Remote IP Address Allocation via Detection Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current networking methods fail to enable clients to automatically obtain maintenance IP addresses allocated by remote servers, leading to inefficiencies in IP address management and configuration.
Innovation Solution
A method and apparatus utilizing a Remote Host Configuration Protocol (RHCP) to transmit detection IP packets with allocated IP addresses through an access router, allowing clients to obtain and configure temporary and formal maintenance IP addresses, with the option to further utilize DHCP for address allocation and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a client is connected to an access router through PPP interface for networking, then the client can communicate with remote servers through the access router, but the client cannot automatically obtain the maintenance IP address allocated by the remote server
Solution Approach 1:
The patent introduces an intermediary mechanism (RHCP protocol and detection IP packets) between the client and remote server to enable automatic IP address acquisition. The remote server sends detection IP packets through the access router to the client, carrying maintenance IP address information, which resolves the contradiction by providing automated configuration while maintaining reliable delivery through the PPP interface architecture
Solution Approach 2:
The patent implements preliminary action by pre-configuring the access router with routing information mapping client identifiers to their respective network segments. This allows the access router to automatically forward detection IP packets from the remote server to the correct client through the PPP interface, enabling automatic IP address acquisition before the client needs to manually configure maintenance addresses
2Productivity
If manual configuration of maintenance IP address is used, then the IP address can be accurately assigned, but the network management efficiency is reduced and configuration complexity increases
Solution Approach 1:
The patent implements self-service by enabling clients to automatically obtain maintenance IP addresses through the RHCP protocol without requiring manual intervention. The remote server automatically sends detection IP packets containing maintenance IP address information through the access router to the client, which then configures the address automatically, thereby improving network management efficiency while reducing configuration complexity
Solution Approach 2:
The access router is pre-configured with routing information that maps client identifiers to network segments and PPP interface mappings. This preliminary configuration enables the automated IP address allocation process to function correctly without increasing operational complexity, as the router automatically performs the necessary packet forwarding and address assignment based on pre-established routing rules

AI summary
A method and an apparatus for obtaining a remote Internet Protocol (IP) address are provided. The method includes: receiving, by a first client, a first detection IP packet from a remote server through a Point to Point Protocol (PPP) interface, in which the first detection IP packet carries a first IP address allocated by the remote server for the first client; and configuring the first IP address to be an IP address of the first client. Through the method and the apparatus, the remote server is capable of allocating a remote IP address of a client.
