Can you have multiple TCP connections on same port?

@FernandoGonzalezSanchez: A single client can have multiple TCP sockets bound to the same local IP/Port pair as long as they are connected to different remote IP/Port pairs. That is not specific to Windows, that is part of how TCP works in general.

What is TCP multicast?

Is TCP good for multicasting?

The TCP/IP protocol Stack is not compliant with the OSI model. In the TCP/IP stack this layer is actually called the internet layer. TCP requires the creation of a socket connection before data can flow. That is absolutely impossible with broadcast or multicast.
