Well what you've described is pretty much what a general denial of service flood is, although just one connection is never really going to be enough to do this, unless you have a lot of bandwidth at your disposal. This is why people go around infecting a lot of PC's, so they have hundreds of 1Mb/s and 3Mb/s connections and so on, that they can take full advantage of at any time and flood a server. So lets say just a random example, some guy has 100 infected computers that are able to dish out 1Mb/s. This is probably enough to perform a fairly reasonable attack on most dedicated servers, as most of them have a 100Mb/s connection.

The point of this type of attack is to take up all of the available bandwidth of the server, so that the legitimate clients who are trying to connect to the SA-MP servers hosted on the box are not able to get their traffic through, simply because all of the traffic is being taken up by the attacking networks. It doesn't actually cause the server software to crash or anything like that, it's just that you cannot access the server due to all of the available bandwidth being consumed.

There are other types of floods too, like syn floods, which attempt to take up all of the available ports on the system so that legitimate users cannot get a port allocated to them for transferring of data. This type of attack takes advantage of the SYN/ACK system the TCP protocol has in place.

There are also what I would call "DoS Exploits", which are basically denial of service attacks on a certain type of software that may be super effective because of a piece of bad coding or something. This means that more problems can be caused by less attackers and less bandwidth, in some cases a single client would be able to cause servers to crash. These however, are software related exploits, and are generally not the target of DDoS attacks.

I hope this information helps
