ENROLLMENT NO. :- MUR2301340
COURSE :- MCA 2nd SEMESTER
3. IN THIS PRESENTATION WE WILL LEARN AND EXPAND OUR CONCEPTS ON THE TOPIC OF
‘CIRCUIT SWITCHING’. SO, BY THE END WE Will HAVE A SOLID UNDERSTANDING OF HOW CIRCUIT
SWITCHING ENABLES SYSTEMS TO RUN MORE EFFICIENTLY.
4. Circuit switching is a foundational technology for
telecommunications, used for establishing a dedicated
communication channel between two devices. It has
played a crucial role in the history of networking and
telephony.
Introduction to Circuit Switching
5. HOWCIRCUITSWITCHING WORKS
• Call Setup Process
When a call is initiated, a dedicated
circuit is established till the call ends.
• DataTransmission
Data is transmitted in a continuous
stream over the dedicated circuit.
• Fixed BandwidthAllocation
The bandwidth is reserved for the entire
duration of the call, ensuring consistent
quality.
• Resource Utilization
Each circuit remains dedicated
irrespective of the data flow, leading to
potential resource waste.
7. 1. Low Latency
Direct connection results in minimal delay and consistent data delivery.
2. Guaranteed Bandwidth
The dedicated circuit ensures a fixed and predictable bandwidth for the entire connection
period.
3. Security
Circuit switching provides inherently secure connections due to its dedicated nature.
Advantages
8. 1. Resource Inefficiency
Full utilization of resources occurs only during the call duration, leading to inefficiency during
idle times.
2. ScalabilityChallenges
Difficulties in scaling due to the need for dedicated resources for each connection.
3. Less Flexibility
Circuit switching is less adaptable to varying data transfer needs as the bandwidth is fixed.
Disadvantages
9. 1. EarlyTelephony
Used in traditional landline telephones for establishing voice calls.
2. Broadcasting
Historically utilized for live television broadcasts and radio transmissions.
3. Legacy Networks
Still employed in some legacy systems with specific requirements for dedicated connections.
Applications of Circuit Switching
10. EVOLUTION OF CIRCUIT SWITCHING TECHNOLOGIES
Analog Systems
Early circuit-switched
systems involved purely
analog technology for call
establishment and
transmission.
Digital Switching
Transition to digital systems
improved call quality and
efficiency in using network
resources.
IntegrationwithIP
Adoption of IP-based
technologies while retaining
circuit-switched principles for
certain applications.
