Difference between Circut Switched Networks and Packet Switched Networks
| Sr. No. | Topic | Circuit Switched Networks | Packet Switched Networks |
|---|---|---|---|
| 1 | Type of Network | Circuit-switched networks are connection-oriented networks. | Packet-switched networks are connectionless networks. |
| 2 | Definition | In this type of network, a dedicated route is established between the source and the destination, and the entire message is transferred through it. | In this type of network, the message is divided and grouped into a number of units called packets that are individually routed from the source to the destination. |
| 3 | Flexibility | Routs of the networks are inflexible in nature. | Routs of the networks are flexible in nature. |
| 4 | Resource Utilization | Once a route is established between the source and the destination, the route cannot be used by any other user. This leads to poor utilization of resources. | It allows simultaneous usage of the same channel by multiple users. This guarantees better resource utilization. |
| 5 | Reliability of Network | Circuit-switched networks are more reliable. | Packet-switched networks are less reliable. |
| 6 | Protocol types | It uses relatively simple protocols for delivery. | It uses relatively complex protocols for delivery. |
| 7 | Bandwidth Requirement | Bandwidth requirement is high in this type of network even for a low volume of data transmission. | Bandwidth requirement is less in this type of network because bandwidth usage wisely as a number of packets from multiple sources can be transferred via the same link. |
| 8 | Installation Cost | Installation cost is low in this type of network. | Installation cost is high in this type of network. |
| 9 | OSI Layer Working | It is present at the Physical layer. | It is present at the Network layer. |
| 10 | Modes Used | Time division switching and Space division switching. | Virtual circuit switching and datagram switching. |
| 11 | Chances of Congestion | Congestion can occur at installation time. | Congestion can occur at every packet level. |
| 12 | Delay | It may have a call setup delay. | It may have a Packet transmission delay. |
| 13 | Benefits | Dedicated routes ensure steady communication. | Flexible routes avoid network failures and provide better bandwidth coverage. |
| 14 | Drawbacks | Dedicated routes not usable for multiple data transmission. Hence, this leads towards the high bandwidth requirement. | Complex network structure and installation costs always remain high. |
| 15 | Usability | They are suitable for long continuous transmission, like voice calls. | They are unsuitable for applications that cannot afford delays in communication like high-quality voice calls. Hence, mostly used in data communication. |
