Re: Resilient Internet

[Riley O via NANOG <nanog () lists nanog org>]

I've heard about this being an issue in broadcast journalism. The mobility of news vans adds another layer to this. 
From what I've heard, broadcasters are a big part of the SD-WAN market.

Packet duplication and dedup is common in SD-WAN implementations. Another user mentioned parallel feeds, and this would 
be one way to achieve that.

I imagine you'd need some kind of frame replication or PRP/HSR to do this without the SD-WAN overlay. It could be kind 
of involved. Maybe there's a way it can be done with broadcast/multicast traffic on the traditional networking side.  


One last thought, it could be worth a check to see if drop times align with changes in your RIB/FIB. You may have an 
flappy, but more preferred route to the service provider.

With all given odds, the cause likely sits outside of your subscriber/AS boundaries anyway. At 1 second it might as 
well be solar flares or EMF interference from the station itself.
