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 introducing a middleware system and a set of generic interfaces. DRC middleware is the core part that translates application requests for QoS delivery into respective access to underlying network systems in a manner that optimizes resource utilization and shelters applications from such a complexity. Applications can request QoS to the DRC middleware in two ways: either in-line using the DRC QoS API or off-line via the DRC utility. Application QoS requirements are specified in terms of two categories of parameters: Traffic Profile (quantitative) and User Expectation (qualitative). DRC currently uses the CORBA-based object-oriented technology to develop a CORB A-based Resource Controller (CRC). The working CRC prototype built to manage the Integrated Services is also presented.

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. The MarketNet project has developed novel information systems protection mechanisms based on market-based paradigms. These mechanisms seek to ensure the systematic, quantifiable, and predictable survivability of large-scale information systems. Specifically, MarketNet has pursued the following objectives: a) Control access to protected resources and domains and establish quantifiable and tunable limits on the power of attackers to access or damage critical information systems resources; b) Establish full accountability among separately administered and mutually distrustful domains, and enable rapid tracing and isolation of attack sources; c) Provide resource-independent instrumentation to monitor resource access, detect intrusion attacks automatically, identify their sources, rapidly isolate attack sources, and deny access, and d) Provide quantifiable protection against loss of critical resources due to attacks or failures. The project has successfully accomplished the design and development of substantial new technologies for protecting systems and applications, including the software implementation of the core MarketNet mechanisms and protection of several network services. NUMBER OF PAGES AbstractThe MarketNet project has developed novel information systems protection mechanisms based on marketbased paradigms. These mechanisms seek to ensure the systematic, quantifiable, and predictable survivability of large-scale information systems. Specifically, MarketNet has pursued the following objectives: (A) Quantify and control access to protected resources and domains. (B) Establish tunable limits on the power of attackers to access or damage critical information systems resources. (C) Establish full accountability among separately administered and mutually distrustful domains, and enable rapid tracing and isolation of attack sources. (D) Provide resource-independent instrumentation to monitor resource access, detect intrusion attacks automatically, identify their sources, rapidly isolate attack sources, and deny access. (E) Provide quantifiable protection against loss of critical resources due to attacks or failures.The project has successfully accomplished the design and development of substantial new technologies for protecting systems and applications, including the software implementation of the core MarketNet mechanisms and protection of several network services. Specifically:• The MarketNet system, the first market-based protection system;• The MarketNet-based protection of network services such as SNMP and the Java Virtual Machine; • Mechanisms for quantification and tuning of exposure to attacks;• Market-based mechanisms for intrusion and undesirable access detection; and• Application of Market-based mechanisms for the pro...
