You are evaluating a Voice over IP (VoIP) phone. The phone samples human
speech at 8,000 Hz using a 8-bit sample size to produce a voice bit stream (64
kbps). The phone must then packetize the voice stream for delivery to a peer
VoIP device. The phone will generate a packet for every 20ms of voice. Real-time
Transport Protocol (RTP, IETF RFC 3550) will be used to encapsulate the voice
data, which will then be encapsulated in UDP, then IPv4 (no options), and finally
Ethernet (18 bytes of overhead).
a) Draw a picture of this VoIP packet including all encapsulation layers, and label
sizes.
b) What is the ratio of overhead for a single VoIP packet?
c) What is the physical layer bitrate (kbps) for the VoIP flow?
d) What is the packet rate? (packets/second)
