Virtualization enables multiple networks, each customized for a particular purpose, to run concurrently over a shared substrate. One such model for managing these virtual networks...
Grid computations require global access to massive data stores. To meet this need, the GridNFS project aims to provide scalable, high-performance, transparent, and secure wide-are...
With the rapid growth of computer networks and network infrastructures and increased dependency on the internet to carry out day-to-day activities, it is imperative that the compo...
Progress in networking research depends crucially on applying novel analysis tools to real-world traces of network activity. This often conflicts with privacy and security requir...
In a recent work, we have shown that it is not possible to dependably build any type of distributed f fault or intrusiontolerant system under the asynchronous model. This result f...
