Juniper set to reinforce core edge networking, cloud technologies

There is a fundamental, but perhaps a logical evolution in the way networks are being built to handle hybrid cloud applications – resources are moving closer to the edge; data centers are becoming more distributed and cloud hyperscalers are building bigger backbones to handle that traffic.That is the  overarching networking landscape laid out by  Juniper’s CTO Bikash Koley in an interview this week ahead of the company’s NXTWORK 2019 customer event next month. To read this article in full, please click here

Everything you need to know about 10G, the future of broadband technology

With the emergence of more connected devices and immersive content experiences happening alongside an unparalleled boom of video streaming platforms, there’s never been a more critical time to have a powerful and reliable network than can meet the demands of the future.

Home internet speeds will be 10 times faster than today’s fastest broadband networks, staying ahead of your digital demands, especially as technology becomes even more integral in our day-to-day lives. To read this article in full, please click here

Watson IoT chief: AI can broaden IoT services

IBM thrives on the complicated, asset-intensive part of the enterprise IoT market, according to Kareem Yusuf, GM of the company’s Watson IoT business unit. From helping seaports manage shipping traffic to keeping technical knowledge flowing within an organization, Yusuf said that the idea is to teach artificial intelligence to provide insights from the reams of data generated by such complex systems.Predictive maintenance is probably the headliner in terms of use cases around asset-intensive IoT, and Yusuf said that it’s a much more complicated task than many people might think. It isn’t simply a matter of monitoring, say, pressure levels in a pipe somewhere and throwing an alert when they move outside of norms. It’s about aggregate information on failure rates and asset planning, that a company can have replacements and contingency plans ready for potential failures.To read this article in full, please click here

IDG Contributor Network: JEDI award signals a critical ‘perception of parity’ in the cloud wars

AWS, Amazon’s cloud business, has enjoyed a long run as undisputed heavyweight champion of the cloud wars. With revenue run rate nearing 36 Billion and continuous double-digit market growth it was difficult to see anyone catching up. Until just like that, in the blink of an eye, a $10 Billion Federal cloud contract for the DoD known as JEDI (Joint Enterprise Defense Infrastructure) was awarded to Amazon’s crosstown rival, Microsoft. With this award, I believe the game has changed, and the market perception of such a substantial win will provide Microsoft the opportunity to apply significant pressure to AWS’s number one market position.This week’s earnings may have been the first domino Microsoft has been on an unparalleled run, and this past week the company delivered well above expectations on earnings coming in at $1.38 per share vs. $1.25 expected while also substantially beating revenue targets by nearly $800 million at $33.06 Billion. The cloud business, Azure, grew 59%*, which was actually viewed as a mooted result compared to previous quarters in the 60-70% range, but with margins up, revenues up and earnings up, Microsoft is flying high.To read this article in full, please click here

As the internet turns 50, experts weigh future advances and emerging issues

As the internet turns 50, the technology is only picking up steam and continuing to reinvent many aspects of our lives, from the way we do business, and the way we find dates and jobs, to the way we run for political office.  The internet was born when the first Arpanet link was established between the University of California, Los Angeles and the Stanford Research Institute at 22:30 hours on October 29, 1969. UCLA professor Leonard Kleinrock and his student Charley Kline sent the first message to Bill Duval, a programmer at Stanford University. That first communication was the spark that ignited the growth of the internet and everything it has brought with it – email, sharing pictures on Facebook, buying books and toasters on Amazon, watching movies on Netflix, cat videos, mean-spirited memes and election-tampering bots.To read this article in full, please click here

