Simulation Task 1: Hub Network (Submit answers to each question) 1. Create the following topology that consists of 4 PC and 1 Hub (this lab doesn't have specific.pka file, you will create a .pkt file for this task). Use the following table to assign IP address to hosts. Host IP address PC1 10.1.1.1 PC2 10.1.1.2 Network Mask 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 PC3 10.1.1.3 10.1.1.4 PC4 PC-PT PC4 PC-PT PC3 Hub-PT Hubo PC-PT PCO PC-PT PC1 2. from PC1 ping PC2, PC3, and PC4 3. Create 1 traffic flow using simple PDU from PC1 to PC4 4. Run the simulation and observe how the hub device forwards the message to the destination and how the reply from PC4 gets to PC1. Specifically, does the Hub forward the PDU to all hosts? What happened to PDU sent to hosts PC2, and PC3? 5. Add more PCs, create more flows, and then observe the network. 6. What do you think will happen if there too many messages being Sent over the network? Simulation Task 2: Switched Network (Submit answers to each question) 1. Replace the Hub on the previous topology by a switch and redo steps 2 to 6
