An audio codec generates 6 bytes of data every 20 msec. The data is transmitted by packets (every 20 msec.) using RTP over UDP over IP and finally over Ethernet. How long is each packer in bits? ____________ bits What is the header overhead in percent? _________% We desire the header overhead to be at most 70%. This can be achieved by combining the data of more than one packet into a single packet. However, the more packets we combine the longer the incurred delay is. Therefore, minimum number of packets combination is desired. What is the minimum number of packets’ data to be combined to achieve at most 70% header overhead? ______________ packets
