Automating Performance Diagnosis in Networked Systems
Diagnosing performance degradation in distributed systems is a complex and difficult task. Software that performs well in one environment may be unusably slow in another, and determining the root cause is time-consuming and error-prone, even in environments in which all the data may be available. …

Increasing the robustness of networked systems
What popular news do you recall about networked systems? You've probably heard about the several hour failure at Amazon's computing utility that knocked down many startups for several hours, or the attacks that forced the Estonian government web-sites to be inaccessible for several days, or you may …

Temporal synchronization of emulated and simulated models for assessment of networked systems
"Network experimentation practices rely on emulation or simulation methods to test new ideas. But it is difficult to exclusively simulate or emulate a broad class of emerging cyber-physical applications without incurring significant cost or loss of fidelity. This is because they involve complex …
