Unified Network Interface Card for Multi-Protocol Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network interfaces in servers require multiple connectors and drivers for different types of network traffic, leading to hardware and software redundancies, inefficiencies, and increased costs due to proprietary interfaces and separate data and control paths.
Innovation Solution
A unified network interface system that combines multiple network traffic types into a single device using a shared Ethernet connector, processor, and driver, allowing for time-division-multiplexing and dynamic resource allocation, and eliminating the need for separate drivers and proprietary interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectors and drivers are used for different network traffic types, then network functionality and adaptability are improved, but hardware redundancy, device complexity, and costs increase
Solution Approach 1:
The patent implements a universal network interface card that can handle multiple network traffic types (Ethernet, Fibre Channel, InfiniBand, TCP/IP) through a single connector and unified driver architecture. The NIC is designed with multi-functionality to perform different networking functions without requiring separate dedicated hardware for each protocol type, thereby reducing hardware redundancy while maintaining adaptability
Solution Approach 2:
The patent combines multiple separate network interface functions into a single integrated NIC device. Instead of having separate connectors and drivers for Ethernet, Fibre Channel, and other network types, the invention merges these functions into one unified interface that can handle all traffic types through time-division-multiplexing and a single data path, eliminating hardware duplication
2Productivity
If separate data and control paths are used for different network traffic types, then traffic handling capability is improved, but device complexity and management difficulty increase
Solution Approach 1:
The patent merges separate data and control paths into a unified single data path that handles all network traffic types. The NIC processes different traffic types (storage, networking, interprocess communication) through this common path, eliminating the complexity of maintaining multiple separate paths while preserving full traffic handling capability through protocol-specific processing within the unified architecture
3Reliability
If proprietary interfaces and separate drivers are used for each network type, then protocol-specific performance is improved, but software redundancy and ease of operation worsen
Solution Approach 1:
The patent implements a unified driver architecture that provides universal support for multiple network protocols through a single driver interface. The NIC can handle Ethernet, Fibre Channel, InfiniBand, and TCP/IP traffic through this unified driver, eliminating software redundancy while maintaining protocol-specific performance through dedicated processing paths within the unified framework

AI summary
Systems and methods that network interface in a multiple network environment are provided. In one embodiment, the system includes, for example, a network connector, a processor, a peripheral component interface (PCI) bridge and a unified driver. The processor may be coupled to the network connector and to the PCI bridge. The processor may be adapted, for example, to process a plurality of different types of network traffic. The unified driver may be coupled to the PCI bridge and may be adapted to provide drivers associated with the plurality of different types of network traffic.
