Hello Hosein,

To measure UDP and TCP/IP delay, throughput, jitter, and loss ratio in Simulink:

1. Delay: Use the Time Scope block to observe the time taken for packets to travel from source to destination.Calculate delay by measuring the time difference between packet send and receive times.
2. Throughput: Use the Signal Statistics block to measure the number of bits transferred over a period. Calculate throughput as: Throughput (bps) = Total bits received / Total time (seconds)
3. Jitter: This is the variation in packet arrival time. Use the Difference block to compute the difference between consecutive packet arrival times. Analyze the variability using the Statistics block.
4. Loss Ratio: Use a Counter block to count packets at both sender and receiver ends. Calculate packet loss ratio as: Loss Ratio = (Packets Sent - Packets Received) / Packets Sent
