Integrated Network Management Controller Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network controller architectures require separate devices for network and management controller functions, leading to increased complexity, cost, and power consumption, as well as the need for multiple physical interfaces for network and management traffic, which limits configurability and flexibility.
Innovation Solution
Integration of network controller and management controller functionalities into a single integrated circuit or logical entity, with shared host interfaces and sideband interfaces, allowing for unified management and network traffic handling without the need for separate devices or interfaces, enabling flexible configuration and reduced chip count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate devices are used for network controller and management controller functions, then device functionality is provided, but device complexity and component count increase
Solution Approach 1:
The patent combines network controller and management controller functions into a single integrated device. The network controller includes a processing unit that can execute both network control operations and management controller operations, eliminating the need for separate physical devices and reducing overall system complexity.
Solution Approach 2:
The processing unit in the network controller is designed to perform multiple functions - both network controller operations and management controller operations. This multi-functional approach allows a single device to replace what would traditionally require two separate devices, reducing component count while maintaining full functionality.
2Adaptability or versatility
If separate physical interfaces are used for network and management traffic, then traffic handling is provided, but device complexity and cost increase
Solution Approach 1:
The network interface in the integrated device is configured to handle both network traffic and management traffic through a single physical interface. The processing unit can identify and route different types of traffic through the same interface, eliminating the need for separate physical interfaces while maintaining full traffic handling capability.
Solution Approach 2:
The single network interface is dynamically configured to handle different types of traffic (network and management) based on the nature of the data being transmitted. The interface can switch between handling network control traffic and management traffic as needed, providing flexibility without requiring multiple dedicated physical interfaces.
3Reliability
If separate devices are used for network and management controllers, then dedicated functionality is provided, but power consumption increases
Solution Approach 1:
By merging network controller and management controller functions into a single device with a unified processing unit, the patent reduces the total power consumption of the system. Instead of two separate devices each consuming power independently, one integrated device performs all functions with shared resources, thereby reducing overall energy usage while maintaining dedicated functionality for both operation types.

AI summary
An network controller provides both network controller and management controller functionality. Accordingly, the system host sees, in a single device, both network functionality as well as management functionality. The integration may reduce chip count and provide a more cost effective as well as power efficient platform solution for the network and management functions in a larger system, such as a server with multiple network controllers and multiple network ports.
