Extend the previous exercise. Estimate the size (in octets) of an IP datagram that carries one-quarter of a second of audio encoded in PCM, placed in an RTP packet, and encapsulated in UDP. (Hint: RFC 1889 defines the size of an RTP header.)
What will be an ideal response?
The commercial PCM produces 64,000/4 bps = 16,000 bps. We assume all these information
bits are sent as a single packet/datagram. RTP protocol adds 4x32 = 128 bits. The UDP adds 2x32 = 64
bits. And the IP adds 5x32 = 160 bits. So, the resulting IP datagram size will be 16,000 + 128 + 64 +
160 bps.
