How does Adobe Stratus work?

Question

I want to know How does Adobe Stratus work? to get an idea of how to do something like it on my own. So what net hack Stratus uses to work like it works?

Answer 1

A common hack used by P2P software is a method called holepunching. This is used to bypass NAT.

When a network uses NAT, you are unable to connect to a computer within the network, from outside of the network, thus making it impossible to make P2P connections.

Say you have two computers, A and B, located in different parts of the world, both behind NAT. To establish a P2P connection A and B will connect to a Stratus server. This connection will open a port in A and B's routers. The stratus server will know these port numbers and will share this information with A and B. A and B can then make a connection to each others open ports thus establishing the P2P connection.
