GRE Tunnels – Generic Routing Encapsulation – Use Cases

GRE Tunnels  GRE tunnels are by far most common tunnelling technology. Very easy to setup, troubleshoot and operate. But in large scale deployment, configuring GRE tunnels become cumbersome, because GRE tunnel is a point to point tunnel.   GRE Tunnel Characteristics    • GRE tunnels are manual point to point tunnels. Tunnel end points are not automatically […]

5 Enterprise WiFi Pitfalls to Avoid

Net Neutrality (Again and Again and Again)

Net neutrality is one of those topics that should never have existed, but of course it inevitably erupts every so often, so here we go…

Not so long ago Robert Graham published his anti-net-neutrality arguments which are (no surprise) not much different from what I wrote when I still cared about this argument (here, here, here and here). While I agree with his overall perspective, I completely disagree with his view of Comcast’s initial response to network congestion.

Worth Reading: Encryption substitutes

Policy experts have suggested that the rise of encrypted data is not the end of intelligence collection because law enforcement can look to substitutes other sources of intelligence, such as metadata that prove to be just as valuable or more valuable than decrypting encrypted data. This paper focuses on the other side of that insight: on the substitutes available for privacy-seekers beyond encryption, such as placing one’s data in a jurisdiction that is beyond the reach of law enforcement. This framework puts encryption in context: there are many ways to keep one’s data private, just as there are many ways that the government might get access to that data. While encryption is typically treated as a stand-alone computer security issue, it is a piece of a larger debate about government access to personal data. —Andrew Keane Woods @ Scirbd

IDG Contributor Network: SunPower technology powers solar plants using Krypton Cloud

The installed capacity of solar power in the U.S. now exceeds all other forms of power generation.Generating solar power at scale with thousands of panels requires new approaches to monitoring and management. Since 2004, SunPower has designed, constructed, managed and supplied high performance solar power plants around the world. More than 3 gigawatts of solar plants rely on SunPower technology today. How does SunPower monitor thousands of solar panels across hundreds of power plants? How are performance issues remotely diagnosed and troubleshot in real-time? How are false alerts distinguished from real ones? To read this article in full or to leave a comment, please click here

An OS for Neuromorphic Computing on Von Neumann Devices

Ziyang Xu from Peking University in Beijing sees several similarities between the human brain and Von Neumann computing devices.

While he believes there is value in neuromorphic, or brain-inspired, chips, with the right operating system, standard processors can mimic some of the efficiencies of the brain and achieve similar performance for certain tasks.

In short, even though our brains do not have the same high-speed, high-frequency capacity of modern chips, the way information is routed and addressed is the key. At the core of this efficiency is a concept similar to a policy engine governing information compression, storage, and retrieval. …

An OS for Neuromorphic Computing on Von Neumann Devices was written by Nicole Hemsoth at The Next Platform.

On the ‘web: Getting Involved with the IETF

I sat with Greg, Kathleen, and Alia to talk about “ordinary engineers” getting involved in the IETF while we were in Prague. Believe it or not, this time I didn’t get out into the city at all other than walking between the hotel I was staying at and the venue hotel. I try to always take “one day off” and do something around the city we are in, but the schedule didn’t allow it this time. Anyway, here is the link—

Greg Ferro attended the IETF 99 meeting in Prauge in July 2017. In this Priority Queue show, he sits down with Kathleen Moriarty, an IETF Security Area Director; Alia Atlas, a Routing Area Director; and Russ White, a co-chair of a variety of working groups and all-around community leader; to discuss opportunities for IT professionals to get directly involved with the IETF in networking, security, and other areas. —Packet Pushers

IDG Contributor Network: The ultra-optimistic case for AI in business

You’ve seen the headlines: Artificial intelligence is a job killer. It will end humanity. At the very least, it will lead to social unrest.The truth is, no one really knows what changes AI will bring. What’s indisputable is that it’s already here and it’s getting more prevalent by the day. IDC predicts that worldwide revenues from cognitive and AI systems will grow 59.3% this year to $12.5 billion and will achieve a compound growth rate of 54.4% through 2020, when revenues will hit $46 billion.To read this article in full or to leave a comment, please click here

The Next Scalability Hurdle: Massively Multiplayer Mobile AR

Many moons ago, in Building Super Scalable Systems: Blade Runner Meets Autonomic Computing In The Ambient Cloud, I said we still had scaling challenges ahead, that we've not yet begun to scale, that we still don't know how to scale at a planetary level.

That was 7 years ago. Now Facebook has 2 billion monthly users. There's no reason to think they can't scale an unimpressive 3.5x to handle the rest of the planet. WhatsApp is at one billion daily users. YouTube is at 1.5 billion monthly users.

So it appears we do know how to service a whole planet full of people (and bots). At least a select few companies with vast resources know how. We are still no closer to your average developer being able to field a planet scale service. The winner take all nature of the Internet seems to fend off decentralization like it's a plague. Maybe efforts like Filecoin will change the tide. 

There's another area we have scaling challenges: Massively Multiplayer Mobile AR (Augmented Reality). While AR has threatened to be the future for quite some time, it now looks like the future may be just around the virtual Continue reading

Worth Reading: The economics of port breakout

Port-breakout deployments have become a popular networking tool and are driving the large industry demand for parallel optics transceivers. Today, port breakout is commonly used to operate 40/100Gbps (40/100G) parallel optics transceivers as four 10/25Gbps (10/25G) links. Breaking out parallel ports is beneficial for multiple applications, such as building large scale spine-and-leaf networks and enabling today’s high-density 10/25G networks. The latter task is the focus of this article. —Jennifer Cline And David Hessong @ the Data Center Journal

The 10 most powerful companies in enterprise networking

There is no shortage of vendors competing for business at every part of the enterprise network - every vertical, every size business, from the edge to the core. None are created equal, but a few have separated themselves from the pack to become the 10 most powerful.This is Network World's understanding of the most powerful enterprise networking companies, which we based on our own research, consultations with trusted industry analysts and the work of our in-house journalists. For our purposes, we thought of power mostly as market share in key areas of the enterprise networking marketplace - specifically core networking, monitoring and management, WLAN and the edge, though we did consider their technology bases and important market factors as well.
