How long does it take to send a file of 640,000 bits from host A to host B over a circuit-switched network?
all link speeds: 1.536 Mbps
each link uses TDM with 24 slots/sec
500 msec to establish end-to-end circuit
end2end + filesize/rateSlice
end2end = 500/1000
filesize = 640,000/(1024*1024)
"rateSlice" = 1.536/24 (lo que se trasmite por segundo o "ancho de banda") son 67.108.864 bits por segundo
500/1000 +640,000/(1024*1024)/(1.536/24) = 0.50000953674
