Central Node Virtual Access Node Self-Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical access network devices require manual configuration, leading to increased complexity in managing large quantities of remote access nodes and fail to prevent invalid nodes from accessing the communications network.
Innovation Solution
A method where a central node receives a go-online notification from an access node, obtains configuration information, and sends it to the access node for self-configuration, reducing manual intervention and authenticating nodes to prevent unauthorized access.

Engineering Contradiction Analysis
1Manufacturing precision
If manual configuration is performed for each remote access node, then configuration accuracy is ensured, but device management complexity increases significantly when there are large quantities of access nodes
Solution Approach 1:
The access node performs self-configuration by automatically obtaining configuration information from the network side through authentication. The node configures itself without manual intervention, eliminating the need for operators to manually configure each device while ensuring accurate configuration through automated processes.
Solution Approach 2:
Configuration information is prepared in advance on the network side (authentication server) before the access node needs it. When the node comes online, it automatically retrieves the pre-prepared configuration information, eliminating the need for manual configuration at the node level.
2Ease of operation
If authentication is performed only on device user identity, then authentication process is simple, but invalid nodes cannot be prevented from accessing the network
Solution Approach 1:
The authentication process is segmented into multiple independent verification steps: first verifying the device user identity, then verifying the validity of the access node itself, and finally providing configuration information. This multi-stage approach enhances security while maintaining operational simplicity through automated processes.
Solution Approach 2:
An authentication server acts as an intermediary between the access node and the network. The server performs comprehensive authentication including node validity verification and provides configuration information, preventing invalid nodes from accessing the network while keeping the authentication process transparent and simple for users.

AI summary
The present embodiments relate to an information processing method, a network node, an authentication method, and a server. In one embodiment, a method includes generating a virtual access node corresponding to a first access node on a central node in response to determining that no virtual access node corresponding to the first access node currently exists on the central node; obtaining, by the virtual access node on the central node, configuration information related to the first access node; and sending, by the virtual access node to the first access node, the configuration information related to the first access node, after the first access node goes online.
