This paper describes the MarketNet architecture for survivability of large-scale information systems. In MarketNet, access to information system resources is governed by a market economy. Processes purchase services from resource managers using their budgets and seek to optimize the Quality of Services (QoS) they obtain, while resource managers seek to(More)
– 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)
1. ABSTRACT This paper describes novel market-based technologies for systematic, quantifiable and predictable protection of information systems against attacks. MarketNet establishes a financial market to regulate and protect access resource access and to account for their use. A domain offers access to its resources to cIients who can pay with its(More)
