A Circuit-Switched network is connection oriented, vs a Packet-Switched network which is connectionless. In a C-S network, there must be a physical connection between the two hosts to communicate vs the P-S network which encodes the IP address at Layer3 of the OSI model (for TCP/IP) and the MAC address at Layer2 when the packet is encapsulated.

The physical devices (network interface card, router, switch, hub, etc.) use the MAC address to move the encapsulated packet from node to node until it finally reaches the node with the IP address that it was destined for or until the TTL (time to live) reaches zero in which case the packet is dropped.

An example of a connection oriented network might be a telephone system; you dial a number, the called number rings, if the phone is answered, the connection is set up and dialog takes place. Once the party(ies) hang up the connection is destroyed.

In a LAN, the computers are physically wired together (or can use wireless networking) but the computer can carry on multiple "conversations" at one time, streaming a video from one server while downloading a file from another server, etc. This is possible because the computer can and does interleave the packets over it's one and only LAN cable or wireless connection. This is in contrast to the telephone conversation in which the vast majority of the time there are only two parties on the line, the caller and called.

What is a difference between pstn and psdn?

PSTN stands for Public switched telephone network PSDN stands for Public switched Data network / Packet Switched Data Network. The basic difference between two is the switching technique used. PSTN uses Circuit Switching and PSDN uses Packet Switching


What type of switching does a network use?

circuit switching


What network technologies does not use circuit switching?

Ethernet does not use circuit switching, it uses packet switching.


Define circuit switching and packet switching what are the difference of them?

In circuit switching Networks,when establishing a call a set of resources is allocated for this call,and can't be used by any of the other calls.Packet switching main difference from circuit switching is that the communication lines are not dedicated to passing message from source to destination .In packet switching ,different message can use the same network resources with in the same time period .The major difference is that circuit switching statically reserves the required bandwidth in advance ,whereas packet switching acquires and releases it as it is needed


What is the difference between b-isdn and n-isdn?

B-ISDN is a circuit switching process. The N-ISDN is a virtual switching process (packets). ISDN stands for Integrated Service Digital Network.

What is a switching network?

There are three (3) ways to do switching: circuit switching, message switching, and packet switching. A network may employ 2 of these (message switching and packet switching) to send and receive data.


Advantages of circuit switching network over packet network?

Circuit switching has the following advantages Reliable Low latency which makes it faster with low error Circuit switching also has a guaranteed link with a reserved bandwidth between hosts. With circuit switching once the connection is established it can be accessed whenever needed. Versus with packet switching where resources are used on demand and can only transmit when it has access to the connection link.


Is cost of network is determined by circuit complexity?

switching complexity


What is circuit switching?

It is simplest form of switching which have dedicated physical path between sending and receiving. In circuit switching network,a set of switches are connected by physical link. A connection between the two stations is a dedicated path made up of one or more links.
