic Transport Path Control Under Centralized Cloud Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing cloud service systems, network control algorithms are operated by individual cloud instances, leading to degraded network quality for other tenants when data is sent regardless of network statuses, and network statuses such as congestion and latency are not accurately reflected.
Innovation Solution
A cloud management platform provides a configuration interface for tenants to input ETP configuration parameters, creating dedicated ETPs for cloud instances, and performs comprehensive network control to ensure data transport requirements are met while mitigating network impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cloud instance runs network control algorithm to send data regardless of network statuses, then the data transmission requirement of the tenant is met, but the network quality for other tenants is greatly degraded
Solution Approach 1:
The patent introduces a cloud management platform as an intermediary between cloud instances. The platform receives data from the first cloud instance, performs comprehensive network control algorithms considering overall network statuses, and forwards data to the second cloud instance. This mediator approach allows centralized coordination of network resources, ensuring that data transmission requirements are met while preventing any single tenant from degrading network quality for others.
Solution Approach 2:
The patent extracts the network control authority from individual cloud instances and concentrates it in the cloud management platform. By taking out the network control algorithm execution from the tenant's cloud instance, the system prevents tenants from making selfish routing decisions that would harm overall network quality, while still achieving their data transmission goals through the platform's coordinated control.
2Ease of operation
If the cloud instance runs local network control algorithm, then the tenant can control data transmission, but network statuses such as congestion and latency are not accurately reflected
Solution Approach 1:
The cloud management platform acts as an intermediary that has comprehensive visibility into network statuses across all tenants. It collects and processes network status information (congestion, latency, etc.) from various parts of the network, then uses this accurate information to make routing decisions. This resolves the limitation of local cloud instances that cannot accurately perceive overall network conditions.
Solution Approach 2:
The system implements feedback mechanisms where the cloud management platform continuously monitors network statuses and uses this information to adjust routing decisions. The platform receives feedback about network conditions from multiple sources and incorporates this into its control algorithms, ensuring that routing decisions are based on accurate, real-time network status information rather than local estimates.

AI summary
A cloud management platform provides a configuration interface, where the configuration interface is configured to obtain an elastic transport layer ETP configuration parameter input by a tenant. The cloud management platform creates, based on the ETP configuration parameter, a first ETP bound to a first cloud instance of the tenant, where the first ETP is configured to forward data from the first cloud instance to the cloud management platform. The cloud management platform performs network control on the data based on the ETP configuration parameter, and sends, based on a network control result, the data to a second ETP bound to a second cloud instance, where the second ETP is configured to forward the data from the cloud management platform to the second cloud instance.
