Its also a stream of data, meaning that TCP takes care of splitting up your data into packets and sending those across the network for you.Īgain, remember its just like writing to a file. This connection is reliable and ordered, meaning that all data you send is guaranteed to arrive at the other side in the same order that you wrote it. This simply means that you make a connection between two machines, then you send data between the two computers much like you are writing to a file on one side, and reading from a file on the other. If you have ever used a TCP socket, then you’ll know that it is a reliable connection based protocol. Together they form the backbone for almost everything you do online, from web browsing to IRC to email, its all built on top of TCP/IP. TCP stands for “transmission control protocol” and IP stands for “internet protocol”. Once we have all this information, the correct choice becomes very clear! In light of the fact that we want to network an action game, we’ll take a very close look at the properties of each type of socket, and dig a bit into how the internet actually works. You know games like Halo, Battlefield 1942, Quake, Unreal, CounterStrke, Team Fortress and so on. So from this point on, and for the rest of this article series, I’m going to assume you want to network an action game. The choice you make depends entirely on what sort of game you want to network.

Do we use TCP sockets, UDP sockets or a mixture of both? When writing a network game, we first need to choose what type of socket to use. You have most likely heard of sockets, and are probably aware that there are two main types: TCP and UDP. Take care because if you get this part wrong it will have terrible effects on your multiplayer game! This is just the beginning – the simplest and most basic part of what network programmers do, but still it is quite intricate and non-obvious as to what the best course of action is. In this article we start with the most basic aspect of network programming, sending and receiving data over the network.
