Ckt switching

Question

is the total time in ckt switching is more than the packet switching

Comments

i think circuit switching takes less time because in that we have dedicated path. but here it again depends if u chose direct path, 1 hop , 2hop , etc.

Answer 1

It depends. the total time in circuit switch is setup time + transmission time+ propagation delay + end up time.

while in packet switching it only take the transmission time and propagation delay . but transmission is done at every hope.
circuit switch is like connecting a lan between two computer while packet switching is like transfering data using the internet in between.
if the data is in a bulk. lan will be usefull while if it is a small packet then packet switch will be best.

My question still not answer.

Answer 2

The total time depends on the amount of data you want to send.

If the data is large enough,then

Circuit Switching Time: Circuit Setup Time+ Transmission Delay+ Propagation Delay+Tear Down Connection Time.

Extra Factor is: Circuit Setup Time & Tear Down Time

Packet Switching is Store and Forward Mechanism, so at every hop transmission and propagation delay time is included

Packet Switching Time: (No of HOP X Transmission Delay)+(No of HOP X Propagation Delay)

Extra Factor is: Number of Transmission and Number of Propagation.

Conclusion: 

For Circuit Switching:

If message size is very big, in compare to message transmission time the circuit setup+circuit tear down time is very less.

If message size is small, in compare to message transmission the setup time going to hurt the efficiency.

For Packet Switching:

If message size is very big, then for each packet transmission and propagation at every hop is going to be huge .

If the data size is small, compare to setup time, the transmission time is going be less in total.

So, the Total Time Depends on the size of the message .

Answer 3

In ckt switching transmission of pkt will be done by source only (since we have dedicated path ) . So overall processing time is less

Whereas in pkt switching transmission of pkt not only done by source but also intermediate router(since we don't have didcated path) .So overall processing time is high

Hence ckt switching takes less time as comapred to  pkt swithcing.

Answer 4

if nothing is given  then SIMPLY  Circuit switching takes more time bcz it needs three phases(connection estab+data transfer+connection termination) while packet switch needs only one phase(data transfer)
