IP Address Management for Inter-Private Network Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the IoT era, connecting multiple private networks to form a closed network poses challenges in preventing IP address overlaps, especially when the number of connected devices reaches tens of thousands or millions, and existing solutions like global IP address translation result in delays.
Innovation Solution
An information processing method and system that utilize a network management device with a first management function to manage inter-private network communication, and a second management function within each private network to manage IP address resources, ensuring non-overlapping IP addresses for inter-private network communication by allocating specific IP address pools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If global IP address translation is performed to connect multiple private networks, then inter-private network communication is enabled, but communication delay increases
Solution Approach 1:
The patent segments IP address management into two distinct functions: a first management function that manages IP address allocation across multiple private networks, and second management functions in each private network that manage local IP address pools. This segmentation eliminates the need for global IP address translation by enabling direct routing between private networks using locally allocated IP addresses, thereby reducing communication delay while maintaining reliable inter-network communication.
2Adaptability or versatility
If multiple private networks are connected to form a closed network, then network coverage and connectivity are improved, but IP address overlap becomes difficult to prevent
Solution Approach 1:
The patent introduces a first management function as an intermediary that coordinates IP address allocation across multiple private networks. This intermediary maintains information about IP address pools in each private network and allocates IP addresses from appropriate pools to devices communicating across networks. This mediator approach enables expanded network connectivity while simplifying IP address management by centralizing coordination without requiring manual configuration or complex translation mechanisms.
