Web-Server Farm Simulation with Load Balancing Using P2P Links Prompt used: Using NS-3 (C++), write a complete simulation file named farm.cc to be placed in the scratch/ folder and run with ./ns3 run scratch/farm.cc . Scenario: Simulate a web-server farm with load balancing using point-to-point links. The topology should have: 1 client node 1 load balancer node 3 backend web-server nodes All links are point-to-point (set data rate to 10Mbps, delay to 2ms) The load balancer distributes UDP traffic from the client across the 3 servers in a round-robin or equal-split fashion using OnOff applications Use UdpClientServerHelper or OnOffApplication + PacketSink on each server Enable NetAnim output ( animation.xml ) so the topology is visible in NetAnim with node labels (Client, LoadBalancer, Server1, Server2, Server3) Enable FlowMonitor and at the end of the simulation print per-flow stats (throughput, delay, packet loss) to the terminal A...
