Packet Loss occurs when packets fail to reach the intended network destination or measurement point.
In the context of internet_qos, Packet Loss results from congestion, queue overflow, policing, transmission errors, routing failures, device failures, or deliberate discard policies.
failure of packet-switched traffic to reach an intended destination or measurement point
Generalised from Internet QoS and IP performance terminology.
Packet Loss is not message rejection, policy denial, data deletion, audit exclusion, or application-level validation failure.
A congested router drops low-priority packets when its queue reaches the configured limit.
