Consider sending real-time voice from host x to host y over a packet-switched network (voip). host x converts analog voice to a digital 32 kbps bit stream on the fly. host x then groups the bits into 64-byte packets. there is one link between host x and y; its transmission rate is 4 mbps and its propagation delay is 5 msec. as soon as host x gathers a packet, it sends it to host y. as soon as host y receives an entire packet, it converts that 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 x) until the bit is decoded (as part of the analog signal at host y)?
