Bluetooth SZTP Provisioning for Centrally Managed Network Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network devices often require manual configuration by non-expert users at remote sites, lacking necessary equipment and expertise, leading to inefficiency, security risks, and increased deployment costs due to misconfigurations and lack of centralized monitoring.
Innovation Solution
A combined approach using a Bluetooth® SZTP application and SZTP bootstrap server to provide initial configuration artifacts and redirect information, allowing network devices to self-provision securely and report progress to a central location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If DHCP or Bluetooth SZTP application is used exclusively for provisioning, then the provisioning process can be simplified, but centralized monitoring of provisioning status and real-time configuration capability are lost
Solution Approach 1:
The patent introduces a bootstrap server as an intermediary component that mediates between the network device and the provisioning system. The bootstrap server receives provisioning requests from network devices, generates configuration artifacts, and enables centralized monitoring of provisioning status while maintaining the simplicity of the Bluetooth SZTP application interface for end users.
2Productivity
If configuration artifacts are pre-generated, then provisioning can proceed without real-time configuration, but adaptability to different network scenarios and real-time configuration needs are reduced
Solution Approach 1:
The patent implements a dynamic configuration artifact generation system where the bootstrap server creates configuration artifacts in real-time based on the specific network scenario and device requirements. This dynamic approach allows the system to maintain fast provisioning speeds while adapting to different network environments, device types, and security requirements.
Solution Approach 2:
The system changes the parameters of configuration artifacts dynamically based on network conditions, device capabilities, and security requirements. The bootstrap server adjusts configuration parameters in real-time, enabling the system to optimize provisioning for different scenarios while maintaining operational efficiency.
3Manufacturing precision
If a capable laptop computer or specialized equipment is required for provisioning, then configuration accuracy can be improved, but deployment complexity and cost increase
Solution Approach 1:
The patent implements a self-service provisioning mechanism where the network device automatically communicates with the bootstrap server to obtain configuration artifacts. The system performs self-provisioning without requiring specialized equipment or expert intervention, thereby maintaining configuration accuracy through automated processes while eliminating the need for complex provisioning equipment.
Solution Approach 2:
The bootstrap server acts as an intermediary that provides centralized configuration management capabilities, enabling accurate and secure provisioning through a simplified interface accessible via common devices like smartphones or tablets running the Bluetooth SZTP application.
Data Source
AI summary
A method for provisioning a network device can include, on a network device in a factory-default state and having a factory-installed Secure Zero Touch Provisioning (SZTP) agent, enabling a wireless communication capability of the network device. Upon detecting the wireless communication capability being enabled, the SZTP agent attempts to establish a connection with an SZTP application on a computing device in close proximity to the network device. Once connected, the SZTP agent requests SZTP bootstrap information from the SZTP Application, receives SZTP artifacts, and determines whether the SZTP artifacts contain redirect information to an SZTP bootstrap server. If so, the SZTP agent validates the redirect information and attempts to connect to the SZTP bootstrap server. Once connected, the SZTP agent attempts to retrieve network device provisioning artifacts from the SZTP bootstrap server and provisions the network device using the network device provisioning artifacts retrieved from the SZTP bootstrap server.
