A stated objective of many initiatives toward an Information Infrastructure is to improve individual access, for example: provide advanced and “widely-accessible information services,” facilitate personal information processing, allow formation of virtual groups performing over distances, encourage broader use of information technologies, and promote personal skills development and training. Ho...

In this tutorial, we quantify resilience for an infrastructure system to a set of disruptive events in terms of degradation of system function. We show how to build and solve a sequence of models to assess and improve the resilience of an infrastructure system to those disruptions. Through simple examples and real-world case studies, we provide motivation, details of the models, and solution al...

This paper proposes to implement an IPv6 routing infrastructure as a self-organizing overlay network on top of the current IPv4 infrastructure. The overlay network builds upon a distributed IPv6 edge router with a master/slave architecture. We show how different slaves can be constructed to tunnel through NATs and firewalls, as well as to improve the robustness of the routing infrastructure and...

Creating a cost-effective large-scale multi-tier Enterprise service requires judicious selection and configuration of infrastructure elements and mechanisms. The minimum cost solution that satisfies business requirements for service availability and performance should be identified. Emerging self-managed computing utility environments demand an automated solution to this problem. This solution ...

We propose to use cloud computing for solving constraint programing problems in parallel. We used the Embarrassingly Parallel Search (EPS) method in conjunction with Microsoft Azure, the cloud computing platform and infrastructure, created by Microsoft. EPS decomposes the problem in many distinct subproblems which are then solved independently by workers. EPS has three advantages: it is an effi...

Due to many cyber attacks in the last years, governments are realizing how vulnerable they have become should there be a break out of a cyberwar. This urged them to establish a cyber warfare information infrastructure in a short time. However, this cyber warfare information infrastructure relies heavily on public infrastructures, like electricity and the Internet, which will be most likely targ...
