this problem, we consider sending real-time voice from Host A to Host
B over a packet-switched network (VoIP). Host A converts analog voice
to a digital 64 kbps bit stream on the fly. Host A then groups the
bits into 56- byte packets. There is one link between Hosts A and B;
its transmission rate is 2 Mbps and its propagation delay is 10 msec.
As soon as Host A gathers a packet, it sends it to Host B. As soon as
Host B receives an entire packet, it converts the packet’s bits 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)?
