Key Concepts

Asynchronous Transfer Mode (ATM)

ATM is a high-speed networking technology that transfers data in fixed-size cells, which allows it to handle different types of traffic (voice, video, and data) simultaneously. It effectively integrates the benefits of both circuit switching and packet switching by establishing virtual channels that can be dynamically and permanently maintained, making it suitable for a wide range of applications.

Circuit Switching

Circuit switching involves establishing a dedicated communication path between endpoints for the entire duration of a connection. In ATM, the concept is adapted through virtual circuits, where paths are set up either temporarily or permanently, resembling traditional circuit-switched networks while utilizing the efficiency of cell-based packet transmission.

Switched Virtual Circuit (SVC)

SVC refers to a dynamically established virtual circuit that is set up only for the duration of a session. In ATM networks, SVC provides the flexibility of establishing a connection on demand, catering to temporary communication needs and allowing network resources to be used only when necessary.

Permanent Virtual Circuit (PVC)

PVC is a pre-configured virtual circuit that remains continuously available, providing a stable and dedicated connection between endpoints. In ATM, PVCs are used for consistent and long-term communication requirements, ensuring a reliable and always-on pathway without the need for repeated setup procedures.
