Loss differentiation is recommended as a service differentiation provided by an Assured Forwarding (AF) Per-Hop Behavior (PHB) in Differentiated Service (DiffServ) architecture. An Active Queue Management (AQM) technique is addressed as a suitable alternative to realize the service differentiation because the AF PHB should attempt to minimize longterm congestion while permitting short-term cong...

High resilience military networks frequently have requirements for exchange of information with networks of low assurance, including networks of unknown threat such as the Internet. Traditionally, the approach to solving this problem is an air-gap between the two domains, with information exchanged between them on floppy disk. This approach is both time-consuming and potentially risky. This pap...

The Internet today offers primarily a best-effort service. Research and development efforts are currently underway to allow the provision of better than best-effort quality of service assurances. In this article we develop a spot-pricing framework for bandwidth assured Internet service contracts. A nonlinear pricing model forms the basis for the framework. The price process is obtained for diff...

Cloud storage services provide resources for resource-constrained users, which reduces their local overhead and computing cost. As an extension of cloud computing, fog introduces a layer between the users to deploy storage, other types equipment, allowing operate outsourced data conveniently. Although brings many conveniences assured deletion is still one crucial security challenges. This paper...
