Network Access Device Verified IP Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network connection methods involving terminal devices and network access devices often experience failures due to the inefficiencies and high message redundancy in obtaining and verifying IP addresses, leading to lower success rates and efficiency in establishing network connections.
Innovation Solution
A method and system where a network access device, equipped with a processor and a connection configuration component, authenticates terminal devices and generates verified IP addresses, which are then transmitted directly through a handshake protocol, reducing redundant communications and improving connection efficiency.

Engineering Contradiction Analysis
1Reliability
If conventional DHCP message interactions are used for IP address allocation, then the terminal device can obtain an IP address, but the connection process experiences high message redundancy and transmission failures
Solution Approach 1:
The network access device performs IP address verification and generates the verified IP address before the terminal device completes the connection handshake. This preliminary action eliminates the need for subsequent IP verification messages between the terminal device and DHCP server, reducing message redundancy and transmission failure points.
Solution Approach 2:
The IP address verification and generation function is extracted from the conventional DHCP interaction sequence and integrated into the network access device's authentication process. This separates the IP allocation function from the message-heavy DHCP protocol, reducing the overall message interaction complexity.
2Measurement precision
If multiple message interactions are used for IP address verification, then the IP address can be validated, but the connection process becomes less efficient
Solution Approach 1:
The network access device verifies IP address validity and generates the verified IP address in advance during the authentication phase. This ensures IP address validity through proactive verification while eliminating the need for multiple subsequent verification messages, thereby improving connection establishment efficiency.
Solution Approach 2:
The network access device performs self-verification of IP address validity using its own resources and capabilities, rather than relying on external DHCP server interactions. This self-service approach ensures accurate IP validation while reducing message overhead and improving connection efficiency.

AI summary
The present disclosure relates to network connection methods and devices for connecting a terminal device to a network through a network access device. The network access device may include a processor and a connection configuration component. The processor receives a connection request from the terminal device. The processor also authenticates the terminal device based on the connection request, and obtains a verified Internet protocol (IP) address from the connection configuration component. The processor further transmits the verified IP address to the terminal device after the terminal device is authenticated, wherein the terminal device is configured to be connected to the network by using the verified IP address.
