Two ACSs

[Simon Ryf]

Hi all,

I don’t understand the use of splitting different cwmp-events to different instances, probably because it has not yet been explained why by Pera *wink* ;-).

However, I have had thoughts about load balancing and redundancy with GenieACS. As this thread is somewhat related here my question to Zaid / Dan:

Do you see any issues having two (separate / with different IP’s) instances of cwmp, nbi & gui accessing the same mongoDB of GenieACS?
I assume that since there is no CPE accessing both instances of cwmp at the same time, there is not going to be a write conflict within MongoDB – am I right?

We use dockerized GenieACS (one container as GUI and another as CWMP/NBI/FS) for some time now quite successfully. Being able to scale that up having multiple instances of a container maybe even on different Bare-metals would be nice but I don’t make the effort of testing if you say that this could cause write conflicts on the mongoDB.

As a side note: I also thought of separating CWMP, NBI and FS going more in the direction of micro-services – however getting also reduced container sizes would mean to deal with npm and knowing what service is using what library. And I have yet to come across another language making such a painfully overcomplicated and complete mess regarding libs as node/js. (Sorry I had to say that). If someone did that already – please let me know :)

Simon

Without having looked at any proxy, I’m saying off the top of my head it would take a custom proxy/code to make this work.

So you think that the thing is in the proxy? I was thinking of using HAproxy for this and setting it to foreword messages containing "4 VALUE CHANGE" to ACS1 and the others to ACS2 but i don't know if that would do the trick...

You would need a proxy with some custom code to make this work. You could write a proxy in your language of choice. But out of the box this is not possible.

I agree that it is complex but I need to know if it is possible and if you have any suggestions on how to do it. As far as I have seen in TR069 document I wpuld need some kind of a proxy in front of the ACSs as modem can have only one ACS...

Why? That sounds like needless complexity.

Yes that's right. I want to do a refresh of the device (updating parameters) with one ACS and a reboot with the other.

Not sure I understand your question. It's the incoming HTTP requests
from your CPEs that you want to distribute to your two ACS nodes.
