Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing large corporate networks with numerous endpoint nodes and subnets is complex and time-consuming, especially for service providers, due to continuous changes in IP ranges, leading to costly and burdensome manual table updates and inefficient content delivery.
Innovation Solution
A method and device that categorize endpoint nodes into sites by tracing routes through routing nodes and comparing information to identify common routers, automatically creating IP ranges and facilitating efficient content delivery and network management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tracking of IP ranges is performed for each subnet, then network management accuracy is maintained, but the complexity and time consumption increase significantly
Solution Approach 1:
The system performs self-service by automatically discovering and tracking IP ranges through route tracing operations. Instead of requiring manual intervention to maintain IP range tables, the network management system autonomously queries routing nodes, collects route information, and updates site categorizations without human input, thereby maintaining accuracy while reducing operational complexity
Solution Approach 2:
The invention changes the approach from static manual IP range tables to dynamic route-based categorization. By using route tracing parameters and comparing routing paths to endpoints, the system automatically adapts IP range assignments based on current network topology, eliminating the need for manual updates while maintaining precision
2Loss of information
If manual updates of IP range tables are performed continuously, then accurate site information is maintained, but the time and resources required increase
Solution Approach 1:
The system performs preliminary route tracing and site categorization actions proactively before services require this information. By continuously discovering endpoint sites and categorizing them in advance, the network management system ensures accurate IP range tables are ready when needed, eliminating the need for reactive manual updates and reducing time loss
Solution Approach 2:
The invention implements continuous automatic route tracing and site discovery operations that maintain up-to-date site information without interruption. This continuous useful action replaces periodic manual updates, ensuring information accuracy is maintained constantly without the time and resource overhead of manual intervention
3Measurement precision
If route tracing is performed for all endpoint nodes, then accurate site categorization is achieved, but the network traffic and processing load increase
Solution Approach 1:
The system applies partial action by performing route tracing for a selected number of routing nodes closest to each endpoint rather than tracing the entire path to the core network. This partial tracing approach achieves sufficient site categorization accuracy while significantly reducing the network traffic and processing load compared to complete route tracing for all endpoints
