kytkentävaihtoja
Kytkentävaihtoja, often translated as circuit switching, is a method of establishing a dedicated communication path between two devices before data transmission begins. This path, or circuit, is exclusively reserved for the duration of the communication session. Once the session is complete, the circuit is released. This is in contrast to packet switching, where data is broken into packets and sent independently through a network, sharing resources with other data transmissions.
The process of kytkentävaihtoja typically involves three phases: circuit establishment, data transfer, and circuit clearing. During
Historically, kytkentävaihtoja was the dominant technology for telecommunications, particularly in the public switched telephone network (PSTN).
