I have had many people ask me about what Cisco Live is like, from my perspective as a long-time attendee and a member of the Hall of Fame Elite for speakers. While my perspective may be a bit different than your average attendee, I thought I’d give it a shot and write it up.Cisco Live is an amazing event. Some years, I may present at Cisco Live up to 4 times per year, and this was one of those years.
Cancun, Mexico – December 2017
Barcelona, Spain – February 2018
Melbourne, Australia – March 2018
Orlando, Florida, USA – June 2018
When I was a young buck and started attending Cisco Live they were actually called “Networkers” and to me, that still describes the best part of Cisco Live. Not networking in the technology sense, but the human networking that goes on. It’s like a reunion with the people that I get to see year after year; and I get to meet new people every single time.To read this article in full, please click here

When I began my journey in 2015 with SD-WAN, the implementation requirements were different to what they are today. Initially, I deployed pilot sites for internal reachability. This was not a design flaw, but a solution requirement set by the options available to SD-WAN at that time. The initial requirement when designing SD-WAN was to replace multiprotocol label switching (MPLS) and connect the internal resources together.Our projects gained the benefits of SD-WAN deployments. It certainly added value, but there were compelling constraints. In particular we were limited to internal resources and users, yet our architecture consisted of remote partners and mobile workers. The real challenge for SD-WAN vendors is not solely to satisfy internal reachability. The wide area network (WAN) must support a range of different entities that require network access from multiple locations.To read this article in full, please click here

Agility and speed are of paramount importance for most organizations as they try to innovate and differentiate themselves from the competition. The need for flexibility and rapid scalability is driving more and more companies into the cloud, as traditional data centers are no longer proving to be competitive, agile or robust enough.It should come as no surprise that Cisco predicts 94 percent of workloads and compute instances will be processed by cloud data centers by 2021. But deciding when to take the leap, weighing the costs and risks, and developing a successful strategy is easier said than done. Let’s take a closer look at why companies are ditching those data centers and how they can make the transition as smooth as possible.To read this article in full, please click here
As the world has become more cloud- and IoT-centric, the network has increased in value. That is why there has been so much focus on network evolution, particularly in the data center and the wide area network.One part of the network that has lagged in innovation, however, is the network edge. Over the years, the edge of the network has been considered by many to be a commodity. And for many businesses, it is in dire need of a refresh. I’ve talked to some organizations that are running network edge infrastructure that’s approaching 10 years old and haven’t even had a software upgrade in years.[ Related: Getting grounded in intent-based networking ]
The network edge needs to evolve
However, in the words of the esteemed song writer Bob Dylan, “The times, they are a changing” — and so is the role of the network edge.To read this article in full, please click here
Net neutrality officially ended on June 11, 2018, and many people are concerned that this is the end of an open internet. Many supporters of it believe the internet should be regulated no different than the phone system or power utility and that this change will decrease the performance of it. Opponents of net neutrality, argue that the end of it will now increase competition among the various internet service providers (ISPs) and increase coverage, improve performance, and lower costs.What is net neutrality?
Net neutrality became effective by the Federal Communication Commission (FCC) under President Barack Obama in 2015. It is a set of rules that ensured ISPs treated all data transmissions, irrespective to content, that flowed through their infrastructure equally. Net neutrality protections prevented ISPs from slowing web services, blocking access to sites, or charging content organizations for faster delivery of streaming movies or videos. It is believed that antitrust laws did not go far enough in ensuring that all content received equal treatment.To read this article in full, please click here
David Goeckeler doesn’t wear all of the hats at Cisco but he certainly wears one of the biggest.Responsible for 20,000 engineers and $32 billion worth of the networking giant’s business, Goeckeler, executive vice president and general manager, masterminds Cisco's network and security strategy which now features ever more emphasis on software. In fact, at the recent Cisco Live, Goeckeler emphasized that notion saying, “all the routers and switches and wireless access points (and in big networks there are going to be tens of thousands of those in a single enterprise network) we're thinking about that as one large software system.”To read this article in full, please click here
A new global backbone provider emerged from stealth last week, giving organizations even more choice in how they build their Internet-based SD-WANs. Mode introduced what it calls a “software-defined core” (SD-CORE) network that offers IT “affordable private-network reliability and quality of service” across the globe.The company joins Aryaka and Cato Networks as one of the few independent backbone providers helping enterprises solve the variability problems of the Internet core. Middle-mile performance forms the biggest challenge for delivering stable, global, low-latency connections.To read this article in full, please click here
Software and programmable intelligent networks were hot topics at Cisco Live last week, and one of the key components of that discussion was the direction of the company’s SD-WAN strategy.Central to that dialog is how Cisco plans to use and integrate the SD-WAN technology it acquired last year when it bought Viptela for $610 million. For the moment Cisco says Viptela has brought with it interest to the tune of about 800 new customers in recent months.To read this article in full, please click here
Applications have become a key driver of revenue, rather than their previous role as merely a tool to support the business process. What acts as the heart for all applications is the network providing the connection points. Due to the new, critical importance of the application layer, IT professionals are looking for ways to improve the architecture of their network.A new era of campus network design is required, one that enforces policy-based automation from the edge of the network to public and private clouds using an intent-based paradigm.

