Show 224 – HTTP2. Its The Biggest (Network) Thing Happening on the Internet Today – Repost

HTTP/2 is now submitted to the RFC Editor and will bring major changes to networking. Efficient design means smaller firewalls, less bandwidth and faster response times for users. And the default to encryption means that transparent caches, proxies, IDS/IPS and other network security systems will be seriously impacted.

Network Dictionary – Whitebrand Ethernet

Whitebrand is a term used to describe a type of Ethernet switch that is a whitebox or generic manufacture but sold by a known IT brand. Juniper OCX1100, HP Open Network Switches are example. White-Box Switching + Vendor Branding = Whitebrand switching.  The other term used is “britebox” but this sounds like dishwashing liquid or something you […]

Vendors lay groundwork for 5G with greener and faster mobile networks

A new generation of mobile network equipment comes with lofty promises of better coverage and performance for subscribers, by making it easier for operators to add more capacity and support for new radio technologies.Mobile operators are facing a number of challenges, starting with building networks that won’t get overwhelmed by traffic growth mainly driven by video. The most straightforward way of doing this is adding more spectrum—or lanes, if you will—to their networks. It isn’t a coincidence that the recent AWS (Advanced Wireless Service) spectrum auction in the U.S. was a blockbuster and that operators want to use Wi-Fi frequencies for LTE.To read this article in full or to leave a comment, please click here

Extracting the SuperFish certificate

I extracted the certificate from the SuperFish adware and cracked the password ("komodia") that encrypted it. I discuss how down below. The consequence is that I can intercept the encrypted communications of SuperFish's victims (people with Lenovo laptops) while hanging out near them at a cafe wifi hotspot. Note: this is probably trafficking in illegal access devices under the proposed revisions to the CFAA, so get it now before they change the law.

The Cisco CNPES Cert, First Exam (600-504) and Course

Do you think of yourself as a network engineer? Cisco’s Network Programmability Engineer Specialist (CPNES) certification represents Cisco’s first crack at a certification focused on network engineering in an SDN world. Today’s post begins to examine this certification by looking at the first of the two required exams: the 600-504 NPENG exam. We’ll look at both the exam and a related video course.

Other posts in this series:

• Introduction to Cisco’s SDN Certifications
• Cisco Network Programmability (SDN) Intro Course

Overview

First, to set the stage, Cisco currently offers four network programmability certifications. Loosely you can think of these as two networking-focused certs, and two development-focused certs, based on job roles. For the two networking-focused certs, one focuses on design, while one (the one discussed here) looks at engineering and implementation.

Figure 1: Overview of Cisco SDN Certifications

 

Today’s post focuses on the cisco network programmability engineering specialist (CNPES) cert, and specifically the first exam: the 600-504 NPENG exam. Basically, the NPENG exam covers SDN implementation but excludes ACI, while the second required exam, 600-512 NPENGACI, includes ACI.

This list provides the links for more details – for the certification, each of the two exams, and each of Cisco’s two Continue reading

Lenovo PCs ship with adware that puts computers at risk

Some Windows laptops made by Lenovo come pre-loaded with an adware program that exposes users to security risks.The software, Superfish Visual Discovery, is designed to insert product ads into search results on other websites, including Google.However, since Google and some other search engines use HTTPS (HTTP Secure), the connections between them and users’ browsers are encrypted and cannot be manipulated to inject content.To overcome this, Superfish installs a self-generated root certificate into the Windows certificate store and then acts as a proxy, re-signing all certificates presented by HTTPS sites with its own certificate. Because the Superfish root certificate is placed in the OS certificate store, browsers will trust all fake certificates generated by Superfish for those websites.To read this article in full or to leave a comment, please click here

How machine learning ate Microsoft

At the Strata big data conference yesterday, Microsoft let the world know its Azure Machine Learning offering was generally available to developers. This may come as a surprise. Microsoft? Isn't machine learning the province of Google or Facebook or innumerable hot startups?In truth, Microsoft has quietly built up its machine learning expertise over decades, transforming academic discoveries into product functionality along the way. Not many businesses can match Microsoft's deep bench of talent.[ See what hardware, software, development tools, and cloud services came out on top in the InfoWorld 2015 Technology of the Year Awards. | Download the entire list of winners in the handy Technology of the Year PDF. | Stay up on key Microsoft technologies with InfoWorld's Microsoft newsletter. ] Machine learning -- getting a system to teach itself from lots of data rather than simply following preset rules -- actually powers the Microsoft software you use everyday. Machine learning has infiltrated Microsoft products from Bing to Office to Windows 8 to Xbox games. Its flashiest vehicle may be the futuristic Skype Translator, which handles two-way voice conversations in different languages.To read this article in full or to leave a comment, please click here

The cloud journey continues: HP and Cumulus Networks

Is open networking mainstream?

If the HP announcement of new data center networking solutions with Cumulus Linux is any indication, then we will venture to answer.

Yes.

On Feb. 19, HP announced a partnership with Cumulus Networks for new HP open network switches with Cumulus Linux, the operating system for open networking. HP has designed an efficient supply chain model including a joint venture with Accton, delivery worldwide via HP logistics centers, and HP local sales and support.

Open networking was born when web-scale providers developed proprietary cloud networking that reduced CapEx costs while improving OpEx and enabling automation.  Similarly, hosting companies, service providers and high-tech firms re-architected their data centers realizing similar benefits.  Next, financials, government, and education entities found affordable capacity and new innovation opportunities with their cloud journey.  Today, a broad range of enterprises are adopting open networking for a wide set of use cases – and for automation and rapid service delivery using Linux tools already standardized for servers.

In that context, the new HP open network switch offerings with Cumulus Linux address a range of use cases but the sweet spot is hyper-scale data center operators. Of course HP also offers the servers, storage and Continue reading
