Gateway-Based Zero-Touch Provisioning via Single Web Socket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large computer networks, manual provisioning of devices such as routers, switches, and gateways becomes impractical, requiring more efficient methods for configuration and communication.
Innovation Solution
Implementing a cloud-based provisioning system that allows network devices to connect via a single secure connection, leveraging a gateway as a central point for configuration downloads, reducing the number of individual connections to the cloud and optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each network device establishes individual secure connections to the cloud-based provisioning system, then each device can download its configuration independently, but the number of connections to the cloud increases dramatically, consuming excessive bandwidth and processing resources
Solution Approach 1:
The gateway acts as an intermediary between network devices and the cloud-based provisioning system. Devices connect to the gateway locally, and the gateway establishes a single secure connection to the cloud, mediating all provisioning communications. This eliminates the need for each device to connect individually to the cloud, dramatically reducing bandwidth consumption while maintaining provisioning capability.
Solution Approach 2:
Multiple individual device-to-cloud connections are merged into a single gateway-to-cloud connection. The gateway consolidates provisioning requests from multiple devices and communicates with the cloud through one unified secure connection, combining what would otherwise be numerous separate communication channels into a single efficient path.
2Ease of operation
If manual provisioning is used for each network device, then configuration control is maintained, but the process becomes nearly impossible when the network becomes very large
Solution Approach 1:
Network devices perform self-provisioning by automatically connecting to the gateway and downloading their configurations without manual intervention. The devices autonomously obtain their provisioning information through the automated ZTP process, eliminating the need for administrators to manually configure each device while maintaining centralized control through the cloud-based provisioning system.
Solution Approach 2:
Configuration templates and provisioning parameters are prepared in advance in the cloud-based provisioning system. When devices connect to the gateway, they automatically receive pre-configured settings and policies that have been predetermined by administrators, allowing scalable deployment without manual configuration of each individual device.
3Reliability
If multiple individual connections are maintained to the cloud, then each device has direct access to provisioning services, but the processing load on the cloud network increases significantly
Solution Approach 1:
The gateway serves as a mediator that handles all provisioning communications with the cloud, consolidating processing requests. Instead of the cloud system independently managing connections with dozens or hundreds of individual devices, the gateway centralizes these interactions, significantly reducing the processing load on cloud infrastructure while maintaining provisioning availability for all devices.

AI summary
Systems and methods are provided for configuring a plurality of network devices to connect to a cloud-based provisioning system via a single web socket connection. The connection may be established between the provisioning system and a first gateway that serves as the entry point to the Internet from a branch office. Other network devices may connect to this first gateway, including such as routers, switches, access points, and second gateways. The single web socket connection can dramatically reduce the number of connections that need to be established with the cloud-based provisioning system.
