PFC STORM DETECTION AND PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18510315 titled 'PFC STORM DETECTION AND PROCESSING METHOD
Simplified Explanation
The present disclosure pertains to priority flow control (PFC) storm detection and processing methods. In one example method, a first network node detects PFC on a first port queue of a first port and determines that a preset condition is met. The preset condition involves detecting in N consecutive time segments, where in each segment, the quantity of PFC frames sent by the first port queue to a second network node exceeds a first threshold, while the quantity of data packets received from the second network node is below a second threshold. The PFC frame is used to signal the second network node to halt sending data flows in the first port queue, with N being a positive integer.
- PFC storm detection and processing methods are disclosed.
- The method involves detecting PFC in consecutive time segments.
- Conditions for PFC detection include thresholds for PFC frames and data packets.
- A PFC frame is used to instruct the second network node to suspend data flows.
- N is a positive integer representing the number of consecutive time segments.
Potential Applications
The technology can be applied in network management systems to prevent network congestion and ensure smooth data flow.
Problems Solved
1. Preventing network congestion. 2. Efficient management of data flow. 3. Timely detection and response to PFC storms.
Benefits
1. Improved network performance. 2. Enhanced data transmission efficiency. 3. Reduced chances of network downtime.
Potential Commercial Applications

Original Abstract Submitted
The present disclosure relates to priority flow control (PFC) storm detection and processing methods. In one example method, a first network node performs PFC detection on a first port queue of a first port, and determines that a first preset condition is met. The first preset condition includes: detection is performed in N consecutive first time segments, when the detection is performed in each first time segment, a quantity of first PFC frames sent by the first port queue to a second network node is greater than a first threshold, and a quantity of one or more data packets received by the first port queue from the second network node is less than a second threshold. The first PFC frame is used to indicate the second network node to suspend sending all data flows in the first port queue, and N is a positive integer.
