Unlike UDP, which is not flow controlled, TCP has congestion avoidance mechanisms that will Compare how TCP and UDP handle data transmission, focusing on their connection setups and suitability for various applications across networks. When establishing a TCP connect, you don't connect to (let's say HTTP) port 80 and get everything that came out (doing so will allow only one client at a time, terrible for user experience). I've been unable to play since a year ago, went over some posts and apparently the issue is something related to port forwarding. What you need to understand more than the similarities between TCP and UDP are the differences. Unless you can't use UDP for some reason, you should really avoid doing that.
