Circuit switching - Wikipedia, the free encyclopedia
In telecommunications, a circuit switching network is one that establishes a circuit (or channel) between nodes and terminals before the users may communicate, as if the nodes were physically connec...

Packet switching - Wikipedia, the free encyclopedia
Packet switching is a digital network communications method that groups all transmitted data, irrespective of content, type, or structure into suitably-sized blocks, called packets . The network ov...

TCP/IP networks were never designed to operate as circuit switched networks, which is the main reason why it has been difficult to implement QoS. But one interesting feature of the Internet is that it is largely an overlay to the circuit switched public telephone network infrastructure.

Circuit-switched is often contrasted with packet-switched. Some packet-switched networks such as the X.25 network are able to have virtual circuit-switching. A virtual circuit-switched connection is a dedicated logical connection that allows sharing of the physical path among multiple virtual circuit connections.

In my “grand overview” of networking, I describe networks as devices that are connected together using special hardware and software, ... In a circuit-switched network, before communication can occur between two devices, a circuit is established between them. This is shown as a thick blue line for the conduit of data...
