manifests as a flexible support for dynamic reconfiguration of
end-to-end communications.
Ravindran further discloses (page 1372, column 1) that the
transport model can be used to support applications requiring
audio-video conferencing on top of current networks that provide
only audio conferencing facilities.
From the disclosure of Ravindran, we agree with the examiner
that Ravindran is silent as to a channel including means for
accepting data for transmission from another channel. However,
we agree with appellants (reply brief, page 3) that CORBA is an
architecture that enables objects to communicate with one another
independent of programming language or operating system, that
CORBA encompasses a great deal of standards and specifications,
and that by using CORBA dynamic API, Ravindran makes clear that
the system is directed to a client-server system using resource
based channels. Thus, we find that Ravindran is not directed to
a publish-subscribe system, but rather to a client-server system,
and does not disclose or suggest that a channel object can
publish to another channel object in a publish-subscribe system.
We additionally find from the disclosure of Ravindran that the
channels are bound to specific media streams, such as a video
stream or an audio stream.
