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.

Such a network might also need a command and control protocol for congestion management, adding even more complexity. To avoid all of these problems, the Internet Protocol allows for routers to simply drop packets if the router or a network segment is too busy to deliver the data in a timely fashion.
This problem has been the subject of much research. The consensus appears to be that the tail drop algorithm is the leading cause of the problem, and other queue size management algorithms such as random early detection (RED) and Weighted RED will reduce the likelihood of global synchronization, as well as keeping queue sizes down in the face of heavy load and unexpected peak traffic.
The two types of solutions are often complementary. The problem sometimes arrives with a combination of fast and slow network paths. Network solutions generally take the form of queue management algorithms. This type of solution has been the focus of the IETF AQM working group. [16] Notable examples include: Limiting the IP queue length, see ...
In computer networking, network traffic control is the process of managing, controlling or reducing the network traffic, particularly Internet bandwidth, e.g. by the network scheduler. [1] It is used by network administrators, to reduce congestion, latency and packet loss. This is part of bandwidth management.
Nagle's algorithm is a means of improving the efficiency of TCP/IP networks by reducing the number of packets that need to be sent over the network. It was defined by John Nagle while working for Ford Aerospace. It was published in 1984 as a Request for Comments (RFC) with title Congestion Control in IP/TCP Internetworks in RFC 896.
It is a reactive measure employed in communication networks to regulate network traffic and minimize bandwidth congestion. Bandwidth throttling can occur at different locations on the network. On a local area network , a system administrator ("sysadmin") may employ bandwidth throttling to help limit network congestion and server crashes. On a ...
