REAL TIME AND HIGH RESOLUTION BUFFER OCCUPANCY MONITORING AND RECORDING

摘要

Presented herein are techniques for monitoring the contents of a network buffer in a network device. An occupancy level of the buffer is sampled at a sampling rate. Occupancy levels of the buffer over time are determined from the sampling. Micro-second scale congestion events that have occurred in the network device are detected. An indication of the severity of the detected micro-second scale congestion events is generated.
