Response: Videoconferencing Numbers

IDC published a promo piece about their research into videoconferencing market. From a market segment perspective: Multi-codec telepresence equipment revenue ($23.9 million) was down 44.4% quarter over quarter, but increased 27.4% year over year in 1Q16. Unit shipments were down 47.1% quarter over quarter, but increased 48.8% year over year. Room-based videoconferencing system revenue ($359.6 […]

BGP Best External

BGP Best External is used in Active Standby BGP Topologies. BGP Best External helps for BGP convergence by sending external BGP prefixes which wouldn’t normally be sent if they are not overall BGP best path. There are BGP best internal, BGP best external and BGP Overall best path. BGP Best external in an active-standby scenarios […]

Which company has the most CCDE in the World ?

Which company has the most Cisco CCDE certified engineers in the world? Of course, Cisco  has the most certified engineers across the globe. In this post, I will introduce you to the second company that has the most CCDE engineers in the world outside of Cisco.   I like sharing the Global CCDE List whenever someone […]

Cool Tools roundup: Charging, sweating and keyboarding

As part of my research for the Network World Father’s Day 2016 gift idea slideshow, several companies sent along gadgets for me to try out. While some products made the guide, some didn’t – not because they aren’t good, but because I wanted to pick only one device per vendor.  Ventev For example, I chose the Ventev PowerCell 3015+ charger for the guide, but they also sent me some other cool devices. The Desktop Charging Hub (model s500, $50 - See it on Amazon) is a combination device that will help you recharge a phone, a tablet and at least one other USB device. The circular unit also has two 10-amp outlets, for powering additional devices (like your computer, monitor or perhaps other accessories for your desk). The Charging Hub comes with a 5-foot power cord for optimal desktop placement, and two grooves for resting your tablet and/or phone. It should help clean up an area if you do a lot of recharging.To read this article in full or to leave a comment, please click here

Intel’s data center chief talks machine learning — just don’t ask about GPUs

If you want to get under Diane Bryant’s skin these days, just ask her about GPUs. The head of Intel’s powerful data center group was at Computex in Taipei this week, in part to explain how the company's latest Xeon Phi processor is a good fit for machine learning. Machine learning is the process by which companies like Google and Facebook train software to get better at performing AI tasks including computer vision and understanding natural language. It’s key to improving all kinds of online services: Google said recently that it's rethinking everything it does around machine learning.To read this article in full or to leave a comment, please click here

How Intel turned Thunderbolt from a failure into a success

The third time could be the charm for Intel and its Thunderbolt technology. A year after introducing Thunderbolt 3 at Computex 2015, Intel is finally starting to see success with its high-speed external I/O—enough that even doubters might agree it’s winning.You needn’t look far for signs that Thunderbolt 3 will succeed where its two predecessors failed dismally on the PC. This year’s top-tier laptops from HP and Dell, as well models from MSI, Asus, Razer, and Acer, all prominently feature Thunderbolt 3 ports. Almost all of the high-profile laptops of the last few months have prominently featured Thunderbolt 3 ports.To read this article in full or to leave a comment, please click here

Code red: Health IT must fix its security crisis

The health care industry provides an alluring target for malicious hackers. Personal health information has a much longer shelf life than financial information, making it a major draw for identity thieves. But a new and more troubling threat has arisen: the potential disruption of critical hospital systems by cybercriminals.With a diverse array of digital systems, hospitals have evolved into complex technology operations. Yet they remain singularly ill-prepared to defend against attacks, in part because the multiplicity of systems forms a wider surface area to attack.To read this article in full or to leave a comment, please click here

Tricks that ransomware uses to fool you

Pulling ransomware out of …Image by ThinkstockRansomware quite often targets businesses (for example hospitals) rather than individuals. Corporations have more valuable data and more money for ransom (ransom increases from roughly $500 per computer to $15,000 for the entire enterprise). Cyphort has examined different variants of ransomware to help users get an idea of what might be coming down the Internet pipeline. So keep an eye out for these characteristics before your network is taken hostage.To read this article in full or to leave a comment, please click here

Transforming Silos into Universal Cloud Networking

Transforming Silos into Universal Cloud Networking

We have witnessed a massive shift in the way applications are built and deployed, moving away from siloed IT to seamless workloads, workflows and work-streams. This revolution has changed the fundamental way that networks are architected to enable support of cloud native applications. With these new architectures, one can now automate and provision the entire network with real time agility, ushering in a new class of cloud networks.

32 – VXLAN Multipod stretched across geographically dispersed datacenters

This article focuses on the single stretched Fabric across multiple locations as mentioned in the previous post (31) through the 1st option.

I have been working with my friends Patrice and Max for several months building a efficient and resilient solution to stretched a VXLAN Multipod fabric across two sites. The whole technical white paper is now available and can be accessible here:

One of the key use-case for that scenario is for an enterprise to select VXLAN EVPN as the technology of choice for building multiple greenfield data center pods. It becomes therefore logical to extend VXLAN between distant PoD’s that are managed and operated as a single administrative domain. This choice makes sense as a multipod fabric functionally and operationally is a single logical VXLAN fabric, and its deployment is a continuation of the work performed to roll out the pod, simplifying the provisioning of end-to-end Layer 2 and Layer 3 connectivity.

Technically speaking and thanks to the flexibility of VXLAN, we could deploy the overlay network on top of any Layer 3 architecture within a datacenter.

  • [Q] However, can we afford to stretch the VXLAN fabric as a single fabric without taking into consideration the risks of loosing the whole resources Continue reading

New peripherals are bringing Windows Hello to any Windows 10 PC

Japan's Mouse Computer has developed add-on biometric sensors that will bring Windows Hello to any PC running Windows 10. Windows Hello is Microsoft's biometric security system. It allows users to dump passwords for facial or fingerprint recognition, but only on PCs that have the correct hardware. Many new PCs do, but generations of older machines that can run Windows 10 don't have the infrared camera or fingerprint sensors that are required. That's where the new add-on peripherals come in. There's a USB camera unit and a tiny USB fingerprint reader. Both will bring Windows Hello to Windows 10 PCs, said Microsoft this week at the Computex trade show in Taipei.To read this article in full or to leave a comment, please click here
