What is exactly your question ?

Java is not the best environment for this kind of thing because it requires low level access to the OS. You can do it but you will find yourself jumping though hoops that are much more trouble then you need.

I recently made a post in another thread where I gave some links on how one might go about this. I don't know if this is indeed the direction you need to go, but this would be my first direction of inquery. I think that WMI can do what you need -- perhaps you could post a question to microsoft's scripting guys (they seem to be the WMI experts out there)

the Win32_PerfRawData_Tcpip_NetworkInterface class has BytesReceivedPerSec which sounds like the kind of thing you are interested in.

Here is a full example of how to use JACOB to query WMI to get information on the network usage statistics:

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.EnumVariant;
import com.jacob.com.Variant;


public class NetworkInterfaceQuery {
	/**
	 * List the network interfaces and thier statistics.
	 * 
	 * @param args
	 */
	public static void main(String[] args) {
		String host = "localhost"; //Technically you should be able to connect to other hosts, but it takes setup
		String connectStr = String.format("winmgmts:\\\\%s\\root\\CIMV2", host);
		String query = "SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface"; //Started = 1 means the service is running.
		ActiveXComponent axWMI = new ActiveXComponent(connectStr); 
		//Execute the query
		Variant vCollection = axWMI.invoke("ExecQuery", new Variant(query));
		
		//Our result is a collection, so we need to work though the.
		EnumVariant enumVariant = new EnumVariant(vCollection.toDispatch());
		Dispatch item = null;
		while (enumVariant.hasMoreElements()) { 
			item = enumVariant.nextElement().toDispatch();
			//Dispatch.call returns a Variant which we can convert to a java form.
			String BytesReceivedPerSec = Dispatch.call(item,"BytesReceivedPerSec").toString();
			String BytesSentPerSec = Dispatch.call(item,"BytesSentPerSec").toString();
			String BytesTotalPerSec = Dispatch.call(item,"BytesTotalPerSec").toString();
			String Caption = Dispatch.call(item,"Caption").toString();
			String CurrentBandwidth = Dispatch.call(item,"CurrentBandwidth").toString();
			String Description = Dispatch.call(item,"Description").toString();

			String Frequency_PerfTime = Dispatch.call(item,"Frequency_PerfTime").toString();
			String Frequency_Sys100NS = Dispatch.call(item,"Frequency_Sys100NS").toString();
			String Name = Dispatch.call(item,"Name").toString();
			String OutputQueueLength = Dispatch.call(item,"OutputQueueLength").toString();
			String PacketsOutboundDiscarded = Dispatch.call(item,"PacketsOutboundDiscarded").toString();
			String PacketsOutboundErrors = Dispatch.call(item,"PacketsOutboundErrors").toString();
			String PacketsPerSec = Dispatch.call(item,"PacketsPerSec").toString();
			String PacketsReceivedDiscarded = Dispatch.call(item,"PacketsReceivedDiscarded").toString();
			String PacketsReceivedErrors = Dispatch.call(item,"PacketsReceivedErrors").toString();
			String PacketsReceivedNonUnicastPerSec = Dispatch.call(item,"PacketsReceivedNonUnicastPerSec").toString();
			String PacketsReceivedPerSec = Dispatch.call(item,"PacketsReceivedPerSec").toString();
			String PacketsReceivedUnicastPerSec = Dispatch.call(item,"PacketsReceivedUnicastPerSec").toString();
			String PacketsReceivedUnknown = Dispatch.call(item,"PacketsReceivedUnknown").toString();
			String PacketsSentNonUnicastPerSec = Dispatch.call(item,"PacketsSentNonUnicastPerSec").toString();
			String PacketsSentPerSec = Dispatch.call(item,"PacketsSentPerSec").toString();
			String PacketsSentUnicastPerSec = Dispatch.call(item,"PacketsSentUnicastPerSec").toString();
			String Timestamp_Object = Dispatch.call(item,"Timestamp_Object").toString();
			String Timestamp_PerfTime = Dispatch.call(item,"Timestamp_PerfTime").toString();
			String Timestamp_Sys100NS = Dispatch.call(item,"Timestamp_Sys100NS").toString();

			System.out.println("Name = " + Name);
			System.out.println("BytesReceivedPerSec = " + BytesReceivedPerSec);
			System.out.println("BytesSentPerSec = " + BytesSentPerSec);
			System.out.println("BytesTotalPerSec = " + BytesTotalPerSec);
			System.out.println("Caption = " + Caption);
			System.out.println("CurrentBandwidth = " + CurrentBandwidth);
			System.out.println("Description = " + Description);
			System.out.println("Frequency_Object = " + Frequency_Object);
			System.out.println("Frequency_PerfTime = " + Frequency_PerfTime);
			System.out.println("Frequency_Sys100NS = " + Frequency_Sys100NS);
			System.out.println("OutputQueueLength = " + OutputQueueLength);

			System.out.println("PacketsReceivedDiscarded = " + PacketsReceivedDiscarded);
			System.out.println("PacketsReceivedErrors = " + PacketsReceivedErrors);
			System.out.println("PacketsReceivedNonUnicastPerSec = " + PacketsReceivedNonUnicastPerSec);
			System.out.println("PacketsReceivedPerSec = " + PacketsReceivedPerSec);
			System.out.println("PacketsReceivedUnicastPerSec = " + PacketsReceivedUnicastPerSec);
			System.out.println("PacketsReceivedUnknown = " + PacketsReceivedUnknown);
			System.out.println("PacketsSentNonUnicastPerSec = " + PacketsSentNonUnicastPerSec);
			System.out.println("PacketsSentPerSec = " + PacketsSentPerSec);

		} 
	}
}

The code is a little ugly because I just did some regex/replace - copy/paste work to get all of the elements that get returned.
