Telemetry Application in a Microburst Traffic Detection Scenario

Telemetry Application in a Microburst Traffic Detection Scenario

Traffic microbursts exist during network transmission. If a traffic microburst occurs, packets that exceed the device forwarding capacity are discarded. Devices then retransmit these packets, affecting the communication quality. The larger the number of microbursts, the poorer the network communication quality. Therefore, the NMS needs to monitor microbursts and adjust traffic in time.

Network traffic is generally measured based on the average traffic in 5 minutes and seems to be stable. However, at lower granularity levels, for example, millisecond level, many microbursts occur and cannot be perceived by SNMP get operations.

As shown in Figure 6-7, the traffic trend based on statistics queried in SNMP get mode is stable, and no network exception occurs. However, the traffic statistics reported in Telemetry mode show that microbursts occur. These microbursts can be detected using high-precision Telemetry sampling.
