The Distributed Object Computing (DOC) Group is a distributed research
consortium lead by Dr. Douglas
C. Schmidt and consisting of the DOC group in ISIS at Vanderbilt University, Nashville
and the Center
for Distributed Object Computing in the Computer Science and Engineering
department at Washington
University. The DOC Group also includes members at Remedy IT, Riverace Corporation, PrismTech, and Object Computing Inc. The purpose
of the DOC group is to support advanced R&D
middleware, and modeling tools using an open
source software development model, which allows academics,
developers, and end-users to participate in leading-edge R&D
projects driven by the free market of ideas, requirements, and
The most popular and widely used open-source middleware platforms and
modeling tools developed by DOC group focus on distributed real-time
and embedded (DRE) systems and include:
You can download all the source-code, documentation, regression tests,
and example applications for most of these middleware platforms and
tools here. You can
download a list of the projects we're currently working on here.
- ACE, which
provides a rich set of reusable C++ wrapper facades and framework
components that perform common communication software tasks across a
range of OS platforms.
which is CORBA middleware that allows clients to invoke operations
on distributed objects without concern for object location,
programming language, OS platform, communication protocols and
interconnects, and hardware.
which is a real-time CORBA Component Model (CCM) implementation built on top of
which is the Deployment And Configuration Engine built on top of
CIAO that implements the OMG Deployment and
- ZEN, which is an
implementation of Real-time CORBA implemented using Real-time Java.
which is a collection of domain-specific modeling languages
and their associated analysis/synthesis tools developed using the Generic Modeling
Environment (GME) to support various
phases of DRE system development, assembly, deployment,
configuration, and quality assurance.
- CUTS, which is a
system execution modeling (SEM) tool designed using the Generic Modeling
Environment (GME) to conduct system integration tests
continuously throughout the software lifecycle to identify
performance problems before they become to harder to locate and
- JAWS, which
is a high-performance HTTP web server.
which is the Resource Allocation and Control Engine built
on top of CIAO that allocates resource (such as memory, computational power, network bandwidth, etc,)
and manages application QoS and system resource utilization in
various operating conditions by performing necessary control actions.
- Skoll, which
is a Distributed Continuous Quality Assurance environment.
- GEMS, which
is a configurable toolkit for creating domain-specific modeling
and program synthesis environments for Eclipse.
- OpenDDS, which
is an open-source implementation of the Object Management Group
Distribution Service (DDS). OpenDDS leverages ACE to
provide a cross-platform environment, with C++ and Java bindings.
- DDS Benchmark, which investigates the performance of pub/sub data distribution service
