Circuit switching - Wikipedia, the free encyclopedia (549 words) |
 | In telecommunications, a circuit switching network is one that establishes a dedicated circuit (or channel) between nodes and terminals before the users may communicate. |
| Circuit switching can be relatively inefficient because capacity is wasted on connections which are set up but are not in continuous use (however momentarily). |
| Circuit switching contrasts with packet switching which splits traffic data (for instance, digital representation of sound, or computer data) into chunks, called packets, that are routed over a shared network. |

| This contrasts with the other principal paradigm, circuit switching, which sets up a dedicated connection between the two nodes for their exclusive use for the duration of the communication. |
| Circuit switched networks, such as the Public Switched Telephone Network (PSTN), also perform routing to find paths for circuits over which large amounts of data can be sent without continually repeating the complete destination address. |
| Packet switching influenced the development of the Actor model of concurrent computation in which messages sent to the same address may be delivered in an order different from the order in which they were sent. |
