This OID shows the mean delay variation (average jitter) across all samples, expressed in microseconds. This metric smooths out random anomalies and tells you how 'jiggly' the link typically is; lower values mean more predictable latency. For example, a value of 1000 means on average, consecutive pings differed by 1 millisecond, which is acceptable for most applications, whereas 50000 would indicate an unstable link.
