Microburst Detection

G8264 Command Reference for ENOS 8.4
Microbursts are short peaks in data traffic that manifest as a sudden increase in the
number of data packets transmitted over a specific millisecond‐level time frame,
potentially overwhelming network buffers. Microburst detection allows users to
analyze and mitigate microburst‐related incidents, thus preventing network
congestion.
