Network Question
-
Here is a question that one of my friend asked me but I haven't any answer for it. Then if you know the answer or if you have any idea, please reply: Assume that if layer K of Network Layers has an unreliable and connectionless service, then by adding some overload to (K+1) layer of Network Layers, we can make the service a reliable and connection oriented service. Now think reverse: Assume that the service of layer K is connection oriented, is it possible to have a connectionless services on layer (k+1)? Best regards, A. Riazi

Sure. Whenever the connectionless services layer is asked to transmit to a certain location, it can open a connection, transmit the data and close the connection again. It could work similarly for receive. If it was asked to receive on a certain port, it would listen for a connection, and when it got one would receive the data, close the listening port, and hand the data back to the application.

It's actually what happens in ATM networks (the most diffused WAN technology). On connection-oriented networks you always have the possibility to use UDP. Look here: ATM at Wikipedia[^] EDIT: Telecommunication Network Fundamentals lessons has been useful, finally! :-D ___________________________________ Tozzi is right: Gaia is getting rid of us.

I think not. Riazi is graduated. ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]

Dunno. It's your language. I just checked with google translations and I think it's correct. ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]
