====== Network Congestion ======

[[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]

===== Discussion =====

Network Congestion occurs when offered traffic exceeds available forwarding, buffering, or transmission capacity.

In the context of [[dido:99_annexes:annex-b-terms-and-definitions:i:internet_qos]], Network Congestion increases latency, jitter, and packet loss unless traffic management mechanisms control the overload.

===== Definition =====

//network condition in which offered traffic exceeds available forwarding, buffering, or transmission capacity//

===== Source =====

Generalised from Internet QoS and packet-switched networking terminology.

===== Note =====

Network Congestion is not application overload, database contention, governance backlog, or DDS resource-limit exhaustion.

===== Example =====

A router experiences congestion when incoming packets arrive faster than the outgoing interface forwards them.
