CDN Management System with Centralized Node Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency of managing numerous Content Delivery Network (CDN) nodes dispersed across various locations due to reliance on manual on-site operations for tasks like power-on, shut-down, and OS management, leading to low management efficiency.
Innovation Solution
A CDN management system with a central controller and node controllers that enable remote management of service servers, using a centralized API module and processing module to generate and execute management tasks, allowing for outband and inband network management to avoid congestion and reduce the need for on-site manual operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual on-site operations are used to manage CDN nodes, then operational control is direct and simple, but management efficiency is very low due to the large number of dispersed nodes
Solution Approach 1:
The patent introduces a management system comprising a central controller and node controllers as intermediaries between operators and CDN nodes. The central controller receives task invoking requests, generates management tasks, and distributes them to appropriate node controllers, which then execute operations on service servers. This intermediary layer enables centralized management of hundreds or thousands of dispersed CDN nodes without requiring manual on-site operations, thereby dramatically improving management efficiency while maintaining operational control.
2Productivity
If centralized management is implemented across hundreds or thousands of CDN nodes in different locations, then management efficiency improves, but network infrastructure complexity and cost increase
Solution Approach 1:
The management system is segmented into two hierarchical levels: a central controller that handles high-level task invocation and coordination, and distributed node controllers that handle local task execution on service servers. This segmentation allows the system to manage hundreds or thousands of CDN nodes across different locations efficiently without requiring a fully centralized infrastructure, thereby reducing network complexity and cost while maintaining high management efficiency.
3Ease of operation
If remote management is implemented through centralized control, then on-site manual operations are reduced, but network bandwidth may be consumed for management traffic
Solution Approach 1:
The node controller acts as an intermediary that receives management tasks from the central controller and executes them locally on service servers. By caching management tasks and executing them locally rather than continuously communicating with the central controller, the system enables remote management capability while minimizing network bandwidth consumption. The node controller maintains local state and only communicates with the central controller when receiving new tasks or reporting status, thereby reducing network traffic.

AI summary
A content delivery network (CDN) management system is provided. The CDN management system includes: a central controller; and at least one CDN node. Each of the at least one CDN node includes: a node controller connected to the central controller, at least one service server, and a switch connected to the node controller and each service server. The central controller is configured to receive a task invoking request, generate a management task according to the task invoking request, and send the management task to the node controller, the task invoking request indicating a request to perform remote management on one service server of the at least one service server of the CDN node, and the node controller is configured to receive the management task sent by the central controller, and control the service server based on the management task.
