Tutorial

36 Pattern-Oriented Software Architecture: Patterns for Concurrent and Networked Objects

Monday, 27 October – 8:30-17:00 Full day

Douglas Schmidt, Vanderbilt University, d.schmidt@darpa.mil

Developing concurrent and networked object-oriented applications is hard; developing high-quality reusable components for these types of applications is even harder. The principles, methods, and skills required to develop reusable software cannot be learned by generalities. This tutorial, therefore, illustrates by example how to significantly simplify and enhance the development of communication software that effectively utilizes concurrency and distribution via the use of:

  • Object-oriented design techniques, such as patterns, layered modularity, and data/control abstraction
  • Object-oriented language features, such as abstract classes, inheritance, dynamic binding, and parameterized types
  • Middleware, such as object-oriented frameworks for host infrastructure middleware (e.g., ACE) and component middleware (like J2EE, the CORBA Component Model, and .NET)
  • Advanced operating system mechanisms, such as event demultiplexing, multi-threading, multi-processing, and explicit dynamic linking

The tutorial examines patterns and framework solutions abstracted from production systems in domains including from telecommunications, avionics, online trading systems, medical systems, web servers, and real-time object request brokers to illustrate the key technical design and implementation issues. The material presented in this tutorial is based on the book "Pattern-Oriented Software Architecture: Patterns for Concurrent and Networked Objects," Wiley & Sons, 2000.

Attendee background

Prerequisites: Participants must be familiar with object-oriented development techniques (such as patterns, modularity, and information hiding), OO language features (such as classes, inheritance, dynamic binding, and parameterized types), systems programming concepts (such as process/thread management, synchronization, and IPC), and networking terminology (such as client/server architectures and TCP/IP).

Presenter

Dr. Douglas C. Schmidt is a Professor in the Electrical Engineering and Computer Science department at Vanderbilt University. His research focuses on patterns, optimization techniques, and empirical analyses of object-oriented frameworks that facilitate the development of distributed real-time and embedded (DRE) middleware. Dr. Schmidt has over fifteen years of experience developing DRE middleware as the chief architect and developer of ACE and TAO, which are widely used, open-source middleware containing a rich set of components that implement patterns for DRE systems. Dr. Schmidt has also served as a Deputy Director and a Program Manager at DARPA, where he led the national R&D effort on DRE middleware.
