===== Discussion =====

Packet Loss occurs when packets fail to reach the intended network destination or measurement point.

In the context of [[dido:99_annexes:annex-b-terms-and-definitions:i:internet_qos]], Packet Loss results from congestion, queue overflow, policing, transmission errors, routing failures, device failures, or deliberate discard policies.

===== Definition =====

//failure of packet-switched traffic to reach an intended destination or measurement point//

===== Source =====

Generalised from Internet QoS and IP performance terminology.

===== Note =====

Packet Loss is not message rejection, policy denial, data deletion, audit exclusion, or application-level validation failure.

===== Example =====

A congested router drops low-priority packets when its queue reaches the configured limit.
