P7. In 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)?
