UDP multiple ports

[roccio]

Hello, I would like to know if it is possible to have two udp sockets receiving on two different port at the same ipaddress.

Thanks

[eXpl0it3r]

Yes, that's possible.

[roccio]

Ok, thank you.

Now I have another question for you masters

I would like to send a quite big image over the net as fast as possible (it must be runtime). I have it compressed so it's like 120K, what's the best method?

It's ok to use UDP (datagram limit) or better go to TCP?

I recommend reading about the differences between both protocols.

But, in general, a (simplified) rule of thumb:

If you need perfect replication of the data (ie: a file), you use TCP.
If not, you can use UDP.

Is it possible to mix UDP and TCP sockets?

Can I have one UDP socket and another TCP running at the same time?

[dabbertorres]

Of course, and is relatively common. For example, DNS uses both UDP and TCP (port 53).
