1) Transmission delay(Tt): If there is a host and if it is having a data packet,the time taken by the host to put the data packet on to the outgoing link is called transmission delay.
L=1000bits Bandwidth=1Kbps what is Tt?
2) Propogation delay (Tp): Time taken by the single or one bit to reach from one end of the link to other link is called propogation delay.
factor on which propogation delay depands:
3) Queuing delay(Tq): Time taken to stay in queue before processing the last packet on receiver.
4) Processing delay(Tproc): Time taken to process next packet from queue to the processor on receiver end.
