Show 340: OpenFlow, Fabrics & Network Virtualization

Todays Weekly Show is a wide-ranging discussion on OpenFlow (and what happened to it), network disaggregation, & network virtualization. Our guest Wes Felter and the Packet Pushers explore the current state of networking and speculate about where the industry is going. The post Show 340: OpenFlow, Fabrics & Network Virtualization appeared first on Packet Pushers.

Pockethernet – A Smartphone-Enabled Cable/Link/IP Tester

I saw an advertisement for Pockethernet a few months ago and it looked pretty impressive; €167.23 (~$179 based on xe.com‘s published exchange rates at the time of writing) for a 200 gram rechargeable device offering 10/100/1000 Ethernet and cable testing features such as:

  • A cable tester (wiremapping, TDR fault detection, PoE testing, BER and an analog toner)
  • Link analyzer (speed, duplex, VLAN tags, CDP/LLDP, traffic detection)
  • IP analyzer (DHCP, DNS, HTTP, ICMP ping)
  • Report generation

Over all, Pockethernet sounded like something I needed to look into more closely.

Pockethernet

Pockethernet started off with the assistance of a crowdfunding campaign on Indiegogo, raising $185,000 of their $50,000 target. Unusually for an electronic device, Pockethernet is manufactured in Hungary, which was nice to see. Unboxing the Pockethernet I was surprised (but pleased) to discover that the device is packaged in a soft, zipped carry case.

The box also contains a small User Guide, and inside the case is the Pockethernet tester, an adaptor, a short Ethernet cable and a short USB charging cable. There’s also a strip of blue velcro which will be useful to hold the tester in place if needed.

IDG Contributor Network: Veeam aims for continuous availability with Availability Suite v10

Veeam Software has been busy at its VeeamON user conference in New Orleans this week. During the event, the company talked about how it supports the "always on enterprise" and how it is helping enterprises support the transition to supporting the "digital life."The company's new Veeam Availability Suite v10 is designed to, in the company's words, "provide non-stop business continuity, digital transformation agility and analytics and visibility."Veeam Availability Suite v10 Here's what the company has to say about this new version of its software:This platform protects: Physical servers and Network Attached Storage (NAS). Tier-1 applications and mission-critical workloads with NEW Veeam CDP (continuous data protection), bringing recovery SLAs of seconds using continuous replication to the private or managed cloud. Native object storage support, freeing up costly primary backup storage with policy-driven automated data management to reduce long-term retention and compliance costs. This includes broad cloud object storage support with Amazon S3, Amazon Glacier, Microsoft Azure Blob and any S3/Swift compatible storage.

Raspberry Pi, ultrasonics, and music

My son is a musician and he’s mentioned several times that he’d like to get an instrument called a  theremin. If you haven’t encountered this instrument before, it consists of an antenna that the theraminist (yes, that is a real word) waves their hand around. The device responds with a musical tone that’s dependent on how close the theraminist’s hand is to the antenna. How does it actually work? According to Wikipedia: The theremin uses the heterodyne principle to generate an audio signal. The instrument's pitch circuitry includes two radio frequency oscillators set below 500 kHz to minimize radio interference. One oscillator operates at a fixed frequency. The frequency of the other oscillator is almost identical, and is controlled by the performer's distance from the pitch control antenna. /  The performer's hand acts as the grounded plate (the performer's body being the connection to ground) of a variable capacitor in an L-C (inductance-capacitance) circuit, which is part of the oscillator and determines its frequency.To read this article in full or to leave a comment, please click here

Why IT service providers are investing in North America

IT service providers set up more new IT delivery centers in North America than anywhere else in the world last year, according to new research.North American locations accounted for more the one-third of new delivery sites (29 out of a total of 76) established by service providers in 2016, according to a report from IT and business sourcing consultancy and research firm Everest Group.The need to be close to U.S. customers coupled with the increased use of automation to control costs is making North America a more attractive option for service delivery, says Everest Group.[ Related: IT service providers increase investment in onshore locations ] The demand for digital transformation related technologies specifically is driving interest in certain metropolitan areas. The share of digital services being delivered in new service provider set-ups has been steadily increasing from approximately 25 percent in 2012 to 63 percent in 2016. “This percentage is expected to continue to remain high as service providers focus on expanding and broadening their digital capabilities,” says Everest Group Vice President Salil Dani.To read this article in full or to leave a comment, please click here

The modern guide to staying safe online

The internet can be a scary place. Threats come in many forms, lurking in practically any corner. Worse, yesterday’s prevailing advice for staying safe online -- avoid dodgy websites, don’t traffic in stolen or illegal goods, interact only with people you know -- no longer holds. Phishing emails from supposed family members, spyware piggybacking on legitimate apps, well-known sites hijacked with malicious code -- digital safety clearly needs new rules to meet today's evolving threatscape.Considering how much of our digital lives occurs online -- communications, financial transactions, entertainment, work, education, to name a few -- adopting even a few safe browsing practices can lead to broad benefits. And this includes how we deal with email messages as well, given how popular email is as a delivery mechanism for online attacks using exploit kits and malware.To read this article in full or to leave a comment, please click here

Apple reportedly working on watch-based glucose monitor

According to reports, Apple has some big plans in store for the Apple Watch. Hardly a surprise, since the company seems intent on positioning its increasingly popular wearable as a health-oriented device.Just a few months ago, word emerged that Apple has been busy hiring a slew of researchers, biomedical engineers and scientists who are working on coming up with a way for diabetics to non-invasively measure their glucose levels. Of course, the challenges Apple faces in making this a reality are immense. Indeed, many biotech companies have been trying to solve this same problem for decades, albeit unsuccessfully.Recently, word surfaced via CNBC that Apple CEO Tim Cook is already test-driving a device capable of tracking his blood sugar.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Use wired networks for Gigabit, not Wi-Fi

Thousand megabit broadband is a turning point for internet delivery speeds. Newer tech, such as virtual reality, and the incumbents, such as video streaming, will benefit. Right now, though, only about 17 percent of the U.S.’s population has access to those super-fast speeds, which are primarily delivered by fiber, according to Viavi Solution’s latest Gigabit Monitor report.Although Gigabit is kicking in, it’s not going to be particularly simple to implement at the networking level, internet metrics company Ookla said earlier this month. Upgraded, wired installs will likely handle the throughput better than existing, now commonly used Wi-Fi, among other things, the company said.To read this article in full or to leave a comment, please click here
