Introduction to Circuit Switching
Circuit switching is a telecommunications methodology that establishes a dedicated communication path between two endpoints for the duration of the transmission. This method ensures that a continuous and fixed bandwidth is allocated, making it particularly suitable for real-time voice and video communication.
In circuit-switched networks, such as traditional telephone systems, a connection is established before any data transmission occurs. A dedicated circuit is reserved solely for the parties involved in the conversation, which allows for uninterrupted data flow between them. This guarantees a consistent quality of service.
However, the circuit remains reserved exclusively for that connection, even during moments of silence or inactivity. This can lead to inefficiencies, as the allocated bandwidth may be underutilized when users are not actively transmitting data. Despite these limitations, circuit switching guarantees low latency and a predictable performance, making it ideal for applications requiring real-time data transmission.
Overall, circuit switching plays a vital role in established networks, particularly where reliable, continuous connections are essential. Understanding this method is crucial in comparing it with packet switching, which uses a fundamentally different approach to data transmission.
Packet Switching vs Circuit Switching: Key Differences
Packet switching and circuit switching are two fundamental techniques used in networking protocols, each enabling data transmission in distinct ways.
