1. The figure shown below is about "Setup Request" in a virtual circuit network. In this figure, the source A sends a setup frame to switch 1. Then, the 1* switch acts as a packet switch which only knows the incoming virtual circuit identifier (VCI] but does not know the outgoing VCI yet. The 2d and the 3 switches do the same as the 1t switch Port IVCI Port VCI-77 Switch 1 Switch 3 Switch 2 Pot VCI Port The next figure is about "Setup Acknowledgement Here, the destination B sends an acknowledgment to the 3 switch and the empty spot of the forwarding table is filled. Then, the 2nd and the 1st switches do the same as the 3 switch. Your task is to simulate "Setup Request" and "Setup Acknowledgment" using a set of programing codes. If you are not able to write a set of programming codes, you may write a pseudocode (50 points). 14 VCI-77 Switch 1 Switch 3 Swiich 2 Pont VCI Por 1.
