[Fiware-robotics] R: R: Robotics-Kurento call minutes

[Garino Pierangelo]

Hi Luis,

That's already a very helpful feedback, thanks.
We can thus define the kind of VM we'd require.

Hi,
We don't have benchmarks for this, the only rule I can provide you is that the higher the CPU power the higher the number of viewers. In our informal benchmarks we see that with a single CPU it's difficult to have much more than 10 viewers. With 2 CPUs its reasonable to reach 30 or 40.

Best.

Luis.

Hi Pepe and Luis,

Well the number of viewers can be extremely variable: if we organize an small demo e.g. for a meeting, there can be 5-7 viewers. But if we organize e.g. a webinar, then we might have many more viewers (20? 50?).

Luis, is there a direct relationship between the number of viewers and the requirements in terms of processing power? If yes, what could be the 'formula' (or just a rule of thumb) we could use?

Thanks
Pier

Hi,

I suppose that we're going to have several viewers in the live demo. Pier, could we know how many of them? If this data is unknown I'd prefer to assign a large instance to Kurento.

Thank you very much,
Pepe

Hi,
With a tiny you should be able to stream the flow between the robot and the controller. However, if you want to have several viewers or if you want to record the stream, you'll need to use a more powerful machine: the more CPU you add, the higher the scalability you'll reach  ...

Best.

Hi Luis,

We are gathering VM requirements for the live demo. I've found that the StreamOriented blueprint creates a tiny VM, do you think it we'll be enough for us or you recommend different VM size or number of VMs?

Thank you very much,
Pepe

Oggetto: [Fiware-robotics] Robotics-Kurento call minutes

Hi all,
please find a short summary of the Robotics-Kurento call.

Robotics - Kurento call:
*         We should define what are the requirements, e.g. for latency: are we ok with 1/2s latency in our application? Do we need to broadcast the video, or is it used by an operator only?
If we use camera sight as a feedback to move the robot, then 1 or 2 seconds are enough, to operate for that latency I would have to slow down robot ...

     *   For the demo purposes, probably the former is more relevant (we can show to many people the robots moving)
I would set two different profiles:
*         The operator, who needs fast feedback from the camera (less than 0.5s)
*         The viewer(s), who accesses a streaming portal, where above video is usually recasted and codified in different formats
The first is the easiest, but if you try to access it as if you were a viewer (second case) you would have scalability issues, I suppose.


*         Both Kurento blueprints or images can be used on FIWARE Lab

     *   Suggested to use last image available for Kurento in FIWARE LAB
*         Quick instructions:

     *   Open all UDP ports.
     *   Check if Kurento  works in a browser.
     *   If it doesn't work (NAT must allow realtime traffic) it may require to install a  Turn server in FIWARE lab. In this case, ask further instructions to Luis.
*         Different kind of applications available from Kurento repository. The FIWARE Lab image has already several application installed (based on Tomcat on Springboot)  then it should be a better solution than blueprint, which doesn't have any application. Applications are open source, so they could be used to derive the required application for our demo
*         Application server can be on same machine as KMS or not; in the latter case it is required to open port 8888. Ports for Application server are 80, 8080 etc (HTTP).
*         2 Wirecloud widgets available for Kurento: one used for IP camera stream (not useful if using webkit/chrome), the second is for meeting  communication. Perhaps the robot demo could be based on the latter. It is however better to talk to Wirecloud guys about this.

Luis, I also enclose below the link with the slide of the configuration of Robotics GE used in the tests with Kurento (I apologize, I sent the link to many people but I missed your e-mail):
