<p class=MsoPlainText>From: Andras Kovacs <akov@niif.hu><o:p></o:p></p>
<p class=MsoPlainText>Reply-To: akov@niif.hu<o:p></o:p></p>
<p class=MsoPlainText>Organization: NIIF/HUNGARNET<o:p></o:p></p>
<p class=MsoPlainText>To: svctest@listserv.niif.hu<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Hi All,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>First of all, I would like to thank to Vidyo for their
commitment in<o:p></o:p></p>
<p class=MsoPlainText>such testings. Hopefully, we will be able to do an
extensive testing in<o:p></o:p></p>
<p class=MsoPlainText>the forthcoming weeks and that will be a valuable input
for you as well.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>These are the first technical questions to Vidyo
(discussed in Bruges<o:p></o:p></p>
<p class=MsoPlainText>with some GN2 people).<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>1. Firewall/NAT traversal:<o:p></o:p></p>
<p class=MsoPlainText> o What is the current technology you promote?<o:p></o:p></p>
<p class=MsoPlainText> o We heard about Vidyo proxy, what is it all about?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Notes (with researcher community hat on):<o:p></o:p></p>
<p class=MsoPlainText> o We have been experiencing that H.323/SIP does not
fly due to<o:p></o:p></p>
<p class=MsoPlainText>firewall/NAT traversal problems (often requires days of
fw/NAT debugging)<o:p></o:p></p>
<p class=MsoPlainText> o Adobe and other webconferencing solutions use HTTP
tunneling<o:p></o:p></p>
<p class=MsoPlainText> o We think that an HTTP tunneling option would solve
any of the problems<o:p></o:p></p>
<p class=MsoPlainText> o We also think that Vidyo proxy solution (as far as
we understand it)<o:p></o:p></p>
<p class=MsoPlainText>is not feasible, since a European-level service would
require deployment<o:p></o:p></p>
<p class=MsoPlainText>thousands of gateways, which is obviously impossible.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>2. Audio stream delivery:<o:p></o:p></p>
<p class=MsoPlainText> o We are wondering how audio delivery is happening in
your solution.<o:p></o:p></p>
<p class=MsoPlainText> o Since Vidyo router is switching packet, we suppose
that audio mixing<o:p></o:p></p>
<p class=MsoPlainText>is also avoided.<o:p></o:p></p>
<p class=MsoPlainText> o How the audio delivered without mixing? All-to-all?
What happens<o:p></o:p></p>
<p class=MsoPlainText>when 20 participants are there?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>3. AAI enabling the web interface:<o:p></o:p></p>
<p class=MsoPlainText> o What do you think, is there a chance to AAI-enable
(maybe Shibboleth<o:p></o:p></p>
<p class=MsoPlainText>or eduGAIN) your Vidyo portal?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>4. Camera support:<o:p></o:p></p>
<p class=MsoPlainText> o We have just received some information on this issue<o:p></o:p></p>
<p class=MsoPlainText> o A few notes:<o:p></o:p></p>
<p class=MsoPlainText> - Is there a plan to support firewire cameras (many
of our users use<o:p></o:p></p>
<p class=MsoPlainText>e.g. a Sony camera on a tripod to get better quality and
autofocus)<o:p></o:p></p>
<p class=MsoPlainText> - I understand you being USB-biased due to better
performance by the<o:p></o:p></p>
<p class=MsoPlainText>OS/drivers. It is still a question whether a huge
userbase (generally<o:p></o:p></p>
<p class=MsoPlainText>thinking) could tolerate this or not? (ie. forcing all
users to get rid<o:p></o:p></p>
<p class=MsoPlainText>of good old PCI hardware).<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>5. Dialling out/inthrough gateway:<o:p></o:p></p>
<p class=MsoPlainText> o Currently, we use e.164 for both H.323 and SIP<o:p></o:p></p>
<p class=MsoPlainText> o How the dialling in (to Vidyo cloud) is done at the
gateway? (How a<o:p></o:p></p>
<p class=MsoPlainText>user could indicate Vidyo meeting room?)<o:p></o:p></p>
<p class=MsoPlainText> o How the dialling out is done? (How the number
translation is done to<o:p></o:p></p>
<p class=MsoPlainText>E.164 at the gateway?)<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>6. Management of Vidyo solution:<o:p></o:p></p>
<p class=MsoPlainText> o How is the management done of Vidyo components
(portal, router,<o:p></o:p></p>
<p class=MsoPlainText>gateway, etc.)?<o:p></o:p></p>
<p class=MsoPlainText> o How to configure them?<o:p></o:p></p>
<p class=MsoPlainText> o Is there SNMP support for standard based regular
retrieval of system<o:p></o:p></p>
<p class=MsoPlainText>parameters?<o:p></o:p></p>
<p class=MsoPlainText> o How conferences/users could be monitored?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>7. Gateway:<o:p></o:p></p>
<p class=MsoPlainText> o It would be very important to test the gateway
solution due to<o:p></o:p></p>
<p class=MsoPlainText>interoperability issues (protocol and codec compatibility).<o:p></o:p></p>
<p class=MsoPlainText> o Can you please provide general technical information
about the gw?<o:p></o:p></p>
<p class=MsoPlainText> o What is the capacity of the gateway (number of calls
in function of<o:p></o:p></p>
<p class=MsoPlainText>transcoding done)<o:p></o:p></p>
<p class=MsoPlainText> o How a layout is assembled at the gateway
(transmitting a VC from<o:p></o:p></p>
<p class=MsoPlainText>Vidyo cloud to H.323/SIP world)? Are all the Vidyo
participants decoded,<o:p></o:p></p>
<p class=MsoPlainText> assembled onto a screen, and encoded? Is there voice
activated modes<o:p></o:p></p>
<p class=MsoPlainText>where louder speakers are on the screens?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Sorry for the question-tsunami. ;)<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thanks in advance.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Cheers,<o:p></o:p></p>
