This paper introduces a new packet marking algorithm that can be used in the context of Assured Forwarding (AF) in the Differentiated Services (DiffServ) framework [1], [2]. The new marking algorithm is called Equation-Based Marking (EBM) and is based on the TCP model in [3]. EBM is to handle the problems found in other marking schemes regarding fairness among heterogeneous TCP flows through a ...

Providing secure and efficient access to large scale outsourced data is an important issue of cloud computing. In this paper, a mechanism FADE, a secure overlay cloud storage system, which will guarantee assured file deletion and improved access control for outsourced data is proposed. Cryptographic approach is used for storing and managing data..

This paper describes an application of the TrustCoM environment to support secure contract based collaboration between companies using managed web services. The application scenario describes a consortium of engineering companies that seek to upgrade a customer’s fleet of aircraft to provide in-flight internet capabilities. The environment supports the consortium to collaborate so as to take ad...

As Internet is rapidly growing and receiving traffic from multimedia applications that are sensitive to available bandwidth and delay experienced in the network, there is a strong need for quality of service (QoS) support. The Integrated and Differentiated Service models are two approaches for adding QoS to Internet. The Assured Service is an end-to-end service based on the Differentiated Servi...

Evolving and refactoring concurrent Java software can be error-prone, resulting in race conditions and other concurrency difficulties. We suggest that there are two principal causes: Concurrency design intent is often not explicit in code and, additionally, consistency of intent and code cannot easily be established through either testing or inspection. We explore several aspects of this issue ...

Standard protocols for sampling and measuring odor emissions from livestock buildings are needed to guide scientists, consultants, regulators, and policy-makers. A federally funded, multistate project has conducted field studies in six states to measure emissions of odor, coarse particulate matter (PM(10)), total suspended particulates, hydrogen sulfide, ammonia, and carbon dioxide from swine a...

In this paper we propose an edge-based quality of service architecture aimed at site-to-site private networks over the Internet. We extend the traditional point-to-point service model to a point-to-set service model, assuming a finite, bounded set of destination sites. A point-to-set service allows a user to have a pool of premium tokens, which could be flexibly assigned to traffic going toward...
