About This Document

This article provides solutions to Homework 1 of CIS 527 Computer Networks. It covers the calculation of bandwidth, RTT, delay x bandwidth product, and transmission time for LAN, point-to-point link, and switch. The homework includes three questions, and each question has a detailed solution with formulas and calculations. The first question is about calculating bandwidth for different packet sizes and distances. The second question is about calculating RTT, delay x bandwidth product, and transfer time for a point-to-point link. The third question is about calculating the total time required to transmit 10,000 bits from A to B as a single packet and as two 5,000-bit packets sent one right after the other.

CIS 527 – COMPUTER NETWORKSSOLUTION – HOMEWORK #11.(10 points) Consider a LAN with a maximum distance of 2 km. At what bandwidthwould propagation delay (at a speed of 2 x 108 m/s) equal transmit delay (insertiondelay) for 512 byte packets? What about 2000 byte packets?Solution:Case (a): Packet Size = 512 bytesMaximum Distance = 2 kmSpeed of Light = 2 x 108 m/sPropagation = Distance / Speed of Light = 2000 m / 2 x 108 m/sTransmit = Size / Bandwidth = 512 x 8 bits / BandwidthTherefore,Bandwidth = Size x Speed of Light / Distance= (512 x 8) bits x 2 x 108 m/s / 2000 m= 4096 x 105 bits / sec= 409.6 Mbits/secCase (b): Packet Size = 2000 bytesMaximum Distance = 2 kmSpeed of Light = 2 x 108 m/sPropagation = Distance / Speed of Light = 2000 m / 2 x 108 m/sTransmit = Size / Bandwidth = 2000 x 8 bits / BandwidthTherefore,Bandwidth = Size x Speed of Light / Distance= (2000 x 8) bits x 2 x 108 m/s / 2000 m= 16000 x 105 bits / sec= 1600 Mbits/sec
