Solution Overview
Problem
The performance and administrative bottlenecks associated with traditional networks and storage in large cloud computing architectures, particularly in next-generation supercomputers and data centers, are significant due to the limitations of existing interconnection networks like InfiniBand (IB) technology.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional networks and storage are used in large cloud computing architectures, then system compatibility and ease of integration are improved, but performance bottlenecks and administrative complexity increase significantly
Solution Approach 1:
The patent introduces an intermediary translation layer that converts traditional network addresses (IP addresses, MAC addresses) into InfiniBand identifiers (GIDs, LIDs). This intermediary mechanism enables seamless integration between traditional networks and the InfiniBand fabric, allowing systems to maintain compatibility with legacy networks while achieving high-performance communication through the IB fabric without direct performance bottlenecks
Solution Approach 2:
The patent segments the networking function into distinct components: a translation layer that handles address conversion, a routing layer that manages packet forwarding between traditional networks and InfiniBand fabric, and a performance optimization layer that leverages InfiniBand's high-speed capabilities. This segmentation allows each component to be optimized independently, resolving the contradiction between compatibility and performance
2Adaptability or versatility
If data packets are routed through external networks for processing, then network flexibility and service accessibility are improved, but communication overhead and processing time increase
Solution Approach 1:
The patent adds a new dimension to network communication by implementing parallel processing paths: critical time-sensitive data can be routed directly through the high-speed InfiniBand fabric, while less time-sensitive data can use traditional network paths. This dimensional approach to routing allows the system to optimize for speed when necessary while maintaining flexibility for other scenarios, eliminating the time penalty associated with external network routing
3Productivity
If native data processing is implemented within the IB fabric, then performance and speed are improved, but system complexity and addressing requirements increase
Solution Approach 1:
The patent creates a universal addressing system that can handle both traditional network addresses and InfiniBand identifiers through a single translation and routing infrastructure. The routing tables and translation mechanisms are designed to be multi-functional, supporting IP addresses, MAC addresses, GIDs, and LIDs within a unified framework. This universality reduces the perceived complexity by providing a consistent interface for diverse addressing schemes while enabling high-speed native processing
Data Source
AI summary
A system and method can support data service address resolution in a network environment. An intermediate node can receive an incoming data packet from a source node, wherein the incoming data packet targets a destination node, and wherein the incoming data packet includes a global identifier for the destination node and a local identifier for the intermediate node. Furthermore, the intermediate node can obtain local addressing information for the destination node based on the global identifier for the destination node. Then, the intermediate node can send an outgoing data packet to the destination node based on the obtained local addressing information for the destination node.
