PXE Server Boot Approval Mechanism for Unknown Clients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OS boot image deployment systems fail to properly configure diverse computing devices and cannot efficiently handle unknown clients, leading to incorrect OS installations and inefficiencies in deployment processes.
Innovation Solution
Implementing a system where unknown clients are placed in intermediate storage for pending approval, allowing administrators or automated processes to review and approve or deny requests, ensuring correct OS image deployment by adding clients to a data store of known devices.

Engineering Contradiction Analysis
1Productivity
If the PXE protocol allows any server to respond to client requests, then the system is simple and fast, but incorrect OS images may be deployed to clients
Solution Approach 1:
The patent introduces an intermediary approval mechanism between the PXE server and client. When a client requests a boot image, the server checks if the client is in the approved list stored in database. If not approved, the request is held pending until an administrator or automated process approves it. This intermediary approval step ensures that only authorized clients receive OS images, preventing incorrect deployments while maintaining the rapid response capability of PXE.
2Productivity
If a standard OS image is deployed to all computing devices, then the deployment process is simple and efficient, but devices with different hardware configurations cannot be properly configured
Solution Approach 1:
The patent implements local quality by associating specific OS images with specific client identifiers in the approved list. Each client entry in the database can be linked to a particular OS image tailored to its hardware configuration. This allows different parts of the system (different clients) to receive customized OS images appropriate to their local hardware requirements, rather than using a universal image for all devices.
Solution Approach 2:
The system performs preliminary action by pre-configuring the approved list with client identifiers and their corresponding OS images before deployment begins. Administrators can pre-approve clients and associate them with appropriate OS images in advance, so that when deployment starts, the matching process is immediate and accurate, ensuring each device receives the correct image for its hardware configuration.

AI summary
Approving a client to boot in a pre-boot execution environment. A request is received from the client to boot the client by a computing device. The request includes device information associated with the client. A data store having a collection of known device information is queried in response to the received request. The request is stored, and it is determined whether to execute the received request by evaluating the device information in the stored request. The received request is responded to as a function of the evaluated device information.
