EXPORTING REAL TIME NETWORK TRAFFIC LATENCY AND BUFFER OCCUPANCY

摘要

Techniques are presented herein to facilitate the monitoring of occupancy of a buffer in a network device. Packets are received at a network device. Information is captured describing occupancy of the buffer caused by packet flow through the buffer in the network device. Analytics packets are generated containing the information. The analytics packets from the network device for retrieval of the information contained therein for analysis, replay of buffer occupancy, etc.

1. A method comprising:
at a collector device configured to be in communication with a network device operating in a network:
receiving analytics packets containing information describing occupancy of a buffer of the network device caused by packet flow through the buffer in the network device, each analytics packet including a record summarizing characteristics of a packet enqueued in the buffer or of a packet dequeued from the buffer; andreplaying the information pertaining to the occupancy of the buffer over time based on the analytics packets, by generating data for visually presenting to a user the information pertaining to the occupancy of the buffer over time.
