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.
