Access Point Controller Discovery via Intermediary Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring cloud-based access-point controllers is cumbersome and time-consuming, especially for users with limited or restricted user interfaces, often resulting in errors and degrading the user experience due to the difficulty in identifying the associated controller.
Innovation Solution
An access point communicates with a configuration device via a network to request and receive the unique network address of a cloud-based controller, using an identifier such as a serial number, and associates with the controller based on the received information, simplifying the configuration process and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of access points is performed by users with limited interfaces, then configuration can be completed, but errors increase and user experience degrades
Solution Approach 1:
The access point performs self-configuration by automatically discovering and associating with the cloud-based controller using its identifier. The system eliminates the need for manual user configuration, allowing the device to configure itself autonomously through automated discovery protocols and identifier-based resolution.
Solution Approach 2:
The cloud-based controller is pre-configured with the access point's identifier (such as serial number or MAC address) before the access point needs to connect. This preliminary association data is stored in the controller, enabling automatic recognition and configuration when the access point initiates connection, eliminating manual setup requirements.
2Productivity
If users manually identify and configure cloud-based controllers, then association can be established, but time and complexity increase
Solution Approach 1:
The complex task of controller identification and selection is extracted from the user's responsibilities and transferred to the automated system. The access point extracts its own identifier and uses it to automatically resolve the appropriate cloud-based controller, removing the need for users to manually search, identify, and configure controller associations.
Solution Approach 2:
The access point's identifier (serial number, MAC address) serves as an intermediary that bridges the access point and the cloud-based controller. This identifier is used by the discovery mechanism to automatically resolve and establish the connection between the access point and its associated controller without requiring manual intervention.
3Adaptability or versatility
If cloud-based controllers are used instead of local controllers, then scalability and remote management improve, but discovery and association become more difficult
Solution Approach 1:
The cloud-based controller is pre-configured with the access point's identifier before deployment. This preliminary association ensures that when the access point is activated or reset, it can automatically discover the correct cloud-based controller through its identifier without requiring complex discovery protocols or user intervention.
Solution Approach 2:
The access point's unique identifier acts as an intermediary that enables automatic discovery of the cloud-based controller. The identifier is resolved through a discovery mechanism that translates the identifier into the controller's network address or endpoint, simplifying the discovery process despite the distributed cloud architecture.

AI summary
In order to configure an access point, the access point requests information specifying an associated cloud-based controller when the access point is first turned on at a user location. In particular, the access point may provide, to a configuration device, a controller query requesting information specifying a unique network address of a cloud-based controller associated with the access point. This controller query may include an identifier of the access point (such as a serial number). Then, the access point receives, from the configuration device, the information specifying the unique network address of the cloud-based controller, such as a fully qualified domain name of the cloud-based controller. Note that the cloud-based controller may be one of multiple cloud-based controllers from different providers, and the access point may be associated with the cloud-based controller based on the received information specifying unique network address.
