'''Circuit-switching''' was the approach used in the first generations of [[communication network]]s; they create a 'circuit' from one party to the other, with each switch along the path knowing about each circuit passing through them.

In the early circuit-switched networks, such as the early telephone network, the 'circuits' were actual [[analog]] physical [[circuit]]s (hence the name).

Later on, networks used for data tranmission used so-called 'virtual circuits'; in these networks, the switches that formed them knew about the virtual circuits passing through them.

This is fundamentally different from a [[reliable byte stream]] in a [[packet switch|packet-switching network]], where the switches ([[router]]s) have no idea about the byte streams which may be passing through them.
