How to check the quality of data transfer using sockets and COM ports in Java?

Question

Java

Good evening!

How can I get a response from the receiving party about the quality of data transfer when transferring data from one program to another (Java), if the data is transferred: 1) using sockets, 2) using COM ports?

Answer 1

My programs: 1) data is transferred between 2 programs using sockets;

data transmission quality

speed

if your programs, then you just
collect statistics of received and sent data, on both sides, at some interval you
add packets with these statistics to the transmitted data protocol,
profit
ps By the way, it makes sense to transmit speed data only if there are more than two nodes (running applications), otherwise, this information on both nodes will be identical (the transmission speed on one node is equal to the reception speed on the other, it’s logical)
some kind of captain’s answer, it’s not clear why the author had such a question
