Workshop goal
The suitability of the object model for the modeling and implementation
of distributed systems has lead to middleware platforms, such as e.g. CORBA,
DCOM, and Java/RMI. Originally, these middleware systems aim at distribution
transparency for application programmers.
However, distributed systems are exposed to system issues, like dynamic
performance changes or partial errors, that prevent a
complete distribution transparency. Quality of Service (QoS) management
addresses these issues. The goal is to add QoS management to the interactions
between clients and services.
Support for QoS management in distributed object systems is a hot topic
of current research which poses a number of open questions: How is QoS
integrated with the object model that emphasizes encapsulation and information
hiding? Can one build generic support frameworks for multiple QoS categories,
in contrast to specialized, single category systems, such as TAO, Electra,
Eternal, DOORS among others. Can QoS be viewed as an aspect in the sense
of Aspect Oriented Programming (AOP) or are other classifications more
appropriate?
This ECOOP-workshop will discuss the open questions and will summarize
the state of the art in the field. The workshop will stimulate discussions
about how next generation QoS management facilities can be built into object
infrastructures. We expect the workshop to attract researchers from several
groups which have working prototypes for this infrastructure. Reports
on prototype systems are welcome as well as theoretical aspects, modeling
techniques, and application scenarios.

Submissions
A one page extended abstract describing your research is required. Selection
of contributions is not only based on the quality of the submitted research
work but also with regard to sessions with a distinct focus. Participants
will have 15 minutes to present their research. Submissions in ASCII, Postscript,
PDF, or HTML are requested by email to qosdos@vsb.informatik.uni-frankfurt.de
The accepted abstracts will be distributed to the other participants.
