Cisco ACI Multipod

Since 2.0, Multipod for ACI enables provisioning a more fault tolerant fabric comprised of multiple pods with isolated control plane protocols. Also, multipod provides more flexibility with regard to the full mesh cabling between leaf and spine switches.  When leaf switches are spread across different floors or different buildings, multipod enables provisioning multiple pods per floor or building and providing connectivity between pods through spine switches.

A new White Paper on ACI Multipod is now available

US tech giants say they didn’t do Yahoo-style email spying

Reports of a secret Yahoo program to search through customers' incoming emails has spurred other tech companies to deny ever receiving a similar request from the U.S. government.The program, reportedly created last year through a classified U.S. order, involves Yahoo searching through hundreds of millions of user accounts at the behest of the National Security Agency or FBI.Other U.S. tech companies, including Google, Microsoft, Twitter and Facebook, denied doing anything like it. Most also said they would challenge such a request in court.Privacy advocates said the government enlisting Yahoo to assist in email monitoring would be wrong.To read this article in full or to leave a comment, please click here

Five questions about taking Google’s new phones to work

Google unveiled a massive strategic shift on Tuesday, announcing that it is officially getting into the business of designing and releasing its own smartphones. The Pixel and Pixel XL, announced at a special event in San Francisco, are the company's first forays into that market after working with outside manufacturers for several years to produce its Nexus line of devices. The phones are snazzy gizmos packed with some of the latest features that Google could come up with, like a new intelligent assistant and a high-quality camera. It feels like one of the best Android smartphones on the market and could be a serious contender to take on Apple's iPhone, especially for people looking to purchase a flagship smartphone.To read this article in full or to leave a comment, please click here

OpenConfig, RESTCONF, and Automated Cable Verification at iNOG9

Last week I was in Dublin for business which just so happened to overlap with iNOG9, which was last Wednesday. As luck would have it, I had the opportunity to speak at iNOG9 about network automation.

You can watch the video if you want to see the presentation, but the three mini demos I gave were:

  1. Cable verification on Juniper vMX devices using Ansible
  2. Automating BGP on IOS-XR using OpenConfig BGP models using Ansible
  3. Using Postman to explore and demo the new RESTCONF/YANG interface on IOS XE.

Few words about each.

Cable verification

Usually when the topic of network automation comes up, configuration management is assumed. It should not be as there are so many other forms and types of automation. Here I showed how we can verify cabling (via neighbors) is accurate on a Junos vMX topology. Of course, the hard part here is having the discipline to define the desired cabling topology first. Note: links for sample playbooks can be found below on the GitHub repo.

OpenConfig BGP Automation with Ansible

I built a custom Ansible module built around NETCONF (ncclient), but uses the OpenConfig YANG model for global BGP configuration. For example, this is the Continue reading

WikiLeaks plans to dump more sensitive files on US election

WikiLeaks is promising to release secret documents relating to the U.S. election, at a time when there are already questions over whether Russian hackers are feeding the site information.WikiLeaks will publish the documents "every week for the next 10 weeks" and the topics include the U.S. election, war, arms, Google, and mass surveillance, site founder Julian Assange said on Tuesday in a press conference.  All the U.S. election documents will be released before Nov. 8, when voters cast their ballots. The leaks pertain to "U.S. power factions and how they operate," Assange said. However, he denied deliberately trying to sabotage Democratic presidential candidate Hillary Clinton's election chances.To read this article in full or to leave a comment, please click here

IBM invests $200 million in Watson IoT AI business

The venerable 105-year-old IBM may be a global company, but while it has operated important labs and offices overseas, its business units have always been headquartered in the U.S. Until December of last year, that is, when it opened the new global headquarters for the IBM Watson Internet of Things (IoT) unit in Munich, Germany. Now, faced with dramatically increasing global demand for Watson IoT solutions and services, Big Blue is doubling down on that investment.On Tuesday, IBM announced a $200 million investment in the Watson IoT headquarters, marking one of the company's largest investments in Europe in its history. The investment is part of the $3 billion IBM has earmarked to bring Watson cognitive computing to IoT. IBM says the move is a response to escalating demand from customers who are looking to transform their operations using a combination of IoT and artificial intelligence technologies.To read this article in full or to leave a comment, please click here

Windows 10 growth comes to screeching stop

Microsoft's Windows 10 beat a retreat last month, losing user share for the first time since its debut more than a year ago.According to U.S. metrics vendor Net Applications, Windows 10 lost half a percentage point in user share during September, ending the month on 22.5% of all personal computers.Windows 10 powered 24.8% of all machines running Windows: The difference between the user share of all PCs and only those running Windows originated with the fact that Windows powered 91% of all personal computers, not 100%.September's decline was the first since Microsoft officially launched Windows 10 in July 2015, and the only since January 2015, months before when Microsoft offered only a preview to beta testers.To read this article in full or to leave a comment, please click here

5G will need small cells, so Nokia is sending in the drones

If you want 5G, there’s a good chance you'll need a small cell nearby to deliver it. Putting up that cell may be hard because of a host of problems, but Nokia Bell Labs thinks it can solve some of them with drones and tiny solar panels.Nokia's F-Cell is an experimental LTE small cell that doesn't need any wires. It gets power from solar panels on its surface and communicates with the carrier's core network over a high-speed wireless connection. No one even needs to climb up on a roof to install it: The company recently delivered an F-Cell to the roof of one of its buildings in Sunnyvale, California, using a drone.F-Cells won’t start showing up everywhere tomorrow, but anything to speed up small-cell deployment could make a big difference when 5G starts going live in 2020. The next generation of cellular will probably require dense networks of small cells to deliver the gigabit speeds being promised, and carriers will face both legal and technical hurdles when they try to put them up.To read this article in full or to leave a comment, please click here

New insulin pump flaws highlights security risks from medical devices

Medical device manufacturer Animas, a subsidiary of Johnson & Johnson, is warning diabetic patients who use its OneTouch Ping insulin pumps about security issues that could allow hackers to deliver unauthorized doses of insulin.The vulnerabilities were discovered by Jay Radcliffe, a security researcher at Rapid7 who is a Type I diabetic and user of the pump. The flaws primarily stem from a lack of encryption in the communication between the device's two parts: the insulin pump itself and the meter-remote that monitors blood sugar levels and remotely tells the pump how much insulin to administer.The pump and the meter use a proprietary wireless management protocol through radio frequency communications that are not encrypted. This exposes the system to several attacks.To read this article in full or to leave a comment, please click here
