The U.S. Postal Service is set to purchase GPU-accelerated servers from Hewlett Packard Enterprise that it expects will help accelerate package data processing up to 10 times over previous methods.The plan is for a spring 2020 deployment, using HPE's Apollo 6500 servers, which come with up to eight Nvidia V100 Tensor Core GPUs. The Postal Service also will use Nvidia's EGX edge computing servers at nearly 200 of its processing locations in the U.S.

Whether you’re switching from MPLS or Internet VPNs, SD-WAN can jumpstart network performance, agility, and scalability, particularly for cloud applications. However, as with any migration, there can be challenges and surprises. Don’t squash productivity with unplanned outages or security breaches. Plan your migration carefully, ask the right questions, and cover your bases. Here are some key pitfalls to avoid from those who’ve been there.Security Should Work with Your SD-WAN
If you’re used to backhauling cloud traffic through data-center security via MPLS, you’re bound to see a big boost in branch office cloud performance using direct Internet access. However, bypassing data-center security means you must find a way to deliver the same level of security at the branch-office level or risk a data breach. Last year, enterprises with completed SD-WAN deployments were 1.3 times more likely to experience a branch-office security breach than without, Shamus McGillicudy, Research Director at analyst firm Enterprise Management Associates reported on a recent webinar.To read this article in full, please click here
It seems the latest buzzword coming from those analysts at Gartner is SASE (pronounced “sassy”), which stands for “Secure Access Service Edge.” Network World has published several articles recently to explain what SASE is (and perhaps isn’t). See Matt Conran’s The evolution to Secure Access Service Edge (SASE) is being driven by necessity as well as Zeus Kerravala’s article How SD-WAN is evolving into Secure Access Service Edge.To read this article in full, please click here
Juniper has enhanced its network and hybrid cloud management software by integrating further the AI technology it recently acquired from Mist and adding new features to its Contrail Enterprise Multicloud software.The company recently closed the agreement to buy wireless-gear-maker Mist for $405 million and promised to meld the Mist technology with Juniper’s. Mist is known for its cloud-managed artificial-intelligence-based wireless service called WiFi Assurance that measures performance and service-level metrics to make wireless networks more predictable and reliable, the company said.To read this article in full, please click here
The advantages of SaaS applications and other cloud services has businesses rethinking their traditional router-centric WAN strategy. That’s because many of today’s business-critical applications carry the twin challenges of needing high performance, especially for latency-sensitive applications such as unified communications, combined with high volumes of data. These requirements can quickly swamp traditional WAN connections that backhaul data and transactions through the data center. Without the ability to connect directly to the internet, application speeds slow and performance suffers.The other challenge is that routers generally only view data at the packet level, with little to no intelligent recognition or prioritization of business applications. As a result, mission-critical SaaS applications must not only compete for bandwidth with other business data, but also with non-essential traffic such as YouTube videos or Spotify streams. Without the ability to recognize, prioritize, and steer connections to business-critical SaaS applications, it’s all just data going in and out of the branch routers. The result is lowered application functionality, user experience, and business results.To read this article in full, please click here

We are seeing it from all sides now. From the usual suspects in OEM to HCI to virtualization to public cloud, everyone is out to address the growing demand to shift legacy IT workloads to agile, cloud native, consumption-based, hybrid-friendly, modernized IT environments. A mouthful perhaps, but that doesn’t make it any less true. We have entered a multi-cloud world, and the competition is going to be abundant.The question that’s top of mind for many is which company or companies will emerge as the market leader. This week at Ignite, Microsoft’s annual customer conference, the company made a number of announcements around its Azure Cloud. Based on those announcements and the company’s existing platform of services, I wanted to break down how I see Microsoft’s Azure strategy evolving and share what business and IT leaders need to be thinking about when they are looking at modernizing their IT to support the growing multi-cloud initiative.To read this article in full, please click here

Today the telecom industry has identified the need for faster end-user-data rates. Previously users were happy to call and text each other. However, now mobile communication has converted our lives in such a dramatic way it is hard to imagine this type of communication anymore.Nowadays, we are leaning more towards imaging and VR/AR video-based communication. Therefore, considering such needs, these applications are looking for a new type of network. Immersive experiences with 360° video applications require a lot of data and a zero-lag network.To give you a quick idea, VR with a resolution equivalent to 4K TV resolution would require a bandwidth of 1Gbps for a smooth play or 2.5 Gbps for interactive; both requiring a minimal latency of 10ms and minimal delay. And that's for round-trip time. Soon these applications will target the smartphone, putting additional strains on networks. As AR/VR services grow in popularity, the proposed 5G networks will yield the speed and the needed performance.To read this article in full, please click here

There are a lot of options for looping in bash whether on the command line or in a script. The choice depends on what you're trying to do.You may want to loop indefinitely or quickly run through the days of the week. You might want to loop once for every file in a directory or for every account on a server. You might want to loop through every line in a file or have the number of loops be a choice when the script is run. Let's check out some of the options.[Get regularly scheduled insights by signing up for Network World newsletters.]
Simple loops
Probably the simplest loop is a for loop like the one below. It loops as many times as there are pieces of text on the line. We could as easily loop through the words cats are smart as the numbers 1, 2, 3 and 4.To read this article in full, please click here
