- A Comparison of Software and Hardware Techniques for x86 Virtualization
- The x86 architecture has not yet permitted classical trap-and-emulate virtualization. Virtual Machine Monitors for x86, such as VMware Workstation and Virtual PC, have instead used binary translation of the guest kernel code. However, both Intel and AMD have now introduced architectural extensions to support classical virtualization. This paper compares an...

- Network Monitoring Using Traffic Dispersion Graphs (TDGs)
- Monitoring network traffic and detecting unwanted applications has become a challenging problem, since many applications obfuscate their traffic using unregistered port numbers or payload encryption. Apart from some notable exceptions, most traffic monitoring tools use two types of approaches: keeping traffic statistics such as packet sizes and inter-arrivals, flow counts,...

- On Optimal Probing for Delay and Loss Measurement
- Packet delay and loss are two fundamental measures of performance. Using active probing to measure delay and loss typically involves sending Poisson probes, on the basis of the PASTA property Poisson Arrivals See Time Averages, which ensures that Poisson probing yields unbiased estimates. Recent work, however, has questioned the utility...
