Network / Server question
I am stress testing a Java server I've been working on during the last months and that is going to be used to create multiuser/multiplayer applications with Macromedi Flash.
Now, this may sound as the dumbest question ever, but I encountered one problem:
I run a test were a java client was using multiple threads to send lots of messages to the server. Basically the application logs in, joins a chat room and starts sending messages every 300 ms with 50-60 clients.
The peculiarity of the app is that it is not waiting for responses from the server and it does not read them from the socket connection, it just keeps banging the server.
The server receives all these messages and broadcast them to the other "virtual clients" and in no time the output socket of the server is completely full and the server stops sending any message
I know this is a very particular scenario, however this made me think that a hacker could try to do the same and flood the server (maybe using different clients) until he can't send anymore messages.
I am not sure if this is really possible and also how to prevent this. Any ideas ?
An anti flooding check would be a good idea, but I don't think it helps very much if the client on the other side does not read from the socket...
Bytheway the server uses NIO and it uses for output a blocking queue with multiple threads (I guess this is called a "Wrap")
Any suggestion would be highly appreciated :-)
