IDG Contributor Network: Digital transformation of cities: Creating smart and engaged communities with IoT

What makes a city a “smart city?” Some would argue that it has to do with the degree to which the city is staying abreast of technology advancements, but that is too one-dimensional. Smart cities require an integrated approach to IoT, connectivity, AI, distributed computing and other technologies.To truly capitalize on smart city technology, technologists must understand the immediate and long-term pain points for city governments; the procurement framework including budgetary and funding issues; and the overall bureaucratic and legislative processes.An integrated approach to technology implementation – cutting across all departments in the city – can help alleviate specific challenges such as parking management, traffic management, street lighting, energy consumption (and demand response), and public safety.To read this article in full, please click here

BrandPost: What Is an Autonomous Network?

Automation itself, and the idea that technologies could be self-provisioning, self-diagnosing, and self-healing, has been around for some time. But with advances in Artificial Intelligence (AI) and cloud technologies, such fanciful notions are quickly becoming realities.Nowadays, most of us use AI-enabled apps when we ask Apple’s Siri or Amazon’s Alexa for help with a task. And even streaming services like Netflix help us pick movies and TV shows using AI.WHITE PAPERIntroducing the Adaptive Network VisionTo read this article in full, please click here

Empowering Education for the Next Generation In Paraguay

Colegio Técnico National (CTN) of Asunción is one of the top schools in Paraguay offering the technical baccalaureate. It was created by the country’s Ministry of Education and Science in 1980. The school is attended by more than 1,500 students from the capital city and from nearby towns like Luque, Fernando de la Mora, San Lorenzo, Lambaré, and Capiatá.

As with most of Paraguayan state schools, the CTN does not have the right infrastructure for an appropriate development of modern education. The little equipment owned by the CTN, donated more than 25 years ago by private or charitable institutions, are today too obsolete. Classes do not have any type of interactive material due to the lack of an Internet connection, equipped laboratories, and modern computers. A new project lead by the Paraguay Chapter and supported by the Internet Society Beyond the Net Funding Programme will provide the school with Internet access and set up a high-tech electronics lab to ensure a quality environment for the development of innovative solutions based on robotics, automation, e-learning systems, and the Internet of Things. 250 students will be trained in the use of online tools. ReVa , a virtual library, will be available Continue reading

Companies ready to spend on IT hardware again

In-house IT hardware spending has been on hold thanks to executives flip-flopping on whether to move to cloud computing. It hasn't been because they've actually shifted to cloud services.The problem has been merely inertia caused in companies by "decision-making around the cloud," says Morgan Stanley in a new financial research note published this week. The financial services firm suggests that once enterprises complete their cloud assessments, their checkbooks will open once more.Also read: Top 10 data center predictions: IDC In fact, Morgan Stanley, which advises people on industry investments, says investors could see double-digit earnings growth from the IT hardware sector in 2018. And it has upgraded its fiscal view from "cautious" to "attractive."To read this article in full, please click here

NetDevOpEd: Demand more from your vendors

I was at the London Network Automation meetup this past week. London has a great community of network engineers that are eager to improve their current skill set and make their work lives easier. This meetup was geared towards learning new technologies around automation in the networking industry. There were talks about new ways to implement various existing automation tools, as well as real world discussions around how automation was implemented in the industry.

One common theme I experienced was how eager all network engineers are to open the scripts and code they write to administer their network devices. The sense of community and camaraderie amongst peers in this industry is one of the reasons I really enjoy working in this field. This is a real change in the industry. Even one year ago, the majority of network engineers did not have accounts on github or gitlab. Now, all these same network engineers exchange github and gitlab accounts like business cards. I couldn’t be happier with the direction this industry has taken.

However, I also couldn’t help but think about the irony of this situation. These creative and intelligent engineers are creating innovative scripts to shoehorn solutions into closed systems. Continue reading

Leveraging Windows Server 2016 for hyperconvergence

With the release of Microsoft Windows Server 2016 a couple years ago, Microsoft directly entered the hyperconverged infrastructure (HCI) platform space that has been served by organizations like Nutanix, Scale, Cisco, HP, Dell, and others — only Microsoft comes at it with a fully software-defined platform rather than hardware and applicances.+RELATEDTop 5 Windows server 2016 features that enterprises are deploying; REVIEW: Deep dive into Windows Server 2016+To read this article in full, please click here

