Assume an Internet phone application generates packets only during talk spurts.
During a talk spurt the sender generates bytes at a rate of 2,000 bytes per second. Every 40 msecs the sender gathers bytes into chunks.
Assume that RTP is used that will add a header to each chunk. In addition UDP and IP will be used.
Suppose all headers (including RTP, UDP and IP) have a total length of h and an IP datagram is emitted every 40 msecs.
Find the transmission rate in bits per second for the datagram generated by one side of the application.
