Pattern-Oriented Software Architecture: Patterns for Concurrent and Networked Objects
Convention Ctr — Room 15
Douglas Schmidt, University of California, Irvine

Developing software for distributed systems that effectively utilizes concurrency over high-speed, low-speed, and mobile networks is a complex task. This tutorial describes how to apply patterns and frameworks to alleviate the complexity of developing concurrent and distributed communication software. These patterns and framework components have been used successfully by the speaker on production communication software projects at hundreds of commercial companies for telecommunication systems, network management for personal communication systems, Web-based content delivery systems, electronic medical imaging systems, real-time aerospace systems, distributed interactive simulations, and automated stock trading. The tutorial illustrates by example how to significantly simplify and enhance the development of communication software that effectively utilizes concurrency and distribution via the use of:
  • OO design techniques – such as patterns, layered modularity, and data/control abstraction
  • OO language features – such as abstract classes, inheritance, dynamic binding, and parameterized types
  • Middleware – such as object-oriented frameworks for infrastructure middleware (such as ACE) and distribution middleware (such as CORBA ORBs)

The material presented in this tutorial is based on the book, Pattern-Oriented Software Architecture: Patterns for Concurrent and Distributed Objects (Wiley 2000), which is the second volume in the highly acclaimed Pattern-Oriented Software Architecture (POSA) series.

Attendee Background: The tutorial is intended for software developers who are familiar with general object-oriented design and programming techniques (such as patterns, modularity, and information hiding) fundamental OO programming language features (such as classes, inheritance, dynamic binding, and parameterized types), basic systems programming concepts (such as process/thread management, synchronization, and interprocess communication), and networking terminology (such as client/server architectures and TCP/IP).

Presenter: Dr. Schmidt is an Associate Professor in the Electrical and Computer Engineering Department at the University of California, Irvine. He is currently also serving as a program manager the DARPA Information Technology Office (ITO) where he is leading the national research effort on distributed object computing middleware. His research focuses on design patterns, implementation, and experimental analysis of object-oriented techniques that facilitate the development of high-performance, real-time distributed object computing middleware on parallel processing platforms running over high-speed networks and embedded system interconnects. Dr. Schmidt is an internationally recognized and widely cited expert on distributed object computing patterns, middleware frameworks, and Real-time CORBA, and has published widely in top IEEE, ACM, IFIP, and USENIX technical journals, conferences, and books. His publications cover a range of experimental systems topics including high-performance communication software systems, parallel processing for high-speed networking protocols, real-time distributed object computing with CORBA, and object-oriented design patterns for concurrent and distributed systems.
