TELoIP at Networking Field Day 15

No Networking Field Day would be complete without a presentation from an SD-WAN vendor. The technology is now established and maturing into a ubiquitous WAN solution across small and large enterprises alike, so at the upcoming Networking Field Day 15, I’ll be focused on how TELoIP, one of the presenters at the event, differentiates itself from its competitors.

TELoIP is a little different from most other SD-WAN vendors in that it offers a managed WAN solution and has its own cloud infrastructure into which customers connect. This isn’t a common approach among SD-WAN vendors, but it also isn’t exclusive to TELoIP. That’s why I’m really interested in knowing how they differ specifically from vendors using a similar approach but also how they’re better than the broader scope of SD-WAN providers.

I’m not going to explain what SD-WAN is other that to say that it’s basically an overlay on top of your WAN to allow for intelligent path selection based on link quality and other traffic engineering such as per packet flow aggregation. This is powerful technology that’s been running in production environments for several years at least at this point.

That means that my questions aren’t really about how SD-WAN works or what their secret sauce does to make the magic happen. Instead, I want to know how TELoIP treats SD-WAN as a separate function from WAN optimization and how that plays into security concerns.

It also means that I want to learn about their service delivery and how TELoIP works with providers of their solution to deliver the last mile between the TELoIP PoPs and the customer edge.

The SD-WAN component isn’t groundbreaking anymore. To me, the technology lost it’s sheen already. That doesn’t mean I’m not interested in SD-WAN or don’t recognize the benefits of the technology, it just means that I’m more interested now in service delivery and operational aspects.

I still have some technical questions in mind, but I’m looking forward to learning how TELoIP is positioning itself and why. Check out their website and their presentation at Networking Field Day 15 by tuning into Tech Field Day’s YouTube channel. Also make sure to follow the discussion on Twitter using #NFD15.

SD-WAN with VeloCloud at Networking Field Day 13

It looks like we’re going to have some SD-WAN goodness next week at Networking Field Day 13. I love the technology itself because of the real-world use case and practical benefits a good SD-WAN solution can offer.  Many of the SDN-labeled offerings out there are still a little immature, but adding intelligence to the WAN edge is something that is already being adopted wholeheartedly in even small enterprises.

SD-WAN with Silver Peak: The Business Use Case

Amidst discussion of SDN ambiguity at Networking Field Day 11, SD-WAN stood apart as something we understood, and I think that’s because we understood its use case very well.
