Hi… Knowing that there are locations (or remote locations) with limited internet access, what would be the recommended internet/network bandwidth for 5 concurrent users in order to deploy CDF with a reasonable performance?

Any experience on this matter?

Thanks 

Gustavo

Hello Gustavo,

 

this depends a lot on what you expect these users to be doing. Will they be using CDF platform tools out of the box, doing development or data science work, or work extensively with files, imagery and/or 3D models? For a lot of use cases, the bandwith requirements of CDF are quite limited, but there are certainly also scenarios where high-bandwidth is necessary for a good user experience. If you could tell us a little bit more about the user problems and typical tasks you are expecting them to do, it will be easier to provide some guidance.

 

Best Regards,

Terje.

Hi Terje,

 

Thanks for your reply… At the moment, the case would be basic activities such as data visualization, charts, some basic P&IDs, reports. In the future, maintenance activities might be included. The location is remote with Internet but with limited network/communication infrastructure/capacity.

Thanks in advance,

Gustavo

Thanks Gustavo.

Basic usage of CDF as you describe is not very different from normal internet browsing. We have not tested this extensively (and it varies a lot across our userbase), but I would think that as a ballpark, anything from around 1Mbps should be sufficient (latency will also be a factor, and may slow down some of the interactive elements of the user experience such as cognite charts). I did a quick test, and the Chrome network profile “Fast 3G” worked pretty well, but “Slow 3G” felt very sluggish and provided a poor experience (what is “acceptable” is user-dependent, of course). You can play around with these yourself if you have access to a CDF instance - here is a tutorial explaining this for Google Chrome:

Hi Terje,

Thanks a lot for your reply. This is very helpful in order to have an idea of the initial bandwidth. 

Keep you posted on any additional information.

Cheers

Gustavo
