PR JarKom A Nama : Annisa Mutiafarha NPM : 0806334672 P5, P6, P7, P8, P9 P5. This elementary problem begins to explore propagation delay and transmission delay, two central concepts in data networking. Consider two host, A and B, connected by a single link of rate R bps. Suppose that two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/ sec. Host A is to send a packet of size L bits to Host B. a. Express the propagation delay, dprop , in terms of m and s d prop = m / s b. Determine the transmission time of the packet, d trans , in terms of L and R d trans = L / R c.Ignoring processing and queueing delays, obtain an expression for the end- to-end delay d = d trans + d prop = m / s + L / R d. Suppose host A begins to transmit the packet at time t = 0. At time t = dtrans , where is the last bit of the packet Host A e. Suppose dprop is greater than dtrans . At time t = dtrans , where is the first bit of the packet Jalur penghubung dari Host A ke Host B f. Suppose dprop is less than dtrans . At time t = dtrans , where is the first bit of the packet Host B g. Suppose s = 2,5 . 10 8 meters/sec, L = 100 bits, and R = 28 kbps. Find the distance m so that dprop equals dtrans d prop = dtrans

m / s = L / R m = L s / R m = (100 bits) (2.5 . 10 8 meters/sec) / (28 kbps) m = 8,9 . 10 6 meters = 8900 km P6. In this problem we consider sending real-time voice from Host A to Host B over a packets-switched network (VoIP). Host A converts analog voice to a digital 64kbps bit stream on the fly. Host A then groups the bits into 56-byte
