Physical-Layer Control Blocks for Fast Link-Down Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing link-down event management in network devices is inefficient due to the unavailability or inaccessibility of critical data, leading to prolonged troubleshooting times and potential device damage in data centers.
Innovation Solution
Implementing a method that encodes link-down events within control blocks using the physical layer of communication networks, allowing devices to proactively manage and respond to impending link-down events by transmitting and receiving operational codes (opcodes) to initiate appropriate actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional link-down event management is used, then troubleshooting can be performed, but response time is prolonged and critical data may be unavailable
Solution Approach 1:
The patent encodes link-down event information into control blocks at the physical layer before the actual link-down occurs. This preliminary encoding ensures that critical event data is captured and transmitted while still accessible, enabling faster troubleshooting response without waiting for post-event log collection.
Solution Approach 2:
The patent introduces control blocks as an intermediary carrier that transports link-down event information through the physical layer. This intermediary mechanism bypasses traditional software-based log collection methods, providing direct access to event data and eliminating delays associated with centralized software solutions.
2Ease of operation
If centralized software solutions are used for link-down management, then coordination is achieved, but system complexity and dependency increase
Solution Approach 1:
The patent enables each network device to independently encode and transmit its own link-down event information through control blocks at the physical layer. This self-service approach eliminates the need for centralized software coordination, reducing system complexity and removing single points of failure while maintaining proper event management.
3Productivity
If physical layer encoding is implemented, then response time is reduced and autonomy is enhanced, but encoding complexity increases
Solution Approach 1:
The patent utilizes existing control blocks in the physical layer that serve multiple functions - both their traditional data transmission role and the additional function of carrying link-down event information. This multi-functionality approach avoids creating entirely new complex encoding mechanisms while achieving faster event management.

AI summary
Systems, computer program products, and methods are described for efficient link-down management. An example transmitter detects an impending link-down event at the transmitter. Once detected, the transmitter encodes the link-down event within a control block. The encoded control block is then transmitted via a physical layer of the communication network to a receiver. Once the control block is transmitted, the transmitter then initiates the link-down event. An example receiver receives the control block via a physical layer of the communication network from a transmitter. Then, the receiver extracts, from the control block, an operational code (opcode) identifying an impending link-down event at the transmitter. In response, the receiver retrieves, from a database, a responsive action corresponding to the link-down event based on the extracted opcode and subsequently executes the responsive action.
