java question

Okay, I'm a java noob, but I need a serious answer please. How can I get data about current dl/ul speed, particularly on a non-java socket? (I wanna write myself some sort of a speed meter)
Any suggestions?

using com.java.language.package.io.network.stream.buffer.BufferedStreamFromTheNetwork;

BufferedStreamBufferFromTheNetworkInsideTheIOPackage buffer = new BufferedStreamBufferFromTheNetworkInsideTheIOPackage();
