Living Live: Decentralized IP and SDI Routing


On this episode of Living Live with Ross Video, host Tyler Kern was joined by Ross Video Marketing Product Manager, Connectivity & Control Todd Riggs to discuss the ins and outs of decentralized IP and SDI routing.

While these aren’t new topics, a focus on IP transport topologies and a move to UHD and 4K productions have spurred a new look.

“Both of these things are stressing some equipment that we’ve had, traditionally, so we’re having to work around some of those issues within the equipment,” Riggs said. “But there’s also some promise with some of this that’s allowing us to explore different workflows.”

In the past, the way to build a large-scale router involved leveraging combiners, tie lines and more that could facilitate those bigger infrastructures.

As technological advancements were made, these large-scale routers shrunk down to a single chassis. However, even these infrastructures didn’t have the bandwidth required for today’s applications.

Now, with decentralized IP, unprecedented distributed models are able to be scaled to sizes that weren’t possible in the past.
However, there is no one-size-fits-all solution, even for a frontier this promising.

“In fact, I would probably say that, for the majority of customers, a decentralized model probably doesn’t make sense,” Riggs said. “(That’s) simply because I don’t know people that have unlimited budgets, and cost is a factor. These models tend to be a bit more expensive up front just because of the way you build these out.”

Still, these decentralized models are helping shift workflows by providing scalability and ways to link multiple sites together in a much more efficient manner than single-frame models.
