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. - Riley On Sunday, September 14th, 2025 at 2:29 PM, Mike Hammett via NANOG <nanog@lists.nanog.org> wrote:
I have a radio station customer who is utilizing one of those streaming services to bring their broadcast station online. We've received a complaint of a half dozen or so 1-second drops in connectivity over the Internet to this streaming service in the six or so months they've been a customer. I consider that pretty amazing service delivery. However, the customer does not. I suspect this is a layer 8 issue, but what have your experiences been in these kinds of situations, and what technical remedies would be available? I don't know what sub-second failover systems exist, but I'm sure they're not cost-effective if they do.
