Parenting in a hyper-connected world is increasingly challenged by lack of visibility into children’s internet usage, and by limited controls to customize internet usage policies per child. About a year ago, I installed a home router with parental-controls. My kids (teenage girls!) quickly complained about the additional latency it introduced on the network. User experience was clearly in the tank. I soon discovered that those controls were not granular enough to customize for different times of the day, for different users, and down to individual devices.
By then, I realized that I had to fundamentally rethink my home network in order to become a more effective parent. I needed better insight into my network’s traffic. Finally, last fall, the geek in me awakened and I deployed a full-fledged Cisco network in my home with advanced Application Visibility & Control (AVC) capabilities, providing me deep insight into my home’s internet traffic.

An Unforgettable Experience
It’s 6 a.m. on a Saturday. Filled with excitement and anticipation, I watched as my hot air balloon, the last one in the bunch, inflated. Around me, one after another, balloons started to float effortlessly off the ground into the air. The Napa Valley’s sun glittered in the distant as my balloon finally took off. At 1,050 feet, some fogs rolled by, then I saw it: a shadow of my balloon in the fog encircled by a rainbow – see the picture above, top right. I quickly pulled out my iPhone 6, snapped a panoramic, and posted it on Facebook. It was the most mesmerizing experience ever, not just because of the experience itself, but also because I can share it with my families and friends via 4G LTE. However, 4G LTE isn’t just for smartphones.
Connecting the Unconnected
The world of things, a.k.a Internet of Things (#IoT), around us is connecting in ways beyond imagination. According to a November 2014 issue of the Harvard Business Review, “Smart, connected products are changing how value is created…(and) will affect the trajectory of the overall economy, giving rise to the next era of IT-driven productivity growth for companies, their customers, and the global economy.” For example, just-in-time inventory replenishment, powered by connected vending machines, enables one business to capitalize on OpEx savings and increase revenue per unit. Wireless monitoring allows an oil and gas company to quickly respond to pipeline issues in rugged, remote locations. Connected lightning empowers one smart city to reduce crime rate and improve its residents’ quality of life. Even one’s personal space, such as the home, is becoming more connected with the use of #WEMO products and smart devices integration (those coming to #CES, you must see the Connected Home demo). This Digital Transformation, powered by 4G LTE, brings about considerable improvements in the ways we work, live, and play. Read More »

Two weeks ago, a leading global medical device manufacturer came to Cisco for advice. In an effort to streamline IT operations and reduce operating costs, the customer had recently migrated from their internal Microsoft Exchange 2010 environment to Office365, Microsoft’s hosted online service.
The migration was initially done for the headquarter users and the feedback was more positive than they expected. However, when they migrated their branch and remote office users, the WAN bandwidth usage almost immediately spiked and user experience suffered as a result.
This customer is certainly not the only company looking to embrace Cloud applications for greater agility, reduced costs and complexity, and increased productivity. Or has had to deal with BYOD issues and the increasing impact of video has on their bandwidth. However, what our customer and those other companies have found is that the current method of backhauling the traffic to the data center is no longer a viable way to handle the increased consumption when faced with a flat or even a declining IT budget. Therefore, many of today’s distributed enterprises are looking to use direct Internet access pathways in an effort to improve the user experience while reducing IT costs.
However, enabling direct Internet access (DIA) at branch offices also forfeits the inherent threat protection that traffic routed through the data center provides. The enterprise-level risks that branch offices face with BYOD issues, compliance requirements, and advanced persistent threats require enterprise-level security. According to Gartner’s “Bring Branch Office Network Security Up to the Enterprise Standard”, “By 2016, 30% of advanced targeted threats — up from less than 5% today — will specifically target branch offices as an entry point.”
Cisco FirePOWER Threat Defense for ISR addresses these issues by extending their industry-leading FirePOWER threat protection beyond its traditional network edge and data center deployments out to individual Cisco ISR routers. Read More »

The WAN: Then and Now
The Wide Area Network (WAN) has been at the foundation of enterprise networks for decades: responsible for connecting people, applications and data across a large number of locations. Traditionally, the WAN was relatively static and a “set it and forget it” configuration methodology was acceptable and effective. Management tools were simple and straightforward, yet limited. As an example, while studying for my Routing and Switching CCIE lab exam 15 years ago, I had to become proficient in command line interface, node-by-node configuration and WAN troubleshooting. In order to ensure timely completion of the exam, the use of notepad (scripts) and CLI shortcuts was imperative.
15 years later, many of us still manage our WAN’s in the same way: using text files, simple automation tools and scripting engines on a node-by-node basis. While this is reasonably effective on a small-scale network, similar to Metcalfe’s Law, the complexity of the network is equal to the number of nodes on the network, squared.
Today, application, cloud, security and other imperatives require the WAN to be dynamic and flexible to meet business needs. The agility and frequency of change the WAN requires is increasing exponentially. In addition, the price/performance of broadband relative to private lines (MPLS/Frame Relay) and the availability of cellular (3G/4G/LTE) has encouraged the adoption of hybrid architectures reducing cost, but increasing complexity. The business is asking IT to do more with less, leverage existing hardware to contain costs, support past and future applications, and be more agile. In order to keep up with these transitions and business requirements, the enterprise needs better tools. Read More »

Today, I am pleased to announce that we will be showcasing the Cisco Intelligent WAN (IWAN) Application for the APIC-EM controller with early adopter customers at Cisco Live San Diego next week. For those of you familiar with Cisco’s SDN solutions, the APIC-EM builds on Cisco’s ACI architecture to extend Software Defined Networking from the Data Center to the WAN and Access areas of your network.
Before diving into the IWAN App, you might be wondering what is “Software Defined Networking for the WAN” or “SD-WAN” is. The simple answer is that the same benefits that SDN brings to the Data Center can be applied to the Wide Area Network. SDN for the WAN is all about moving from feature by feature configuration to policy and intent driven management. Benefits achieved include reduced costs to operate the WAN and optimize bandwidth. It’s about improving your application experience, enabling digital experiences in your remote branches, and enabling you to move to cloud based applications without giving up on application performance. Finally, it’s about WAN resiliency. Crucially, you must achieve all of this while maintaining end-to-end security and this requires enhancing security capabilities.
Sounds like a lot? It is, and that’s why we (and most of the industry) are so excited about the changes happening in the WAN. To boil it down, as I talk to customers about evolving their WAN architecture to meet the growing bandwidth and performance demands generated by mobile devices, digital stores, cloud based applications, and IoT sensors – to name a few – customers are focused on a short list of business outcomes:
- Greater business agility with faster application delivery
- Reducing costs with simplified operations and management
- Improving business continuity with high availability and resiliency
If these business outcomes sound familiar it is because we are addressing them today with our Intelligent WAN Solution (IWAN) and have been talking about them for the past few years. What’s unique about Cisco is that we have built IWAN to be integrated with our industry leading ISR and ASR 1000 routers while many others have chosen to go with a pure overlay. By combining the strengths of IOS XE software with rock solid hardware to provide detailed visibility across all layers of the network, the Cisco IWAN solution has a much more intimate understanding of network conditions and can make better and faster decisions about how to direct traffic over the WAN. IWAN also retains all of the inherent resiliency, security, and self-healing aspects that routing protocols were developed to provide. Combine this with Cisco’s industry-leading security portfolio as well as our end-to-end vision for policy based infrastructure (ACI) and we have a solution is pretty hard to beat. Read More »
