– To bring QoS to the Internet, several better-than-best-effort network services have been recently devised with significant efforts. The goal of this paper is to measure the effective performances of existing applications after incorporating QoS, and to understand what are the effects of provisioning QoS in the applications. Our experiments use two kinds(More)
The Distributed Resource Controller (DRC) technology described in this paper provides a novel approach to interfacing applications with emerging network mechanisms to deliver Quality of Service (QoS) and controlling network resource utilization. DRC aims to unify network services (e.g., Diffserv, Intserv, and ATM) and application QoS provisioning by(More)
Distributed multimedia applications are sensitive to the Quality of Service (QoS) delivered by underlying communication networks. The main question this work addresses is how to adapt multimedia applications to the QoS delivered by the network and vice versa. We introduce QoSockets, an extension to the sockets mechanism to enable QoS reservation and(More)
This paper describes novel market-based technologies that uniquely establish quantifiable and adjustable limits on the power of attackers, enable verifiable accountability for malicious attacks, and admit systematic and uniform monitoring and detection of attacks. These technologies, incorporated in the MarketNet system, establish a financial economy to(More)
This paper describes novel market-based technologies for systematic, quantifiable and predictable protection of information systems against attacks. These technologies, incorporated in the MarketNet system, use currency to control access to information systems resources and to account for their use. Clients wishing to access a resource must pay in currency(More)
