Q&A With Santa Cruz Networks
There are so many ways of looking at VoIP and that
must have been what got Santa Cruz Networks (news)
(not to be confused with Santa Cruz Operation (news)
of the Linux lawsuit fame) into the market. On the face of it all, they
have a simple application, a platform for sharing voice, video, data and
documents with presence built in. What begins to differentiate the service
is the ability to have 200 people on an IP call using a single system
(keep reading, it can scale even further). This is an impressive number.
The product name that allows this capability is the
Real-Time Communications Exchange (RTCX). At the moment, all clients on
this product are restricted to Windows. RTCX has lots of features, some of
which are graphically pleasing such as the ability to drag the video
screen around your monitor (the GUI is object based).
What really makes RTCX interesting to me is that it
doesn�t use UDP to transmit packets, it uses TCP while taking advantage of
SSL. They further use multiple sessions to send packets -- sort of like
spread spectrum in the wireless field. Audio is sent multiple times over
multiple sessions. You can have an effective communications session in as
little as 20 Kbps and the system checks the network every 30 milliseconds
and adjusts accordingly. Another advantage of TCP is that it passes easily
through firewalls and doesn�t require punching holes in existing ones or
the purchase of new firewalls.
I did get a chance to demo the service briefly on a
congested network and was surprised at how good the quality was� Both
video and audio. I now have a demo account and it is my hope to write
about my experiences soon in an article or my
BLOG.
The product is available to service providers as well
as resellers and enterprises. The company is further interested in making
their RTXP or real-time exchange protocol into an open standard, so it
could eventually interoperate with SIP for example.
The cost for an enterprise of 2,000 users is $85,000,
while service providers pay $100,000 for that many users. You can buy the
solution as software, hardware or a
service. The company impressed upon me that peer-to-peer products are
great until you want to scale. At 20,000 users at a time (Nine Call
Extension Units (CXUs) make this happen), we are talking serious scale
here.
