Network Congestion

Go up to Terms and Definitions

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

In the context of internet_qos, Network Congestion increases latency, jitter, and packet loss unless traffic management mechanisms control the overload.

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

Generalised from Internet QoS and packet-switched networking terminology.

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

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