NBD is fully transparent and does not require modification to the applications. NBD employs a novel technique called network flow distortion for bottleneck level estimation. The network connection states are all maintained throughout the operation of NBD. The NBD prototype has been shown to give accurate detection of network performance bottleneck and incur a mild performance overhead.
