Bottleneck (network)

From Wikipedia, the free encyclopedia

A bottleneck point in computer networking is a node at which information is processed more slowly, or any element (a hard drive, I/O card or network interface card NIC) that slows network connectivity rates.

For example to reduce bottlenecks in the client-server model database, both server and client contribute to process SQL queries.

In a network, when every source has a bottleneck link, the allocation of rates is said "max-min fair"
