Geneve

One of the various problems we face in the data networking world is the absolute plethora of tunneling technologies we have available. Going way back to the beginning, there was SNA, GRE, IP-in-IP, and a host of others. In the midterm was have MPLS (though some will argue this isn’t a tunneling protocol — but […]

Old-school anti-virus vendors learn new tricks

In an era when businesses are scrambling to defend against sophisticated advanced persistent threats, old school anti-virus may seem like a relic. But traditional anti-virus companies are changing with the times, delivering defense-in-depth for a BYOD world.In this review, we looked at products from seven of the original anti-virus vendors, each dating back to at least the 1990s: AVG, ESET, Kaspersky, McAfee, Symantec, Panda Software and Trend Micro. We focused on ease of installation and management, ease of use, plus the protection each suite offered beyond traditional signature-based anti-virus. Special emphasis was placed on the software’s ability to also protect mobile devices running both iOS and Android.

Chinese smartphone market shows rare shipment decline

The world’s largest smartphone market, China, isn’t so hungry for the products anymore.First quarter smartphone shipments there dropped by 4 percent year over year, according to research firm IDC. It’s the first time in six years that China’s smartphone market has contracted, signifying that the country’s appetite for the handsets is reaching its limit.The number of shipments to China was still high, at 98.8 million units. IDC expects the market to remain flat for the rest of the year. To drive future growth vendors in the country will have to convince existing users to upgrade to newer phones, IDC said.To read this article in full or to leave a comment, please click here

BGP AIGP

In this post we will look at something which is relatively new but not as cool as my previous post on Segment Routing. We will take a look at a new BGP feature called “Accumulated IGP, metric of path to prefix” (RFC 7311 AIGP)  which is an optional non-transitive attribute . A new AIGP TLV was created for this which contains […]

Do We Need Network Programmability?

Jsicuran left this comment on my You Must Understand the Fundamentals to Be Successful blog post:

I just went through some Cisco webinar where they were showcasing the use of NX-OS API and Python to add a VLAN. I do some Python myself and have used that API for some simple DevOps-like uses, but for the most part if you are an enterprise and use Prime DCIM to add VLANs, why should you go through the coding process?

It obviously depends on where you are in your IT automation journey.

IBM’s flexible Power servers can take on cloud, databases

IBM is building slimmer versions of its Power hardware—used by its Watson supercomputer—to run complex database applications as well as simpler Web-based ones.IBM has designed its latest Power servers for social networking, search engines and cloud storage, as computing moves from PCs to mobile devices. Beyond the cloud, the new servers with Power8 chips also have the horsepower to handle more complex applications like databases and analytics.The multipurpose servers include the four-socket Power E850, which can handle private, public and hybrid clouds, and in-memory database applications. The more powerful Power E880 is for large-scale database and cloud implementations.To read this article in full or to leave a comment, please click here

OSPF Path Selection Challenge

I had an interesting question come across my desk today which involved a very common area of confusion in OSPF routing logic, and now I’m posing this question to you as a challenge!

The first person to answer correctly will get free attendance to our upcoming CCIE Routing & Switching Lab Cram Session, which runs the week of June 1st 2015, as well as a free copy of the class in download format after it is complete.  The question is as follows:

Given the below topology, where R4 mutually redistributes between EIGRP and OSPF, which path(s) will R1 choose to reach the network 5.5.5.5/32, and why?

Bonus Questions:

• What will R2′s path selection to 5.5.5.5/32 be, and why?
• What will R3′s path selection to 5.5.5.5/32 be, and why?
• Assume R3′s link to R1 is lost.  Does this affect R1′s path selection to 5.5.5.5/32? If so, how?

Tomorrow I’ll be post topology and config files for CSR1000v, VIRL, GNS3, etc. so you can try this out yourself, but first answer the question without seeing the result and see if your expected result matches the actual result!

 

Good luck everyone!

10 Examples of how to get Docker Container IP Address

One thing that is so much fun about the need virtualization paradigm we are heading towards is that in the age of “software defined”, the flexibility of how to do things with infra are much more like programming then working with highly opinionated traditional infrastructure. Along that thread, here are 10 different ways to get a container or docker-machine address ...

Eccentric 21st Century LED lighting with Bluetooth and smartphone apps

You’re sitting in your office (or cube) and it’s kinda drab. You need something to brighten it up and I have just what you might want: Lamps. But these are no ordinary lamps, these are LED lamps called Notti and Dotti produced by Witti Design which you can program from your smartphone and they are kind of eccentric. The Notti is a white truncated prism (100mm high by 75mm wide by 60mm deep) with rechargeable batteries. It can be programmed via an iOS or Android app and connects via Bluetooth BLE. The Notti can continuously change color, change color according to the music being played on your smartphone, stay on a fixed color, gradually brighten in alarm mode to wake you up, or light up when your smartphone receives a message or you get an incoming call. The battery lasts 720+ hours in notification mode (off until a notification event occurs) or 5+ hours in continuous mode.To read this article in full or to leave a comment, please click here
