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.

Amazon S3 Outage: We’ve All Been There

I’ve been thinking a little bit about the Amazon S3 incident. Not really the incident, actually, but the responses to it. More than once I read something along the lines of “I’m sure that guy got fired” with regard to the engineer who entered the fatal command.

Sure, that’s kind of funny for a quick tweet or in the greater context of a blog post on change control, but for me, I’m not sitting at my desk shaking my head right now. Instead, I’m reminded about the times I did the exact same thing (on a much smaller scale) and will probably do it again.


How Do You Know That’s True?

About a thousand years ago, rather than configure routers, I taught high school English.

One day, instead of unpacking our favorite Shakespearean sonnet, I was sidetracked by a student who asked me how we know anything about electrons and how they orbit the nucleus of an atom. Apparently he asked his physics teacher the period before and got a pithy “electrons are the essence of a negativity.”


Trust But Verify: Lossless End-To-End Visibility from Ixia

Tap everywhere. Tap everything. Trustworthy visibility is the key to network monitoring and security.

This is Ixia’s approach for how networking professionals can get an accurate picture of what’s really going in the network, and this was the theme of Ixia’s presentation at Networking Field Day 13.


Intent-Driven Networking with Apstra at Networking Field Day 13

In a couple weeks I’ll be headed to sunny San Jose for Networking Field Day 13. If you’re not familiar with Networking Field Day and other Field Day events, check out their website, YouTube channel, Twitter feed, and LinkedIn page. Tech Field Day does a great job bringing technology influencers, bloggers, and craft beer enthusiasts together with some of the biggest and newest names in the tech industry.

I’m particularly interested in Apstra’s presentation on Thursday afternoon. I recently wrote an article about intent-driven networking, something of particular interest to me, so I’m really interested to hear what they have to say about their platform, the Apstra Operating System, or AOS.


Your wired LAN is dumb…or at least it should be

Why aren’t our wired LANs more like WLANs? Wireless vendors have already been doing for years what switch manufacturers are only starting to get into in the last couple years. A rough comparison of a few attributes of typical wired and wireless networks shows striking differences in how we manage our LANs and WLANs.
