VVI Announces Availability Of Vving

State College, PA USA, 26 November 2001: VVI today announced the
availability of Vving for Mac OS X version 10.1. John Brilhart, Chief
Technical Officer of VVI, makes this statement:

"Vving is a well designed and precise application that measures and graphs
network performance in real time. It provides an immediate solution with no
learning curve, something everyone appreciates. It also demonstrates the
high scalability of our OpenGraph programming framework. For example, Vving
can display millions of points in realtime and show data ranging from
seconds to years. Although Vving shows just a small portion of the
OpenGraph features I think it is a good application to demonstrate
OpenGraph. Starting today we are providing complimentary copies of Vving by
order via the Internet for that purpose."

John adds: "Vving is based on our OpenGraph framework. We've been working
on a redesign of OpenGraph for two years now. OpenGraph was already one of
the most advanced programming frameworks I am aware of. However, we wanted
to make OpenGraph ten times better than before. In order to accomplish that
we specified a proprietary programming language and wrote a compiler and
software project management system for that language and the design of
OpenGraph. Then we converted over half a million lines of OpenGraph code by
hand to that system and also added code. In the conversion we incorporated
many new design concepts that are a result of over ten years of experience
and product development in object-oriented technology. The new OpenGraph
meets all our expectations and provides a basis for addition of many new
and major code enhancements that we will produce in future versions."
