we're pretty similar in that we've made UISP a mess.  Multiple paths to a pop.  multiple pops on the network.  failover between pops.  Lots of 'other' devices. handing out /29 etc to customers.

Some sort of discovery would be nice.  Ideally though, pulling something from SNMP or router APIs etc to build the paths, but having a 'network elements' list with each of the links described.  ie, backhaul 12 has MACs ..01 and ...02 at 300x100 and then build the topology around that from discovery.  

I've also thought about doing routine trace routes or watching TTLs or something like that to get some indication that topology has changed and then do another discovery and potential tree rebuild.

This is awesome! Way to go here. Thank you for contributing this.
Being able to map out these complex integrations will help ISPs a ton, and I really like that it is sharing common features between the Splynx and UISP integrations.

Thanks,
Robert

So I've been doing some work on getting UISP integration (and integrations in general) to work a bit more smoothly.

I started by implementing a graph structure that mirrors both the networks and sites system. It's not done yet, but the basics are coming together nicely. You can see my progress so far at: https://github.com/thebracket/LibreQoS/tree/integration-common-graph

Our UISP instance is a great testcase for torturing the system. I even found a case of UISP somehow auto-generating a circular portion of the tree. We have:
  • Non Ubiquiti devices as "other devices"
  • Sections that need shaping by subnet (e.g. "all of 192.168.1.0/24 shared 100 mbit")
  • Bridge mode devices using Option 82 to always allocate the same IP, with a "service IP" entry
  • Various bits of infrastructure mapped
  • Sites that go to client sites, which go to other client sites
In other words, over the years we've unleashed a bit of a monster. Cleaning it up is a useful talk, but I wanted the integration to be able to handle pathological cases like us!

So I fed our network into the current graph generator, and used graphviz to spit out a directed graph:

That doesn't include client sites! Legend:

  • Green = the root site.
  • Red = a site
  • Blue = an access point
  • Magenta = a client site that has children
So the part in "common" is designed heavily to reduce repetition. When it's done, you should be able to feed in sites, APs, clients, devices, etc. in a pretty flexible manner. Given how much code is shared between the UISP and Splynx integration code, I'm pretty sure both will be cut to a tiny fraction of the total code. :-)

I can't post the full tree, it's full of client names.
