Micro-Fiber, Meet Micro-Segmentation! Columbia Sportswear Virtualizes the Network, Saves Millions

With 110 stores in North America, 46 data center locations, and $2 billion in revenue, Columbia Sportswear is constantly processing huge amounts of data—data whose security was being compromised by their inadequate hardware-defined data center.

When Columbia Sportswear virtualized their network, they not only stepped up their security; they also saved $16 million over a comparable hardware-based security approach.

Multiple U.S. trials underway for shared 3.5GHz wireless spectrum

Six technology companies, including Google, are working on trial projects in multiple U.S. cities to test out shared 3.5GHz spectrum wireless communications under an innovative model adopted recently by the Federal Communications Commission.The companies are working in an coalition that is tentatively being called the CBRS (Citizens Broadband Radio Service) Alliance, which borrows the CBRS terminology from the FCC. Some of the companies in the alliance have already demonstrated what they call OpenG technology, which uses 3.5GHz shared spectrum to improve indoor wireless communications.To read this article in full or to leave a comment, please click here

Patent troll wants Apple to shut down iMessage and FaceTime

For some companies, winning $625 million from Apple is not enough of a reward.On Wednesday, VirnetX asked a Texas judge to order Apple to shut down iMessage and FaceTime while their patent case goes to appeal. Previously, VirnetX was awarded $625 million in the case after it convinced the jury that Apple committed patent infringement. If the judge grants the injunction, Apple will be forced to either suspend iMessage and FaceTime or find a last-minute workaround to the patented technology.One of the patents in question involves establishing secure communications through Internet domain names. In asking for the injunction, VirnetX argued that although forcing a company to shut down two of its most popular services may seem excessive, it’s necessary because the infringement has done “irreparable harm” to VirnetX.To read this article in full or to leave a comment, please click here

Wayfair takes augmented reality, Project Tango to the enterprise

Virtual and augmented realities aren't just for gaming.Wayfair Inc. , a Boston-based, 14-year-old e-commerce company that sells home furnishings, is working on an app based on Google's Project Tango technology that would put augmented reality, and one day virtual reality, squarely in the enterprise.If all goes as planned, customers using Wayfair's app would go beyond looking at a photo of a love seat or table, reading the measurements and wondering how the piece would look in their living room.The app would use Project Tango's mapping, computer vision, depth-sensing, 3D-motion tracking and machine-learning technology to allow customers to see – on their Android smartphone or tablet – how a piece of furniture would look in their home.To read this article in full or to leave a comment, please click here

Acer’s Windows 10 Switch hybrids priced to battle Chromebooks

Windows 10 PC prices have been slowly creeping up, but some new back-to-school Switch tablet/laptop hybrid devices from Acer may be attractive to those on a shoestring budget. The US$199 Switch One 10 is one of a few touchscreen hybrids priced under $200. Acer also announced the Switch V 10, which starts at $249 with additional features including a USB-Type C port, a fingerprint reader, 802.11ac Wi-Fi and a Gorilla Glass screen. The hybrids, also known as 2-in-1 devices, are 10-inch tablets that can be latched on to a keyboard dock to become a laptop. The new Switch devices are inexpensive Windows alternatives to Chromebooks, which are laptops with Google's Chrome OS. Acer sells Chromebooks starting at $179.99.To read this article in full or to leave a comment, please click here

Docker Networking: macvlans with VLANs

If you have read my introduction to macvlans and tried the basic macvlan bridge mode network configuration you are aware that a single Docker host network interface can serve as a parent interface to one macvlan or ipvlan network only.

One macvlan, one Layer 2 domain and one subnet per physical interface, however, is a rather serious limitation in a modern virtualization solution. Fortunately, a Docker host sub-interface can serve as a parent interface for the macvlan network. This aligns perfectly with the Linux implementation of VLANs, where each VLAN on a 802.1Q trunk connection is terminated on a sub-interface of the physical interface. You can map each Docker host interface to a macvlan network, thus extending the Layer 2 domain from the VLAN into the macvlan network.

Multiple macvlans with VLANs configuration

You have a Docker host with a single eth0 interface connected to a router. Connection between the router and the Docker host is configured as 802.1Q trunk on the router with VLAN 10 and VLAN 20.

Configure VLAN 10 and VLAN 20 on your router. Add the following IP addresses to the Layer 3 interface: 10.0.10.1/24 and 2001:db8:babe:10::1/64 for VLAN 10, 10. Continue reading

Juniper’s new access switches add to its cloud-focused lineup

Juniper Networks’ Unite architecture is living up to its name, bringing more enterprise network gear into its system for simplified management and scaling.The latest additions to the lineup are entry-level and midrange access switches that also include other features for ease of use.Unite, introduced last year for the EX9200 core switches and other Juniper and third-party components, is designed to help enterprises turn their own infrastructure into private clouds and link those to public clouds in a hybrid architecture. It’s built around Junos Fusion Enterprise software, which collapses multiple network layers into one for simpler management. That gives administrators a single point of management.To read this article in full or to leave a comment, please click here
