Ethernet Turns 40 — and Continues To Influence the Technology Landscape

“The farther back you can look, the farther forward you are likely to see.”

 – Winston Churchill

It is nearly impossible – even foolish – to look ahead without looking back. Glimpses into the past can give us inspiration for new innovations and even teach us what not to do. Behind every great technological innovation is a solid legacy product or solution that inspired it or played an integral part in its development. Behind the printing press was paper and block printing. Behind the telephone was the telegraph. And behind the Internet of Everything (IoE)? Ethernet.Ethernet Turns 40

Today – May 22 – marks the 40th anniversary of Ethernet. In 1973, technologist and 3Com founder Robert Metcalfe designed the Ethernet to allow computer devices to communicate with each other using radio-like signals over an antenna cable. Long used for reliable and efficient access to information, its implications on the networking world reach far past the local area network (LAN).

Over the course of 40 years, our quest for connecting the unconnected continues. Our connections have become increasingly complex since Metcalfe was tasked with connecting several Xerox computers to a single printer, and we need to understand the possibilities in both the number and value of our modern-day connections.

In a previous blog post, How the Internet of Everything Will Change the World…for the Better, I referenced Metcalfe’s law: the power of the network is greater than the sum of its parts. True. But the parts need to be recognized and optimized in order to maximize this power. The Internet of Everything is a large-scale metaphor for Metcalfe’s law. The combined connections of people, processes, data, and things don’t just amount to a list of things that are connected. The actionable insights that exist with the power of networked connectivity exponentially create the Internet of Everything.

Ethernet has helped further the progress that these connections – and the insights gleaned from them – will have on the Internet of Everything. So, today we celebrate not only the introduction of Ethernet, but also the technologies it made possible.

Securing the Internet of Everything: An Introduction

Towards developing a Secure Architecture for the Internet of Everything, I plan to kick off a series of blogs around this pivotal topic.

In discussing security and the Internet of Everything, the first question that comes to mind is, “Which segment of “everything” is one referring to?”. A reasonable approach has been to understand the common attributes that crosses vertical segments such as Intelligent Transportation, Smart Utilities, Industrial Automation and so on. The Internet of Things (IoT) and Machine-to-Machine (M2M) are general abstractions for the network infrastructure that links physical and virtual objects. In Cisco, we now refer to these abstractions as the Internet of Everything, IoE. The IoE describes a world where billions of objects have sensors to detect, measure and assess their status; all connected over public or private networks using standard and proprietary protocols.

Until a point in time around 2008/2009, there were more human beings in the world than devices connected to the Internet. That is no longer the case.  Read More »

Making Connections When Mother Nature Hits

May 15, 2013 at 11:45 am PST

When natural disasters strike, our first instincts are to phone or text loved ones; check news and social media sites; and go online to lend support. These connections become our lifelines. In the process, mobile devices become paramount in connecting people to people and people to data.

That’s why the Internet of Everything (IoE) is so critical. In the moments immediately following a disaster popular social media networks, like Facebook and Twitter, serve as quick ways to locate loved ones. At the same time, social media allows those affected to inform multiple people at once that they are okay, with a simple tweet or post.

In a recent Forbes article titled “Everything Changes with the Internet of Everything,” Kevin Maney discusses how the Internet of Everything changes the way we respond in time of crisis. For example, the Google Person Finder (launched during the 2010 earthquake in Haiti) shows how the Internet can make a big difference during emergencies. People can access the site via mobile device or computer and enter into one of two portals to exchange information: “I’m looking for someone” or “I have information about someone.”

Similarly, a networked power grid can pinpoint outages, enabling faster trouble shooting and allowing fellow citizens to lend support (or even power strips, as seen during Superstorm Sandy) where needed. These connections bring communities back together.

We often talk about the power of IoE to connect the unconnected. For disaster recovery, that power is amplified. Through the Internet of Everything we can help expedite recovery and create a more efficient disaster-response effort by connecting processes, data, things and, most importantly, people. When that happens, we’re able to improve the human experience.

What Einstein’s Theory of Relativity and the Internet of Things have in common

Cisco published earlier this week the 2013 Cisco Global IT Impact Survey, exploring the relationship between IT and the business goals of the companies they support.  Among other things, 42 percent of those interviewed responded that they know about the Internet of Things, “as well as I know Einstein’s Theory of Relativity.” In other words, beyond a passing knowledge of e=mc2, the relevance of the Internet of Things to IT is about as illuminated as a black hole.

Does that really matter at this point? you might ask.  Isn’t the Internet of Things about Nike FuelBands and talking toasters?  In fact, a lot of what we call “industrial automation” or “safety and security” is the leading edge of the Internet of Things.  It’s already here today, called into the service of greater efficiency, productivity, and safety.  This is “operational technology” instead of “information technology”:  in other words, technology that directly monitors or controls physical objects and processes, such as assembly lines on a factory floor.

This has enormous implications for IT:

1. Security threats go from the merely cyber to the cyber-physical. Gartner summed it up nicely in the WSJ last week.  And let’s not even talk about Shodan

2. Beyond BYOD.  The consumerization of personal electronic devices transformed the enterprise networking landscape.  IT adapted to the new security threats posed, figured out how to associate multiple devices to a single user, etc.  Now imagine “bring your own programmable logic controller.”

3. Redefining networking scalability and data management.  And we thought video was a huge driver of traffic on the network.  SAP and Harris Interactive recently estimated that 4 billion terabytes of data will be generated this year alone. (For some idea of the scale, take a single IoT use case — smart meters.  Jack Danahy estimated 400MB of data per year.  Not much, you say? Multiply that by, say, 1 million households, and you get 400 terabytes already. For a single use case. In one city.)

IT has much to offer, and should.  As proprietary connectivity networks converge onto TCP/IP, IT can bring its expertise in securing IP-based networks. With experience in deploying cloud services, IT can bring in network management best practices.  And with expertise in software-defined networking, IT can help re-architect networks to support immense scale, real-time requirements, analytics at the edge, and more.

From the outside-in, the Internet of Things may seem like a fast-moving train that’s zooming by too fast to board. But if you’re in IT, get on board: you’ll experience relativity and relevance.

Birth of a New Class of Data in the Internet of Everything

May 8, 2013 at 1:56 pm PST

Data generated by people and data generated by machines is actually quite different and as we move from the Internet of Things

Cisco_data-in-motion[1][2]

to the Internet of Everything, this has some pretty interesting implications.

Data generated by things or machines is actually quite structured: A sensor is programmed or created to produce only a specific type of d

ata. Count the cars that cross the intersection, for example.  And it’s predictable, sending a signal at specified intervals which makes the data pegged to a specific moment in time, as is the data’s relevance.  It’s also generally low bandwidth, as you would imagine:  A single signal from a sensor, providing specific data on a short time horizon.

Data generated by people, on the other hand, is highly unpredictable – I don’t know who I’m going to call or email and whether there’s a photo op when I step outside.  Data from humans is unstructured, from spreadsheets to blooper videos, and has historical relevance. Tax returns, photos of your kids, the novel in draft in your desk drawer.  It’s moderate to high bandwidth, depending on what you’re doing and it’s always on, always available. Read More »