The race to automate
An autonomous network was once seen as part of a utopian ideal, albeit one far off into the future. It would make up the backbone of everything we did, managing a hyper-connected world in which everything from the minutiae of knowing when the milk in the fridge needed replacing, to the ability of the network to automatically ramp services up or down, without the need for human intervention.In a recent ACG Research survey of network service providers, internet content providers, cloud service providers and large enterprises, 100 percent of respondents said they felt the need to pursue automation, and 100 percent are optimistic about automation’s future. Additionally, 75 percent of respondents indicated that they’ll have full or significant network automation within the next five years.To read this article in full, please click here
In campus networking, there are a number of emerging trends impacting the way networks will be modeled in the future. These arising trends include mobility, Internet of Things (IoT), and uniformed security across the wired and wireless connections.To be in tune with these trends, a new era of networking is required that enforces policy-based automation from the edge of the network to public and private clouds using an intent-based paradigm. An example of such would be SD-Access.To read this article in full, please click here
Cisco’s annual user event, Cisco Live, is being held in Orlando, Florida, this week. While Orlando is home to DisneyWorld, Universal Studios and other places where fantasies come true, the one thing that isn’t make-believe is the turnaround of Cisco since Chuck Robbins took over as CEO. When the baton was passed to Robbins in August of 2015, Cisco’s stock was trading at about $25/share and had been moving sideways for years. Today, it’s trading at about $45/share and at a 17-year high, and the turnaround is well underway.Cisco goes back to the network
How did Robbins get Cisco’s mojo’s back in such a short period of time? The answer lies in its roots and a refocus on the network. In fact, when Robbins took over as CEO, I wrote a post outlining some priorities for him as he stepped into the role. My first point was to approach IT through the lens of the network. In the years leading up to the transition to Robbins, I felt Cisco had tried too hard to prove itself as a server and traditional IT vendor instead of staying true to networking.To read this article in full, please click here

When it comes to computing, living on the edge is currently all the rage. Why? Edge computing is a way to decentralize computing power and move processing closer to the end points where users and devices access the internet and data is generated. This allows for better control of the user experience and for data to be processed faster at the edge of the network – on devices such as smartphones and IoT devices.As enterprise organizations look to extend their corporate digital channel strategies involving websites with rich media and personalized content, it is vital to have a strong resiliency strategy.Deploying a combination of cloud and edge services can help by: reducing unplanned downtime; improving security and performance; extending the benefits of multi-cloud infrastructure; speeding application development and delivery; and improving user experience.To read this article in full, please click here
2018 is shaping up to be a banner year for all things Ethernet.First of all, the ubiquitous networking technology is having a banner year already in the data center where in the first quarter alone, the switching market recorded its strongest year-over-year revenue growth in over five years, and 100G Ethernet port shipments more than doubled year-over-year, according to a report by Dell’Oro Group researchers.[ Now see who's developing quantum computers.]
The 16-percent switching growth was, "driven by the large-tier cloud hyperscalers such as Amazon, Google, Microsoft and Facebook but also by enterprise customers,” said Sameh Boujelbene, senior director at Dell’Oro.To read this article in full, please click here
Since the advent of the internet and IP, networking technology has not seen a seismic shift of this magnitude that is occurring in Enterprise networks today. As organizations move from on-premises application hosting to a cloud-based approach, they are inundated with the inherent challenges of legacy network solutions. The conventional network architectures in most of today’s enterprises, were not built to handle the workloads of a cloud-first organization. Moreover, the increasing usage of broadband to connect to multi-cloud-based applications have escalated concerns around application performance, agility, and network security.Software-defined WAN (SD-WAN) has gained immense traction among CIOs lately. Gartner forecasts that SD-WAN will grow at a 59% compound annual growth rate through 2021 to become a $1.3 billion market. This is because there are a myriad of payoffs of moving to SD-WAN: Primarily, SD-WAN enables easier access to cloud and SaaS based applications for geographically distributed branch offices and mobile work force. Here are but just a few other important benefits that SD-WAN brings to digital-first organizations:To read this article in full, please click here

Traditional location positioning such as GPS isn’t going to be suitable for a Location of Things world filled with Internet of Things (IoT) sensors, say experts. The centralized, anchor-like system we use now, as found in GPS, mobile network cell tower positioning services, and Wi-Fi-based location positioning, is going to be a problem. The usual suspects being bandwidth, excessive power use, and cost.The problem is IoT devices are required to communicate with positioning anchors, whether it be satellites or radio towers. That’s bandwidth-intensive; it can use a significant amount of power to cover the distances, as well as to power the multiple chips needed. The system is also conceivably susceptible to congestion as the numbers of devices increases — projections are for billions and billions of IoT things worldwide, ultimately.To read this article in full, please click here
