BrandPost: Edge Computing: Making the Server Room Mission Critical

Spending on Internet of Things (IoT) will reach $1.3 trillion by 2020, and the processing of 43 percent of this data will be at the edge, according to IDC projections. The number of “connected things” will reach 30 billion in 2020 and jump to 80 billion in the following 25 years, the research firm predicts. This market demand is driving the need for new solutions like edge computing.Pendulum Swings Historically, the primary point of IT has swung between the focus on a centralized model and a decentralized one. It started with centralized mainframe computing, then moved to decentralized client-server networks, and then back again to a centralized model in the cloud. Now, the time for the pendulum to swing back to a decentralized model has come in the form of ‘local edge computing.’To read this article in full, please click here

Atmosic and the Power of RF?

I recently talked to a company doing some very interesting things in the mobility space and I thought I’d take a stab at writing about them. Most of my mobility posts are about access points or controller software or me just complaining in general about the state of Wi-Fi 6. But this idea had me a little intrigued. And confused.

Bluetooth Moon Rising

Atmosic is a company that is focusing on low-power chips, especially for IoT applications. Most of their team came from Atheros, which you may recall powers a ton of the reference architectures used in wireless APs in many, many AP manufacturers that don’t make their own chips. Their team has the chops to make good wireless stuff one would think.

Atmosic wants to make IoT devices that use Bluetooth Low Energy (BLE). So far, this is sounding pretty good to me. I’ve seen a lot of crazy awesome ideas for BLE, like location tracking indoors or on-demand digital signage. Sure, there are some tracking issues that go along with that but it’s mostly okay. BLE is what the industry has decided to standardize on for a ton of IoT functionality.

How does Atmosic want to change things Continue reading

IPv6 in Enterprise , Should we still talk about it?

5 years ago Jeff Doyle and I recorded a podcast on IPv6 in Enterprise. We talked about IPv6 addressing plan , adaption and growth rate of IPv6 in Enterprise. In this post I would like to talk about IPv6 deployment status,  challenges and the possible business drivers in IPv6 and I will share my thoughts on …

Private VLANs with VXLAN

Got this remark from a reader after he read the VXLAN and Q-in-Q blog post:

Another area where there is a feature gap with EVPN VXLAN is Private VLANs with VXLAN. They’re not supported on either Nexus or Juniper switches.

I have one word on using private VLANs in 2019: Don’t. They are messy and hard to maintain (not to mention it gets really interesting when you’re combining virtual and physical switches).

Automation: Tools vs Languages

When it comes to expressing intent in automation workflows, there is validation in both using a task or workflow engine and also knocking it together using scripting in some language. I try not to get involved in tool or language wars, but quite honestly sometimes can’t help myself. I’ve even been known to throw fire on the fuel and get the marshmallows out.

Task & Workflow Engines

Sometimes a framework or tool can feel constrained and by design can force you to work in a way that is computable. Let’s take what Ansible or Mistral does. It has a set of ordered tasks, an entry point, some input variables that "flow" through the lists of tasks and some calls to some modules that deal with outputs. I can understand how network engineers don’t like some of these approaches because it feels like dynamic feedback is missing from the engineering. Testing through both verification and validation phases is supposed to replace that immediate dynamic feedback and it can take some time to get used to.

These kinds of automation tools require installation and also the correct modules for integration against the networking components. The tool build can also be automated and Continue reading
