Please Answer Following Questions Calculated Expression Brief Description Element Calculat Q43886874
Please, answer the following questions: Each calculated expression and a brief description of each element in the calculation are needed. Solutions limited to final numerical values will not be considered correct. a) [10 pts] There are three packet switches between two hosts, the first link has a rate of R1 = 2 Mbps, the second link has a rate of R2 = 1 Mbps, and the third and fourth links have rates R3 = 3 Mbps and R4 = 4Mbps respectively (R2<R1<R3<R4). Assume there is no other traffic on this network, the processing delays are negligible. If every packet has size 64 bytes, what is the time needed to transfer 50 packets between these two hosts? b) [10 pts] Suppose there is a 10 Mbps microwave link between a base station on Earth and a geostationary satellite (approx. 36000 kilometers from Earth’s surface). Every minute the satellite takes a 24-bit RBG image (each pixel takes 24 bits), then sends it to the base station. If the propagation speed is 2 x 10^8 m/s. What is the propagation delay of the link? What is the size of this image file in pixels for the link to be continuously transmitting (continuous transfer would mean the next image file starts transmitting immediately after the previous image is finished transmitting)?
