Performance Analysis of Multi Tier Tree Topology for Time Synchronization

Implementation Plan:
—————————

Scenario 1: NTP under Baseline Network
————————————————-

Step 1: Initially, we constructed a multi-tier tree topology with 90 Ethernet switches and 1 Router node with Network Time Protocol (NTP) protocol.

Step 2: Then, we simulate and collect network data such as packet send/receive, packet size, transmission time, propagation delay, synchronization messages and clock timestamps

Step 3: Next, we analyze the NTP protocol network sectors to observe delay, offset, jitter, drift and synchronization stability behavior based on collected data.

Step 4: Finally, we plot performance for the following metrics:

4.1: Simulation Time (s) vs. Clock Offset (ms)

4.2: Simulation Time (s) vs. End-to-End Delay (ms)

4.3: Simulation Time (s) vs. Jitter (ms)
