Over a packet$-$switched network, Host A sends Host B real$-$time voice data $($VoIP$).$ Host A$$s phone

converts analog voice to a digital $64$Kbps bit stream on the fly. Host A then packages $56$ consecutive

bytes at a time into packets. The optical fiber link that connects Host A to Host B has a transmission rate

of $2$Mbps and a length of $3000$km $($speed of light within the fiber, c$=3$x$108$m$/$s$).$ Assume that there is no

delay in packaging bits at Host A and no delay for Host B to decode packets as soon as they are received

back to analog signal.

$($a$)$ Assume only one packet is sent, what$$s the earliest and longest total times elapsed from the

time a bit is packaged at Host A until the bit is decoded at Host B $($assume Host B can decode

each bit as it is received without waiting for the entire packet for this problem$)?$

$($b$)$ Assume that Host A$$s voice data translates to $56$Kbytes, what$$s the total time elapsed from the

time all voice data is packaged at Host A until all the data is decoded at Host B$?$