How SD-WAN is evolving into Secure Access Service Edge

SASE, pronounced "sassy," stands for secure access service edge, and it's being positioned by Gartner as the next big thing in enterprise networking. The technology category, which Gartner and other network experts first introduced earlier this year, converges the WAN edge and network security into a cloud-based, as-a-service delivery model. According to Gartner, the convergence is driven by customer demands for simplicity, scalability, flexibility, low latency, and pervasive security.SASE brings together security and networking A SASE implementation requires a comprehensive technology portfolio that only a few vendors can currently deliver. The technology is still in its infancy, with less than 1% adoption. There are a handful of existing SD-WAN providers, including Cato Networks, Juniper, Fortinet and Versa, that are expected to compete in the emerging SASE market. There will be other SD-WAN vendors jumping on this wagon, and the industry is likely to see another wave of startups. To read this article in full, please click here

IoT roundup: Carriers expand NB-IoT footprints, Congress eyes security bill, and ‘IT asbestos’ looms

The major U.S. mobile carriers are eager participants in the rise of IoT, and it’s tough to argue that they don’t have a major role to play – the ability to connect largely anywhere, coupled with the ability to handle high-throughput applications, means that cellular data can be an attractive option for the connectivity piece of an IoT deployment.AT&T announced a deal with Vodafone last week to interconnect their respective narrow-band IoT networks across the Atlantic, mating AT&T’s U.S. coverage with Vodafone’s in western Europe. That means that businesses with NB-IoT deployments in those areas can use that single network to connect their entire implementation. Not to be outdone, Sprint announced that it, too, is rolling out NB-IoT on its Curiosity IoT platform. Sprint shared its plans during a panel discussion at Mobile World Congress in Los Angeles last week.To read this article in full, please click here

NICT successfully demos petabit-per-second network node

Petabit-class networks will support more than 100-times the capacity of existing networks, according to scientists who have just demonstrated an optical switching rig designed to handle the significant amounts of data that would pour through future petabit cables. One petabit is equal to a thousand terabits, or a million gigabits.Researchers at the National Institute of Information and Communications Technology (NICT) in Japan routed signals with capacities ranging from 10 terabits per second to 1 petabit per second through their node. Those kinds of capacities, which could send 8K resolution video to 10 million people simultaneously, are going to be needed for future broadband video streaming and Internet of Things at scale, researchers believe. In-data-center applications and backhaul could benefit.To read this article in full, please click here

How IT pros deal with SD-WAN security concerns

SD-WAN technology is becoming increasingly popular because it's less expensive, more flexible and easier to deploy than MPLS, it provides centralized visibility and management, and it boosts the overall performance of WAN links, which makes employees more productive. But enabling end users in branch offices to connect directly to the public internet and to cloud services raises serious security concerns, which adds another level of complexity and risk to an SD-WAN rollout. To read this article in full, please click here(Insider Story)

Google claims quantum supremacy over supercomputers

The results of an experiment performed on Google’s Sycamore quantum computer demonstrate that theoretical quantum computing designs can work as expected, the company announced today in a paper published in the journal Nature.Formulating the problem was the first hurdle. The company’s research team eventually settled on comparing the Sycamore computer’s output to that of a modern, classical supercomputer in the task of reading the state of a pseudo-random quantum circuit. This results in a computational challenge that should be comparatively simple for Sycamore, but enormously difficult for a supercomputer equipped with traditional silicon.To read this article in full, please click here

BrandPost: MPLS Migration: How a KISS Transformed the WANs of 4 IT Managers

Back in 1960, a Lockheed engineer named Kelly Johnson coined the acronym KISS for “keep it simple stupid.” His wise—and simple—advice was that systems tend to work better when they’re simple than when they’re complex. KISS became an essential U.S. Navy design principle and captures the crux of any WAN transformation initiative.So many of the challenges of today’s WANs stem from the sheer number of components involved. Each location may require one or more routers, firewalls, WAN optimizers, VPN concentrators, and other devices just to connect safely and effectively with other locations or the cloud. The result: multiple points of failure and a potential uptime and troubleshooting nightmare. Simply understanding the state of the WAN can be difficult with information spread across so many devices and components. Managing all the updates required to protect the network from new and evolving threats can be overwhelming.To read this article in full, please click here
