Faster Distributed Systems Using Quasi-Synchrony
A way to organize distributed systems for data centers that require fewer resources and increase efficiency and predictability. Problem: Many distributed systems today are built on the assumption that the system is asynchronous - that packets can be lost or delayed arbitrarily and that clocks are at most weakly synchronized. This assumption results...

Methods, systems and computer readable media for detecting covert timing channels
Technology Overview: The method can detect covert timing channels by: 1. reproducing the timing of every network output; 2. comparing the observed timing to the reproduced timing; and 3. issuing an alert if there is any discrepancy. Penn researchers have built a time deterministic replay prototype called Sanity. It reproduces timing to within 2% on...
