Universal Edge Gateway VNF Image Pre-Caching for Rapid Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing customer edge gateway devices require time-consuming and vulnerable large downloads of virtual network function (VNF) operating systems, which can lead to data corruption and inefficient use of hardware resources.
Innovation Solution
Pre-cache VNF operating system images on a separate, secure partition of the universal customer edge gateway device, allowing the device to select and instantiate the images locally without downloading from backend systems over the internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VNF operating systems are downloaded from backend systems during device instantiation, then the device can obtain the necessary software, but the download process takes a significant amount of time and is vulnerable to data corruption
Solution Approach 1:
The patent applies preliminary action by pre-caching VNF operating system images at the local cloud before the customer edge gateway device needs them. The local cloud stores ready-to-deploy VNF OS images, allowing the customer edge gateway device to access and instantiate VNFs locally without performing time-consuming downloads from backend systems during device instantiation.
2Loss of time
If VNF operating systems are pre-installed on customer edge gateway devices, then installation time is reduced, but hardware resources are wasted by storing software that may not be needed
Solution Approach 1:
The patent applies preliminary action by pre-caching VNF operating system images at the local cloud before the customer edge gateway device needs them. The local cloud stores ready-to-deploy VNF OS images, allowing the customer edge gateway device to access and instantiate VNFs locally without performing time-consuming downloads from backend systems during device instantiation.
Solution Approach 2:
The patent applies copying by creating a copy of the VNF operating system images and storing them at the local cloud. This allows the customer edge gateway device to access and instantiate VNFs from the local cloud copy without requiring the original images to be permanently installed on the device, enabling on-demand instantiation while reducing hardware resource usage.
3Reliability
If large VNF operating system files are downloaded over the internet, then the device obtains the necessary software, but bandwidth is consumed and data corruption risk increases
Solution Approach 1:
The patent applies preliminary action by pre-caching VNF operating system images at the local cloud before the customer edge gateway device needs them. The local cloud stores ready-to-deploy VNF OS images, allowing the customer edge gateway device to access and instantiate VNFs locally without performing time-consuming downloads from backend systems during device instantiation.

AI summary
This disclosure describes systems, methods, and devices related to staging a universal customer edge gateway device. A universal customer edge gateway device may generate, prior to deployment of the universal customer edge gateway device at a customer location, copies of virtual network function (VNF) operating system (OS) images on the universal customer edge gateway device, the copies including a first copy of a first VNF OS image and a second copy of a second VNF OS image; identify, during a deployment of the universal customer edge gateway device at the customer location, a selection of the first copy from a list of the copies; copy, during the deployment and based on the selection, the first VNF OS image to the universal customer edge gateway device; and instantiate, at the universal customer edge gateway device, the copied first VNF OS image.
