[Solved]Q3 Packets Arriving High Speed Internet Backbone Router Observed Following Distribution 20 Q37127741
Q3. (a) Packets arriving at a high-speed Internet backbone router are observed to have the following distribution: 20% are voice packets of length 50 bytes, 50% are TCP acknowledgement packets of length 40 bytes, . . . 30% are FTP packets of length 5000 bytes. The packets arrive and depart over 25 Mbps connections, and the router is observed to have an arrival rate of 14 million packets in one hour. If all packets are initially placed in a single queue, determine the average delay experienced by any packet. [10 Marks] b) An Ethernet router has a single outgoing transmission link of 8 Mbps The average length of each packet is 960 bytes. If the average packet delay through the switch, is to be less than 18 ms, assuming an M/M/1 queue determine: [2 Marks] [4 Marks] 13 Marks] (ii) the maximum gross input packet rate to the switch in packets/s; (ii) the average length of the queue. (c) The maximum segment size in an Ethernet network is set to be 1492 bytes. A receiving node can accept up to 216 kBytes (64KB), after which time it performs a read operation from its buffer. If a 100kByte file of data is sent using TCP, determine how many acknowledgment (ACK) packets will be sent back to the sending node? (8 Marks] Show transcribed image text Q3.
