Network Hardware API Integration for Secure Third-Party Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incorporating third-party hardware components into network devices often results in compatibility issues and requires extensive software updates, leading to downtime and increased costs for both manufacturers and customers.
Innovation Solution
A software development kit (SDK) is provided to third-party developers to create application programming interfaces (APIs) that allow secure access to network device resources, enabling rapid integration of third-party hardware without full software re-releases, thus reducing qualification and induction time to weeks instead of years.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If third-party hardware components are incorporated into network devices, then hardware functionality and versatility are improved, but software compatibility issues and integration complexity increase
Solution Approach 1:
The patent implements a universal software development kit (SDK) that provides a standardized set of application programming interfaces (APIs) and driver frameworks. This universal interface layer enables third-party hardware components from different manufacturers to be integrated into network devices without requiring custom software development for each hardware component, thus resolving the contradiction between hardware versatility and software integration complexity
Solution Approach 2:
The patent introduces an intermediary driver framework that acts as a mediator between third-party hardware components and the network device operating system. This driver framework translates hardware-specific operations into standardized commands, eliminating direct complexity between hardware diversity and software integration while maintaining compatibility across different hardware platforms
2Reliability
If conventional software validation and induction processes are used for new hardware components, then software reliability is improved, but qualification time and customer downtime increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring the SDK with standardized APIs, driver templates, and validation frameworks before third-party hardware integration begins. The software validation and induction processes are prepared in advance, allowing new hardware components to be quickly integrated and validated without requiring lengthy qualification periods, thus reducing customer downtime while maintaining reliability
Solution Approach 2:
The patent changes the parameters of the software validation process by implementing automated testing frameworks and standardized compliance checks within the SDK. These parameter changes transform the validation process from a manual, time-consuming procedure into an automated, efficient process that maintains reliability while significantly reducing qualification time from years to weeks
3Adaptability or versatility
If full software re-releases are performed to support new hardware components, then hardware support capability is improved, but manufacturing costs and customer upgrade requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the software system into modular components: the core operating system remains unchanged, while hardware-specific functionality is segmented into separate driver modules and SDK components. This allows new hardware support to be added through incremental driver updates rather than requiring full software re-releases, reducing manufacturing costs and simplifying distribution while maintaining hardware support capability
Data Source
AI summary
An example network device includes one or more hardware resources; a physical interface for receiving a hardware component; a memory; and one or more processors implemented in circuitry and configured to: receive the hardware component that has been coupled to the physical interface of the network device; receive data for an application programming interface (API) for the hardware component; store the data for the API to the memory; and execute the data for the API to grant the hardware component secure access to the hardware resources of the network device via the API. The hardware component may be an optical network interface. The resources may be raw registers of the network device. The processors may further tune the hardware component according to configuration for the network device, such as power management configuration for the network device, or the network device itself.
