Solution Overview
Problem
Conventional AI backend network systems lack adequate and efficient remote link failure management, leading to manual intervention and significant operational disruptions, downtime, and increased operational costs due to the scale and complexity of AI hardware components.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used for failure management in AI hardware, then operational costs and downtime increase, but system complexity and scale make automated management difficult to implement
Solution Approach 1:
The system enables self-service failure management where AI hardware components autonomously monitor their own health status, detect failures, and execute recovery operations without requiring manual intervention. The hardware-based management engine performs self-diagnosis and self-healing, transforming the system from passive to active self-management.
Solution Approach 2:
The system implements continuous feedback mechanisms where health status information is exchanged between AI hardware components through ACK packets containing health bits. This feedback loop enables real-time monitoring, automatic failure detection, and coordinated recovery actions across the distributed AI hardware system.
2Productivity
If hardware-based remote link failure management is implemented, then reliability and efficiency improve, but device complexity increases
Solution Approach 1:
The system merges failure management functionality directly into the AI hardware components themselves, combining monitoring, detection, and recovery operations within the hardware architecture. This integration eliminates the need for separate software-based management systems and reduces overall system complexity despite adding hardware capabilities.
Solution Approach 2:
The system replaces software-based failure management mechanisms with hardware-based implementations. The hardware-based management engine uses physical circuitry and dedicated hardware logic to perform failure detection and recovery operations, substituting the mechanical/software approach with a more efficient hardware-level solution.
3Ease of operation
If autonomous failure management is implemented with minimal software intervention, then operational costs decrease, but the complexity of hardware-based protocols increases
Solution Approach 1:
The system extracts failure management functionality from the main AI hardware operations and implements it as a dedicated hardware-based management engine. This separation allows the core AI computing functions to remain simple while the management operations are handled by specialized hardware circuits that autonomously monitor and respond to failures.
Solution Approach 2:
The system segments the failure management protocol into discrete, hardware-implemented components including health bit generation, ACK packet processing, and recovery decision logic. This segmentation enables modular hardware design where each component performs a specific function, reducing overall protocol complexity while maintaining autonomous operation.

AI summary
Methods, systems, and devices for providing remote link failure management using a remote link failure management engine of an artificial intelligence (AI) backend network system are described. Remote link failure management includes hardware-based techniques associated with AI hardware (e.g., an AI accelerator or AI System on Chip “SoC) where the techniques are employed to address malfunctions or breakdowns in components that facilitate the connectivity and communication between AI hardware and other components. The remote link failure management engine supports detecting, mitigating, and recovering from failures in the ports and links in AI hardware. In particular, remote link failure management can be provided for AI hardware based on an Artificial Intelligence Transport Layer Protocol (ATL). ATL enables adding a health bit in ATL data and ACK packets to exchange local port health status between a Sender device and a Receiver device, where the device is artificial intelligence Network Interface Controller (ANC).
