1. In the VoIP example in Section 9.3, let
h
be the total number of header byte added to each chunk, including UDP and IP header.

a. Assuming an IP datagram is emitted every 40 msecs, find the transmission rate in bits per second for the datagrams generated by one side of this application.

b. What is a typical value of
h
when RTP is used? How much time is required to transmit the header?
