A case for Predictive DiffServ on mobile networks
Found in: A World of Wireless, Mobile and Multimedia Networks, International Symposium on
By Nadia Shalaby, John Zinky
Issue Date:June 2008
pp. 1-7
Differentiated Service is intended to achieve scalable service differentiation within the network. A protocol with its QoS semantics left up to off-line service level agreements (SLAs) between the network and application, it is inapplicable to mobile envir...
QoS Issues for Wide-Area CORBA-Based Object Systems
Found in: Object-Oriented Real-Time Dependable Systems, IEEE International Workshop on
By David E. Bakken, Richard E. Schantz, John A. Zinky
Issue Date:February 1996
pp. 110
CORBA is a distributed object technology which shows great promise in simplifying the task of programming applications which must operate over a wide area network (WAN). However, WAN environments are dynamic and hostile, making applications which are distr...
Transparent Insertion of Custom Logic in HTTP(S) Streams Using PbProxy
Found in: IEEE Internet Computing
By Michael Atighetchi, Brett Benyo, Abhimanyu Gosain, Robert MacIntyre, Partha Pal, Virginia Travers, John Zinky
Issue Date:May 2011
pp. 43-50
<p>Cost and testing considerations limit the acceptance and deployment of technologies that make information exchanges more secure, reliable, semantically understandable, and self-improving. PbProxy is a flexible proxy that enables transparent insert...
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...
Comparing and Contrasting Adaptive Middleware Support in Wide-Area and Embedded Distributed Object Applications
Found in: Distributed Computing Systems, International Conference on
By Joseph Loyall, Richard Schantz, John Zinky, Partha Pal, Richard Shapiro, Craig Rodrigues, Michael Atighetchi, David Karr, Jeanna M. Gossett, Christopher D. Gill
Issue Date:April 2001
pp. 0625
Abstract: The Quality Objects (QuO) middleware is a set of extensions to standard distributed object computing middleware that is used to control and adapt quality of service in a number of distributed application environments, from wide-area to embedded d...
Using QDL to Specify QoS Aware Distributed (QuO) Application Configuration
Found in: Object-Oriented Real-Time Distributed Computing, IEEE International Symposium on
By Partha Pal, Joseph Loyall, Richard Schantz, John Zinky, Rich Shapiro, James Megquier
Issue Date:March 2000
pp. 310
Recent work in opening up distributed object systems to make them suitable for applications needing quality of service control has had the side effect of increasing the complexity in setting up, configuring, and initializing such applications. Configuratio...
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...
PASS - A service for Efficient Large Scale Dissemination of Time Varying Data Using CORBA
Found in: Distributed Computing Systems, International Conference on
By John Zinky, Dave Bakken, Vijaykumar Krishnaswamy, Mustaque Ahamad
Issue Date:June 1999
pp. 0496
A common class of wide-area distributed applications remotely collect time varying data and send it to consumers around the network.Some examples of these include network management, stock ticker data, and event logs.The environment in which these applicat...
An Object-level Gateway Supporting Integrated-Property Quality of Service
Found in: Object-Oriented Real-Time Distributed Computing, IEEE International Symposium on
By Richard Schantz, John Zinky, David Karr, David Bakken, James Megquier, Joseph Loyall
Issue Date:May 1999
pp. 223
As networks and the use of communication within applications continue to grow and find more uses, so too does the demand for more control and manageability of various
The Effects of Infrequent But Difficult Inputs Conditions on N-Version Programming
Found in: EUROMICRO Conference
By John Zinky, Joshua Etkin
Issue Date:September 1997
pp. 510
The software reliability of a system based on N-version programming is dominated by how well infrequent but difficult inputs conditions are handled. In traditional single version programming, these inputs are responsible for only a small percentage of soft...
Visualizing packet traces
Found in: Conference proceedings on Communications architectures & protocols (SIGCOMM '92)
By Fredric M. White, John A. Zinky
Issue Date:August 1992
pp. 406-415
This paper describes an environment for visualizing packet traces that greatly simplifies troubleshooting protocol implementations. Network management centers routinely collect packet traces to tally traffic statistics and to troubleshoot protocol configur...
