ESE 548 Local & WAN Networks, Spring 2011, Prof. T.G.Robertazzi Project #1: Switching Element Problem To be submitted: Thursday, Feb. 24th 2011 Project Description In this project you will write a program to produce a discrete event simulation of a switching element with 10 inputs and 3 outputs as shown in Fig. 1. Time is slotted on all inputs and outputs. Each input packet follows a Bernoulli process. In a given slot the independent probability that a packet arrives in a slot is p and the probability that a slot is empty is (1– p ). One packet fills one slot. For a switching element if three or less packets arrives to some inputs, they are forwarded to the switching element outputs without a loss. If more than three packets arrive to the inputs of the switching element, only three packets are randomly chosen to be forwarded to the switching element outputs and the remaining ones are discarded. In your discrete event simulation the program will mimic the operation of the switch and collect statistics. That is, in each time slot

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
