Gateway Address Resource Management via Delegated Pools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for managing address resources in gateway devices lead to excessive horizontal traffic between multiple devices, resulting in wasted port resources and deteriorated system performance due to the need for numerous horizontal tunnels.
Innovation Solution
A method and gateway device that allocate delegated addresses only to user terminals within the same user group, reducing the requirement for horizontal tunnels and conserving port resources by managing address resources through a management gateway device that delegates exclusive address pools to specific gateway devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If horizontal tunnels are established between multiple gateway devices to ensure unity of traffic paths, then address resource management is achieved, but port resources are wasted and system performance deteriorates
Solution Approach 1:
The patent introduces a management gateway device as an intermediary that centralizes address pool management. Instead of establishing horizontal tunnels between all gateway devices, the management gateway device acts as a mediator that allocates and manages address pools, eliminating the need for complex peer-to-peer tunneling while maintaining traffic path unity through centralized control
2Productivity
If multiple gateway devices are deployed on the same site to expand network access capacity, then network service capability is improved, but address resource management complexity increases
Solution Approach 1:
The patent merges the address resource management functions of multiple gateway devices into a single management gateway device. This consolidation allows multiple gateway devices to operate independently for network access while their address management is unified through the management gateway device, reducing overall system complexity while maintaining expanded capacity
3Quantity of substance
If address pools are shared across multiple gateway devices to improve address utilization, then address resource efficiency is enhanced, but horizontal traffic increases
Solution Approach 1:
The patent segments address pools into dedicated portions allocated to specific gateway devices by the management gateway device. Instead of allowing all gateway devices to access all address pools (which creates horizontal traffic), the address space is segmented and assigned, enabling efficient utilization while minimizing unnecessary horizontal traffic between devices

AI summary
Embodiments of the present invention disclose a method and a gateway device for managing an address resource, which relate to the field of Internet technologies and can maximally reduce horizontal traffic between gateway devices, thereby improving system performance. The method in the present invention includes: sending an address delegation request message to a management gateway device in a same gateway group, where the management gateway device is configured to manage an address pool(s) or an address in an address pool; receiving a response message sent by the management gateway device, where the response message includes a delegated address, and the delegated address is an address in the address pool(s) managed by the management gateway device; acquiring the delegated address in the response message; and allocating an address in the delegated address to a user terminal in a same user group. The present invention is used for managing the address resource.