Leveraging Windows Server 2016 for hyperconvergence

With the release of Microsoft Windows Server 2016 a couple years ago, Microsoft directly entered the hyperconverged infrastructure (HCI) platform space that has been served by organizations like Nutanix, Scale, Cisco, HP, Dell, and others — only Microsoft comes at it with a fully software-defined platform rather than hardware and applicances.The underpinnings HCI environments are based on the following: Scalable and Shared Compute: The ability to aggregate processing power beyond a traditional “server” with two or four sockets spanning a finite 24, 32, 64 cores to an array of multiple servers where the core processing capabilities brings together four, eight, 16, or more servers with hundreds of cores that can be shared and allocated to workloads as needed. Scalable and Shared Storage: The core storage component of HCL is very similar to the traditional Storage Area Network (SAN) model of the past decade where dozens of drive subsystems are spanned for high performance and capacity and allocated to workloads as needed. Flexible and Customizable Networking: The networking component of HCI provides virtual networks that isolate traffic and shape communications to optimize the workload to workload communications for performance and security purposes HCI compute on Windows Server 2016 — based Continue reading

BrandPost: How SD-WAN enhances & fortifies security options

Beyond basic network connectivity and network-centric features such as WAN optimization, security has been one of the promised next-wave roadmap features surrounding managed SD-WAN services.In early customer deployments, network connectivity was the spotlight feature, along with managing the mix of network types and diversity of providers. Security was a concern early on, but most customers have realized they can retain their existing security infrastructure and environment with little change. They can also enhance their security measures with the many security options available through managed SD-WAN.To read this article in full, please click here

Create or Edit a File on Cisco IOS Flash

How Does Internet Work - We know what is networking

There is always the option to edit a file locally on your computer in notepad++ and then upload it to Cisco device. With this trick, you can write or edit a file from Flash memory directly from Cisco IOS console. If you need it for whatever reason, maybe to change something in the config file or something else, this is the way to do it. I was using if for my next article lab where I needed a file on the flash with at least 1600 bytes so I can pull it from neighbouring router with HTTP and check some

Lack of Fast Convergence in SD-WAN Products

One of my readers sent me this question:

I'm in the process of researching SD-WAN solutions and have hit upon what I believe is a consistent deficiency across most of the current SD-WAN/SDx offerings. The standard "best practice" seems to be 60/180 BGP timers between the SD-WAN hub and the network core or WAN edge.

Needless to say, he wasn’t able to find BFD in these products either.

Does that matter? My reader thinks it does:

ICANN seeking public comment on Root KSK rollover process for DNSSEC

On 11 October 2018, should ICANN roll the Root Key Signing Key (KSK) that is at the heart of DNSSEC? ICANN is planning to restart the rollover process for the Root KSK and is therefore seeking public review of their new plan.  It includes more publicity about the need to be prepared for the rollover, and analysis of data indicating the level of preparedness.

The Plan for Continuing the Root KSK Rollover describes how ICANN intends to roll the root key signing key (KSK), and is based on input from the technical community following their decision to postpone the rollover last year.

Further input is requested by 2 April 2018. This will be used to prepare a final plan that will be presented to the ICANN Board for approval. ICANN is seeking public comments and we encourage you to read the plan and submit your views.

Learn how to submit your comments to ICANN

The Root KSK was originally planned to be rolled over on 11 October 2017, but ICANN postponed the rollover due to collected data that showed that a significant number of resolvers used by network operators were not ready for this. This meant that significant sections of the Internet could experience Continue reading

BrandPost: 5G, A New Era

Ryan Ding, Huawei Executive Director and President of Carrier Business Group, shared his views and vision for 5G with the industry at the "5G is Now" Summit during the Mobile World Congress (MWC) 2018.During his remarks, Ding noted: "Looking back, we can see how technology has driven social change: 2G kicked off an era of global communications; 3G and 4G brought us mobile internet; and 5G marks the start of a new, intelligent world, with all things sensing, all things connected, and all things intelligent." Huawei supplied Ten years ago, when 4G was still just a pipe dream, it was hardly imaginable that we would be buying plane tickets, booking hotels, ordering taxis, and paying bills… all at the touch of a phone screen. Smartphones are our portals to the digital world. And in the coming 5G world, networks will connect things, as well as people. It will be a world where all things are sensing, all things are connected, and all things are intelligent. We are going to see the emergence of many things that we cannot imagine today. On the roads, self-driving cars will communicate through the 5G network, and traffic jams, accidents, and parking problems Continue reading
