right now, I don't see the java have any existing information about statistic of network card is available, in java 5.0, use java.net.NetworkInterface will only give the general infomations about the each network card like IpAddress , MTU, MAC address etc.

I can't figure out how to calculate the speed of network card outside of jvm (in jvm is simple: total received bytes/ total system time) but you can call "netstat -s" from System.exec to get full view of network card statistics.
