QualProbes: Middleware QoS Profiling Services for Configuring Adaptive Applications [chapter]

Baochun Li, Klara Nahrstedt
2000 Lecture Notes in Computer Science  
In this paper, we present QualProbes, a set of middleware QoS Probing and Profiling services to discover such relationships at run-time.  ...  It is widely accepted that in order to deliver the best Qualityof-Service (QoS), applications need to be adaptive to the fluctuating computing and communication environments.  ...  A detailed analysis of QualProbes services is presented, including the application model, the dependency tree model for application QoS parameters, and the QoS profiling algorithm implemented in the QualProbes  ...

Design, implementation, and performance of an automatic configuration service for distributed component systems

Fabio Kon, Jeferson Roberto Marques, Tomonori Yamane, Roy H. Campbell, M. Dennis Mickunas
2005 Software, Practice & Experience  
This article presents the results of our six-year research (from 1998 to 2003) in the area of automatic configuration, describing an integrated architecture for managing dependencies in distributed componentbased  ...  The problem behind all these difficulties is the lack of a unified model for representing dependencies and mechanisms for dealing with these dependencies.  ...  Herbert Yutaka Watanabe was responsible for the J2EE implementation of the Automatic Configuration Service.  ...

Complementary methods for QoS adaptation in component-based multi-agent systems

J. Zinky, R. Shapiro, S. Siracuse
IEEE First Symposium onMulti-Agent Security and Survivability, 2004  
In the hostile computing environments typical of large, distributed, multi-agent systems, dynamic adaptation to changes in quality of service (QoS) is essential to the survival of the system.  ...  These complementary methods can be configured to match any given fielded environment, trading off the overhead of each adaptation against its benefit.  ...  Qualprobes: Middleware QoS Profiling Services for Configuring Adaptive Applications, Proceedings of the IFIP/ACM Conference on Distributed Systems Platforms and Open Distributed Processing (Middleware  ...
