NS3 Simulation EXPOSED TCP Metrics You Never Knew
Understanding TCP Metrics Simulation in NS3
Time Interval: 00:00 - 06:14
Summary
🔄 TCP Data Transfer Simulation: The video explains how to simulate TCP data transfer between three network nodes (N0, N1, N2) using NS3. It outlines how the nodes connect through links with distinct bandwidth and delay.
🖥 NS3 Script Setup: Detailed steps are provided for setting up the NS3 script and modifying the parameters for simulations.
📊 Metrics for Analysis: The key TCP metrics discussed include average throughput, congestion window evolution, queue length over time, and queuing delay, which help analyze network performance under different conditions.
📝 Output and File Analysis: Running the script generates specific files like pcap logs and trace files, which contain critical data used to study TCP behavior.
🤔 Exercise Questions: The video presents questions to test understanding, such as evaluating throughput, analyzing congestion windows, and comparing different simulation results.
Bandwidth and Delay Values: The connection between N0 and N1 has a bandwidth of 10 Mbps with a delay of 100 ms, while N1 to N2 has a bandwidth of 7 Mbps with a 10-second delay. These parameters are vital for analyzing network behavior and performance.
Trace File Events: The simulation logs events like packet enqueue and dequeue times, providing insights into latency and congestion.
Performance Metrics: The video highlights calculating average TCP throughput and observing how the congestion window responds to network conditions, crucial for understanding TCP's efficiency.
