Open Implementation Toolkit for Building Survivable Applications
Found in: DARPA Information Survivability Conference and Exposition,
By Partha P. Pal, Joseph P. Loyall, Richard E. Schantz, John A. Zinky, Franklin Webber
Issue Date:January 2000
pp. 1197
We consider two aspects of survivability, namely survival by adaptation and survival by protection. We show how the Quality Objects (QuO) distributed adaptive middleware framework enables us to introduce these aspects of survivability in a flexible and sys...
 
Building Auto-Adaptive Distributed Applications: The QuO-APOD Experience
Found in: Distributed Computing Systems Workshops, International Conference on
By Michael Atighetchi, Partha P. Pal, Christopher C. Jones, Paul Rubel, Richard E. Schantz, Joseph P. Loyall, John A. Zinky
Issue Date:May 2003
pp. 104
Exploiting autonomic adaptation in defending a distributed application is a relatively new research area. We describe how the QuO adaptive middleware was used to implement auto-adaptive defenses ranging from simple rapid-response sensor-actuator tactics to...
 
Defense-Enabled Applications
Found in: DARPA Information Survivability Conference and Exposition,
By Franklin Webber, Partha P. Pal, Richard E. Schantz, Joseph P. Loyall
Issue Date:June 2001
pp. 1119
Abstract: Some applications can be given increased resistance to malicious attack even though the environment in which they run is untrustworthy. We call any such application
 
Next-Generation Mobile Computing
Found in: IEEE Software
By James Edmondson,William Anderson,Jeff Gray,Joseph P. Loyall,Klaus Schmid,Jules White
Issue Date:March 2014
pp. 44-47
This issue of IEEE Software discusses where the mobile computing has brought us today and where it could be taking us in the future. It provides a glimpse into the near future of mobile computing by focusing on proximate software challenges coupled with pr...
   
Dynamic Quality of Service Management for Multicast Tactical Communications
Found in: Object-Oriented Real-Time Distributed Computing, IEEE International Symposium on
By Matthew Gillen, Joseph P. Loyall, Joshua Sterling
Issue Date:March 2011
pp. 11-18
Wireless networking is moving toward the adoption of IP protocols and away from the multitude of special-purpose tactical radios traditionally in the hands of emergency personnel, military personnel, and law enforcement. The adoption of standards, such as ...
 
Dynamic Policy-Driven Quality of Service in Service-Oriented Systems
Found in: Object-Oriented Real-Time Distributed Computing, IEEE International Symposium on
By Joseph P. Loyall, Matthew Gillen, Aaron Paulos, James Edmondson, Pooja Varshneya, Douglas C. Schmidt, Larry Bunch, Marco Carvalho, Andrew Martignoni III
Issue Date:May 2010
pp. 1-9
Service-oriented architecture (SOA) middleware has emerged as a powerful and popular distributed computing paradigm due to its high-level abstractions for composing systems and hiding platform-level details. Control of some details hidden by SOA middleware...
 
Integrated Adaptive QoS Management in Middleware: A Case Study
Found in: Real-Time and Embedded Technology and Applications Symposium, IEEE
By Christopher D. Gill, Joseph P. Loyall, Richard E. Schantz, Michael Atighetchi, Jeanna M. Gossett, David Corman, Douglas C. Schmidt
Issue Date:May 2004
pp. 276
Distributed real-time and embedded (DRE) systems in which application requirements and environmental conditions may not be known a priori-or which may vary at run-time-can benefit from an adaptive approach to management of quality-of-service (QoS) to meet ...
 
Timeliness in Auto-Adaptive Distributed Systems
Found in: Distributed Computing Systems Workshops, International Conference on
By Partha Pal, Richard E. Schantz, Joseph P. Loyall
Issue Date:March 2004
pp. 354-359
Designers of auto-adaptive systems must devise a way to engage the right response at the right time. In order to bring auto-adaptive capabilities to mainstream distributed systems, it must be ascertained that the adaptation architecture is capable of mount...
 
Application of the QuO Quality-of-Service Framework to a Distributed Video Application
Found in: Distributed Objects and Applications, International Symposium on
By David A. Karr, Craig Rodrigues, Joseph P. Loyall, Richard E. Schantz, Yamuna Krishnamurthy, Irfan Pyarali, Douglas C. Schmidt
Issue Date:September 2001
pp. 0299
Abstract: Adaptation of distributed software to maintain the best possible application performance in the face of changes in available resources is an increasingly important and complex problem. We discuss the application of the QuO adaptive middleware fra...
 
Specification and implementation of Actors with graph rewriting
Found in: Proceedings of the workshop on Object-based concurrent programming (OOPSLA/ECOOP '90)
By Joseph P. Loyall, Simon M. Kaplan, Steven K. Goering
Issue Date:October 1990
pp. 89-99
The paper presents a discussion and a specification of an exception handling system dedicated to object-oriented programming. We show how a full object-oriented representation of exceptions and of protocols to handle them, using meta-classes, makes the sys...
