Re: Increase bandwidth usage in partial-mesh network?

[Karsten Thomann via NANOG]

I would agree. Not sure if other vendors have something similar, but in Juniper land you could use traffic engineering with container lsp to go a step further than just plain rsvp-te.

Assuming that the reasons for the low bandwidth and use of radio is due to physical constraints - distances, inhospitable terrain between nodes, etc.  In this case, some good 'ol MPLS traffic engineering using LSP's with bandwidth reservations may be the way to influence how traffic is routed.  Then, they may need some platform to provide observability and potentially dynamic re-routing of LSP's based on actual or predicted congestion situations.  If traffic patterns and utilization are not ideally deterministic, then skip the bandwidth reservation and ensure that the automation is in place to reroute traffic when necessary. I know, adding complexity, but if you just can't build the links you would want, this may be a way to work with what you've got.

I've got a downstream customer asking for help;  they have a private internal network that I've taken to calling the "partial-mesh network from hell": it's got two partially-overlapping radio networks, mixed with islands of isolated fiber connectivity. Dynamic routing protocols (IS-IS, OSPF, EIGRP, etc.) generally will only select the _best_ path, they won't spread the load unless all paths are equal - and they are very unequal in this network, ECMP would likely fail horribly. The network is becoming bandwidth-limited, so they're wanting to make use of all available paths, not just the single "best" path.  It's also remote and spread out, so adding new links or upgrading existing links is difficult and expensive. Oh, and their routers are overdue for a refresh, so acquiring replacement h/w is now possible. Has anyone come across any product or technology that can handle the multi-path-ness and the private-network-ness like a regular router, but also provides the intelligent per-flow path steering based on e.g. latency, like an SD-WAN device (and/or some firewalls)?
