It’s reasonable to think that it’s segment routed in some way, the advantages there are numerous and pretty clear. It would give them the significant advantage of being able to leverage a PCE controller architecture and provide a lot of LFA options for resiliency. My money would be there, either SR-MPLS or SRv6. Not a lot of options for SRv6 at this time (some ur not many). It’s not outside the realm of possibilities by any stretch of the imagination. nb On Wed, Jun 30, 2021 at 6:35 PM Michael Richardson wrote: > > Dave Taht wrote: > > going village to village on the same sat would save a ton of backhaul > > bandwidth and offer less latency for things like phone calls.
