How many users can circuit switching support?

How many users can be supported by circuit switching? Only R/r = 10 users can be supported. This is because in circuit switching, the maximum traffic rate of r = 100 kbps (kilobits per second) has to be allocated on the link for every individual user.

What is the maximum number of simultaneous connections that can be in progress at any time in this network?

4n connections
a) What is the maximum number of simultaneous connections that can be in progress at any one time in this network? We can have n connections for each of the links between the four pairs of adjacent switches. This gives a maximum of 4n connections.

What are the limitations of circuit switching?

Disadvantages of circuit switching:
• Great for only voice communication.
• Doesn’t use resources efficiently.
• Dedicated channels for circuit switching are unavailable for any other use.
• There is a higher cost to dedicate one channel per use.

Does packet switching support more users?

Packet switching allows more users to use network!

How many simultaneous users can be on one link in a circuit switched network?

ten simultaneous users
With circuit-switching, 100 Kbps must be reserved for each user at all times. Thus, the link can support only ten simultaneous users.

How much time elapses from the time a bit is created from the original analog signal at Host A until the bit is decoded as part of the analog signal at Host B )?

7msec
It converts the packet’s bit to an analog signal. How much time elapses from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B)? sec=7msec.

Would a packet switched network or a circuit switched network be more appropriate for this network Why?

Why? A circuit-switched network would be well suited to the application, because the application involves long sessions with predictable smooth bandwidth requirements. Since the transmission rate is known and not bursty, bandwidth can be reserved for each application session without significant waste.

How long does it take to send a file of 640 000 bits?

10 seconds
It takes 640,000 bits/64 kbps = 10 seconds to transmit the file.

What is circuit switching and packet switching?

Circuit switching and packet switching are the two different methods of switching that are used to connect the multiple communicating devices with one another. The key difference between circuit switching and packet switching is that packet switching is connectionless, whereas circuit switching is connection-oriented.

What is circuit switching in computer?

Circuit switching is a type of network configuration in which a physical path is obtained and dedicated to a single connection between two endpoints in the network for the duration of a dedicated connection. Ordinary voice phone service uses circuit switching. This reserved circuit is used for the duration of a call.
