Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay , packet loss or the blocking of new connections.
The technical reasons for Internet bottlenecks are largely related to network congestion in which the user experiences a delay in delivering or accessing content. The bottlenecks can occur naturally, during high network use, or artificially created by owners of the network, generally considered to be ISPs, in order to prevent the network from ...
Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, [1] [2] or network congestion. [3]: 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.

Explicit Congestion Notification (ECN) is an extension to the Internet Protocol and to the Transmission Control Protocol and is defined in RFC 3168 (2001). ECN allows end-to-end notification of network congestion without dropping packets. ECN is an optional feature that may be used between two ECN-enabled endpoints when the underlying network ...
To put it another way, in case of network congestion any data flow is only impacted by smaller or equal flows. In such context, a bottleneck link for a given data flow is a link that is fully utilized (is saturated) and of all the flows sharing this link, the given data flow achieves maximum data rate network-wide.

In a data network, queuing delay is the sum of the delays between the request for service and the establishment of a circuit to the called data terminal equipment (DTE). In a packet-switched network, queuing delay is the sum of the delays encountered by a packet between the time of insertion into the network and the time of delivery to the address.
