[Nfd-dev] NdnCon bridge for NFD calls

[Burke, Jeff]

Dear nfd-dev,

Starting on Tuesday, Peter and Jiachen are going to attempt a bi-directional bridge between the nfd calls on BlueJeans and NdnCon.

If you are interested in trying to participate via NdnCon (I would not rely on this just yet), please follow the informal instructions below first, and then 1) fetch the remap/confbridge stream 2) publish your own stream 3) enter the confbridge chatroom during the call.

Please note that for now, for bidirectional participation (for others to hear you) you'll need to be manually added to the bridge by Jiachen after joining chat.   He or Peter will message you in NdnCon chat after that is done.

Please bear with any weirdness... we're doing these "bridging" tests so that stability / performance issues don't impact the business of the calls.

Thanks,
Jeff

Subject: [Ndn-pis] Your help with ndncon testing

Folks,

We're going to be soon asking for help with testing ndncon (real-time conferencing over NDN for MacOS X) prior to the community meeting. More detailed instructions will come soon, but if you could try the following, it would be much appreciated:

0) Update your OS, if at all possible
1) Install the latest NFD, and start it
2) Download and install ndncon v0.6.3, per the instructions below
3) Start the app and run its auto-update feature (from the Help) menu

Let us know if it appears to be compatible with your system.  Then, if you get this far, and have time:

4) Create a route to the testbed via your closest hub
e.g.,  nfdc register / udp4://spurs.cs.ucla.edu

5) You should see test streams (e.g., "remap", "jb-desktop-test") appear in the left-hand side column of ndncon (perhaps restart if not). Click on the downward facing arrow/triangle at the right to see the various media available for the stream, and click on the arrow associated with a particular media thread, e.g., "camera" or "desktop" to fetch it.  Try different bandwidths if you have time. Feel free to publish too.

Please report any issues or questions to Jiachen Wang <wangjiachen0 at outlook.com>.

We'll have a more detailed request for specific tests coming soon... !

Thanks,
Jeff

Subject: ndncon v0.6.3

Dear all,

I’m pleased to announce that we are ready to share new ndncon version with you and kindly ask you to participate in early adopters tests.

Please, take a look at ndncon test guide here. We’ve setup two test producers so you can try ndncon out. You can find more information in the guide, but in few words, we ask you try this:
- configure ndncon and NFD on your machine
- fetch from one of the test producers for 3-5 minutes and share log files with us (me and Jiachen).

ndncon v0.6.3 can be downloaded from here. During last month, we’ve run numerous tests on our local testbed as well as existing NDN testbed trying to reveal weaknesses in fetching algorithms and improve stability and performance. We feel, that we’re reaching a tipping point in our tests where we can finally start using ndncon for our meetings. Documentation and wiki is still under development, but we’re planning to have it finalized by NDNComm.

I would like to stress out that currently, ndncon provides a paradigm of “video twitter” - i.e. once you start publishing, anyone who can discover you, can fetch your streams. Thus, there is no notion of a “conference”. This task is intentionally left aside for future, because 1/ we were mainly focused on improving NDN-RTC, which was not trivial and 2/ it requires designing a smart signaling protocol for conferences coordination.
Nevertheless, ndncon can and should be used for conferencing. We provided such features as group chats and screen sharing - essential attributes of modern group conferences.

We hope you enjoy playing with ndncon and looking forward for any questions you may have!
Thanks,
