Overview
--------

In the past few years, several component-oriented programming (COP)
middleware technologies, such as CORBA/CCM, COM/COM+, JavaBeans/EJB,
and .NET, have emerged as a way to reduce software development cost
and time-to-market in a broad range of domains. The COP paradigm
defines capabilities that support a runtime environment where software
components can be installed and assembled into applications
declaratively.  Much like an operating system defines systemic
capabilities and services (such as file I/O, synchronization, and
process management) of a computation environment for application
programs, the COP middleware virtual software operating environment
defines the systemic capabilities and services (such as remote method
invocation, transactional and persistent state behaviors) of the
virtual environment for components to use to perform their designated
functionality using higher level abstractions.

Most existing COP middleware, however, focuses on specific application
domains, such as GUI programs or enterprise applications. As a result,
they mainly provide abstractions of services that are required for
these application domains. It is therefore hard to apply existing COP
middleware to other application domains that require different sets of
systemic services since many of these services cross-cut multiple
layers and mechanisms in COPs. For example, an increasing number of
applications (such as multimedia streaming services, mobile
applications, and distributed real-time embedded (DRE) applications)
require stringent quality-of-service (QoS) to function
properly. Implementing these service aspects into component
implementations are either impossible or yield a set of tightly
coupled components that are hard to reuse individually.

A distributed computing system can provide a wide range of QoS
including timeliness, fault-tolerance, scalability, latency,
throughput, and security. Different application domains require
different QoS requirements and have different constraints.  To
maximize the scope of COP middleware applicability, it is useful to
compose QoS provisioning and supporting mechanisms into COP frameworks
in the same fashion applications are composed in COP frameworks. This
approach facilitates the use of COP middleware to different
application domains with different QoS requirements.

This workshop aims to bring together researchers and practitioners to
explore new ideas and exchange experiences in enhancing COP frameworks
to support composable QoS.  The goal is to review the state-of-the-art
in the research of composable QoS, and the what, why, and how of
supporting and specifying composable QoS in COP.

Submission Guidelines
---------------------

Participants are expected to submit a position paper of up to 5 pages
in PDF, Postscript, or MS Word format to workshop organizer at
<nanbor at cs.wustl.edu>.  Papers submissions will be reviewed by the
program committee.  All accepted workshop papers will be available at
the workshop website prior to the workshop date to give all
participants the opportunity to read them before the workshop and to
encourage discussion during the workshop.

Topics of interest to this workshop include, but not limit to the
following:

  * What QoS aspects need to be separated

  * Composition standards for QoS composition

  * Mechanisms to support various QoS properties

  * Interface standards to control various QoS properties

  * How to represent QoS requirements in COP metadata?

  * How to compose QoS provisioning and mechanisms

  * Open research issues with composable QoS behaviors

  * Application scenarios for components in distributed embedded
    systems, such as mobile phones and PDAs

  * Relating architectural principles/approaches to composable QoS
    behaviors

  * Architecture description languages for specifying QoS mechanism
    supports

  * Ways of inserting adaptive behaviors

  * Performance/efficiency of COP systems

  * Experiences in implementing COP applications with stringent QoS
    requirements

  * Domain-specific requirements

  * Integrating components from multiple vendors

  * Reconciliation and interoperability among various COP standards

  * Performance/efficiency of COP systems

  * Heavyweight versus lightweight component models

  * Methodologies and tools for provisioning QoS resources in COP
    applications.
