Network Engineer Certification in 2018


Last week I was in Mountain View, in a room full of senior Network Engineers, and we were talking about the skills that need to be developed by more junior Network Engineers. Suddenly someone shouted from the back "CCIE!" and the whole room started laughing.

So CCIE is a laughing stock now?

No need to get offended. You have to understand the context here:
These group of people have been working for the best company in the world. They have been working on the most advanced network infrastructure. The company's undersea cables connect all contingents, to delivers 25% of worldwide Internet traffic.


These people didn't develop their skill through certification. They developed their skills by building the real stuff. When these group of Network Engineers realized the network capacity in the company's data centers has grown so fast that conventional routers and switches can't keep up to meet the requirements of its distributed systems, they decided to build its own instead. These Network Engineers build and operate software-defined networking, before the world invented that terminology. They've been automating network operation in Data Center, WAN, Internet Peering, all the way to Wifi and Enterprise networking, to support 7 company's Continue reading

Celebrating the 25th Anniversary of NDSS

This year we are celebrating the 25th anniversary of the Network and Distributed System Security Symposium (NDSS). NDSS is a premier academic research conference addressing a wide range of topics associated with improving trust in the Internet and its connected devices. A key focus of the Internet Society has long been improving trust in the global open Internet. In order to promote this trust, we need new and innovative ideas and research on the security and privacy of our connected devices and the Internet that connects them together.

NDSS 2018 is about to get underway in San Diego, CA (18-21 February). It will be the biggest NDSS symposium yet, featuring 71 peer-reviewed papers, 20 posters, 4 workshops, 2 keynotes, and a co-located research group meeting. Record registration numbers are a key indicator that NDSS 2018 is featuring vital and timely topics. Below are some of the highlights expected in the coming week.

Workshops

This year’s program officially starts with four workshops on Sunday, 18 February. NDSS workshops are organized around a single topic and provide an opportunity for greater dialogue amongst researchers and practitioners in the area. Each of this year’s workshop have dynamic agendas.

The Workshop on Binary Continue reading

Requests for Cisco Catalyst 9300 are up … what’s the intent?

My project engineering staff has been getting more and more information requests for Cisco’s new line of Catalyst 9000 switches, especially the 9300 switch. That has me wondering why.Cisco touts the Catalyst 9300 Series as the next generation of the industry's most widely deployed stackable switching platform that’s built for security, the Internet of Things (IoT), and cloud computing. It’s part of a line of network switches that form the foundation for Cisco's Software-Defined Access, its leading enterprise architecture.One reason for the increased interest could be Cisco’s recently announced new intent-based networking system. Cisco believes that by adopting an intent-based approach, networks will be able to deliver a solution that introduces an onslaught of applications and devices that provide greater efficiency and address new security threats.To read this article in full, please click here

Making Alexa Tech Demos Useful

Technology always marches on. People want to see the latest gadgets doing amazing things, whether it be flying electric cars or telepathic eyeglasses. Our society is obsessed with the Jetsons and the look of the future. That’s why we’re developing so many devices to help us get there. But it’s time for IT to reconsider how they are using one of them for a purpose far from the original idea.

Speaking For The People

By all accounts, the Amazon Echo is a masterful device. It’s a smart speaker that connects to an Amazon service that offers you a wider variety of software programs, called skills, to enhance what you can do with it. I have several of these devices that were either given out as conference attendance gifts or obtained from other giveaways.

I find the Echo speaker a fascinating thing. It’s a good speaker. It can play music through my phone or other Bluetooth-connected devices. But, I don’t really use it for that purpose. Instead, I use the skills to do all kinds of other things. I play Jeopardy! frequently. I listen to news briefings and NPR on a regular basis. I get weather forecasts. My son uses Continue reading

Cisco CEO: “We are still only on the front end” of a new version of the network

Fresh off a positive earnings call that saw Cisco report $11.9 billion in revenue for the 2Q 2018 – a 3 percent increase from the same quarter in 2017 and the first time in 6 quarters the company reported year-over-year sales increases – CEO Chuck Robbins has a lot to crow about.  First of all, the company's most strategic new direction: The Network.

[Video] Configure Data Center Devices with PowerShell

PowerShell started as a tool to automate Windows servers. It was picked up by VMware (and others) as a platform on which they built their own solutions (PowerCLI and PowerNSX)… but did you know you can use it to configure data center infrastructure, including NX-OS switches, SAN networks, and Cisco UCS?

In the Configuring Data Center Devices with PowerShell video, Mitja Robas described how to do that, and provided source code for all his examples.
