How do I measure RTT and throughput in Java for some packets I need to send?
Yes please, that would be great.
First, you will need to initialize the DatagramSocket and bind it to a specific port. Then, you can use the DatagramPacket class to create the packet you want to send, and use the send() method to send it to the desired destination.
Once you receive the packet, you can get the timestamp using System.nanoTime() and calculate the RTT.
To measure throughput, you can calculate the amount of data sent and the time taken to send it, then divide the data by the time.
Does that make sense?
