Master-Slave IP Address Allocation via Sub-Segment Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP address allocation in master-slave networks experiences excessively long delays, leading to low communication efficiency due to the centralized management and unnecessary interactions in the allocation process.
Innovation Solution
The master device divides IP address segments into sub-segments and allocates them to slave devices, which can then directly allocate IP addresses to user devices using DHCP, reducing the need for level-by-level transmission and enabling dynamic reallocation and reclamation of IP addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the master device centrally manages all IP address allocation, then centralized control is maintained, but the allocation delay becomes excessively long
Solution Approach 1:
The patent segments the centralized IP address pool into multiple sub-segments and distributes them to different slave devices. Each slave device maintains a local DHCP server address pool for independent address allocation, eliminating the need for all requests to traverse to the master device. This segmentation directly reduces allocation delay while maintaining manageable complexity through modular distribution.
Solution Approach 2:
The patent introduces a hierarchical dimension to the IP address management system, where the master device operates at the top level for policy control and slave devices operate at the local level for execution. This dimensional restructuring allows simultaneous centralized oversight and distributed execution, reducing communication overhead and allocation time.
2Productivity
If the master device allocates IP addresses level by level through transparent transmission, then centralized control is maintained, but communication efficiency decreases
Solution Approach 1:
Slave devices are empowered to independently allocate IP addresses from their local DHCP server address pools without requiring continuous master device intervention. Each slave device autonomously handles address allocation requests from user devices within its management area, significantly improving communication efficiency and reducing allocation time while the master device focuses on high-level pool management.
3Loss of time
If slave devices transparently transmit DHCP requests to the master device, then centralized allocation is ensured, but unnecessary interactions increase delay
Solution Approach 1:
The patent extracts the DHCP server functionality from the master device and distributes it to slave devices. Each slave device maintains its own DHCP server address pool, eliminating the need for transparent transmission of allocation requests to the master device. This extraction reduces unnecessary interactions and delay while maintaining reliability through the master device's continued role in pool management and coordination.

AI summary
The present invention provides an IP address allocation method for a master-slave network, an apparatus, and a system. A master device generates an IP address sub-segment group, and separately sends at least one IP address sub-segment in the IP address sub-segment group to at least one slave device, so that the slave device can use a received IP address sub-segment as a DHCP server address and allocate an IP address to a user device. In this way, the slave device can directly allocate the IP address to the user device, so that an IP address allocation time is reduced.
