virtapiirikytkimet
Virtapiirikytkimet, also known as virtual circuit switches, are fundamental components in the architecture of telecommunication and computer networks, particularly in packet-switched networks. They enable the establishment of logical connections between endpoints, facilitating efficient and reliable data transmission. Unlike physical circuit switching where a dedicated physical path is reserved for the entire duration of a connection, virtual circuit switching establishes a temporary logical path. This path is identified by a virtual circuit identifier (VCI) that is maintained throughout the duration of the communication session.
When a connection is established, a virtual circuit is set up across the network. Each packet belonging
Common examples of technologies that utilize virtual circuit switching include Frame Relay and Asynchronous Transfer Mode
