Hi, 

Somehow I have a feeling that these latency requirements are related to all projects, this is why they should be documented in the Deployment options section.

Gerg0,
I think these 3 projects are implied from the wiki requirements.
But it will be good to state projects that may need work explicitly.
Thanks,
Arkady

Hi, 

Should we add these to the Deployment Scenarions section of the Dublin wiki [1]?

It is more than just nova to keystone.
We also need to consider at least neutron, glance and cinder also.

Yes, 5ms is one way. But this is an assumption based on the network from China Mobile. The latency will be defer if you have different distance, but the calculation method is the same apparently.

Should we separate two kinds of latency requirements:
	- Federation Latency: i.e Central Keystone to Local Keystone 
	- API latency: i.e.  Edge Nova to local Keystone

Should we measure it one way or Round Trip? I assume the 5ms below is one way.

    Thank you Adrien. I was just about the reply with more details.
    
    About latency, this as I understand is actually decided mostly by the distance of the distributed cloud. So it actually decided by where exactly the location Keystone would like to deploy, and what is the distance expectation. Like what I explain in my presentation, we plan to have keystone sitting in the city level to control multi cloud in counties, and the latency will be around 5ms. But again this is a certain situation for China Mobile. And other operators may make the conlusion on a different structure. Another thing we can do is work on simulation and testing and see what kind of latency the current keystone federation scheme can tolerant. This will help the operators to work out there structure as well. 
    
    About bandwidth, the impression for me is we could expect more than 50GB of bandwidth for edge for 5G. And I think that is enough for most of the app.
    
    Hope this will help.

    It is rather difficult to give numbers because there are several use-cases. 
    However, a good starting point can be to give a look to the presentation Qiao Fu gave during the Vancouver summit: https://www.openstack.org/videos/vancouver-2018/edge-tic-future-edge-cloud-for-china-mobile
    There is a lot of numbers regarding the infrastructure China Mobile is envisioning. 
    
    Hope this helps.

    PS: I cannot attend the meeting  yesterday unfortunately but I'm wondering whether the disconnection aspects have been discussed (i.e. the fact that one site can be completely isolated for a certain period of time  due to network disconnections).
