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)?
