Hi mate

i need o do a python program to connect 2 systems using TCP/IP and
UDP. Also i need to check the performance of these two protocols (how
many bytes received and how much time took). I havent worked in python
earlier and have no idea of this. Could someone pls help me. I created
a program which can connect between 2 systems using these UDP and TCP/
IP protocols. I dont know how to check the rest like how many bytes
send or how much time taken
since this is part of my course work could someone please help me
thanks in advance.

Sorry to diverge from the topic, but is there a reason you need to
develop something like again? I would assume that there would be
numerous utilities that would do this for you.

If you want these features in your applications, why don't you
consider incorporating existing tools/libraries into your program.

Just trying to reason why you would want to write a network metrics
program over again.

So you want to write a program using sockets then?

http://docs.python.org/lib/module-s...

Have a look at the time or timeit modules.

The standard library documentation, while lacking in some areas, is
very much your friend here:

From http://docs.python.org/lib/socket-ob... (emphasis mine)
send(string[, flags])
Send data to the socket. The socket must be connected to a remote
socket. The optional flags argument has the same meaning as for recv()
above. *Returns the number of bytes sent.*

recv(bufsize[, flags])
Receive data from the socket. The return value is a string
representing the data received.

For timing you can probably use the timeit module (http://
docs.python.org/lib/module-timeit.html) but I'm not really sure how
you're defining "performance". I mean, I can already tell you that
overall UDP will be "faster", as it has much less overhead. Surely
your course has covered this...

It's obvious, isn't it?
