50 Shades of Open Source: How to Determine What’s Suitable for Enterprise White Box Networking

To date, the open source community has been quite successful in terms of coming up with scalable and reliable implementations for enterprise servers, databases and more. Yet many enterprises remain skittish about implementing open source software, probably no more so than in the networking space.

Part of the reason is that there are so many different implementations of open source software, many of them backed by different entities with different agendas. Having many minds contribute to an open source project can be a good thing – until it comes time to make a decision about something and stick with it, so you can get a working product out the door. Enterprises need practical implementations that they can count on day in and day out to get a job done.

Defining the shades of open source
Open source essentially comes in different shades that are not all created equal. Understanding them will help you determine whether the open source implementation you have in mind has the kind of reliability and stability you need in any enterprise IT tool or application.

At a base level is the “pure” open source community, where like-minded people contribute their time and knowledge to a project. Continue reading

What is DHCP, and why might its days may be numbered as IPv6 grows?

Dynamic Host Configuration Protocol (DHCP) is the standard way network administrators assign IP addresses in IPv4 networks, but eventually organizations will have to pick between two protocols created specifically for IPv6 as the use of this newer IP protocol grows.DHCP, which dates back to 1993, is an automated way to assign IPv4 addresses, but when IPv6 was designed, it was provided with an auto-configuration feature dubbed SLAAC that could eventually make DHCP irrelevant. To complicate matters, a new DHCP – DHCPv6 – that performs the same function as SLAAC was independently created for IPv6. [ Now read 20 hot jobs ambitious IT pros should shoot for. ] Deciding between SLAAC and DHCPv6 isn’t something admins will have to do anytime soon, since the uptake of IPv6 has been slow, but it is on the horizon.To read this article in full, please click here

Intel continues to optimize its products around AI

Normally, this is the time of year when Intel would hold its Intel Developer Forum conference, which would be replete with new product announcements. But with the demise of the show last year, the company instead held an all-day event that it live-streamed over the web.The company’s Data Centric Innovation Summit was the backdrop for a series of processor and memory announcements aimed at the data center and artificial intelligence, in particular. Even though Intel is without a leader, it still has considerable momentum. Navin Shenoy, executive vice president and general manager of the Data Center Group, did the heavy lifting.News about Cascade Lake, the rebranded Xeon server chip First is news around the Xeon Scalable processor, the rebranded Xeon server chip. The next-generation chip, codenamed “Cascade Lake,” will feature a memory controller for Intel’s new Intel Optane DC persistent memory and an embedded AI accelerator that the company claims will speed up deep learning inference workloads by eleven-fold compared with current-generation Intel Xeon Scalable processors.To read this article in full, please click here

Improving Gender Rights Online: Perspectives from the Global South

The Internet has helped to empower communities of across the globe. However, existing gender disparities, discrimination, and inequalities, especially faced by women living in the Global South, including the least developed countries, has had a  considerable impact on the digital gender divide, leading to the digital exclusion of women.

A study “Views & Perspectives on Gender Rights Online, for the Global South”, was undertaken by Amrita Choudhury, CCAOI & Asia Pacific lead for the Internet’s Society SIG Women and Nadira AL Araj, ISOC Palestine and MENA Civil Society activist, to identify the main challenges towards improving the gender access and rights online, especially in the Global South; highlight the best practices which nations or regions have adopted to overcome those challenges; and suggest policy areas which need reforms.

In addition to relying on secondary sources, the opinions of 19 experts from 15 countries and responses of 162 people from 54 countries were sought. The findings were further discussed and validated through a workshop at the Internet Governance Forum (IGF) 2017 “Redefining Rights for a Gender Inclusive Connected Future (WS 102) and then compiled into a report.

The top challenges identified across the Global South hampering the creation Continue reading

IDG Contributor Network: Evolution of IT departments to support IoT and digital transformation

You can’t spell IoT without IT, but that doesn’t mean IT departments are big fans of Internet of Things deployments. In fact, we’ve observed that IoT tends to exacerbate some of the challenges that IT departments face within their organizations.Understanding and anticipating IT’s primary areas of concern can help IoT deployments succeed.Lines are blurring Traditionally, the IT department has operated in a vacuum. The focus of IT departments has been in internal support, network management and managing enterprise applications. IoT deployments have been the traditional focus of operations teams that typically deploy point solutions to solve a business issue.To read this article in full, please click here

Updated: First Set of Building Next-Generation Data Centers Self-Study Materials

When I started the Building Next-Generation Data Centers online course, I didn’t have the automated infrastructure to support it, so I had to go with the next best solution: a reasonably-flexible Content Management System, and Mediawiki turned out to be a pretty good option.

In the meantime, we developed a full-blown course support system, included guided self-paced study (available with most ipSpace.net online course), and progress tracking. It was time to migrate the data center material into the same format.

Measuring ECDSA in DNSSEC – A Final Report

Four years ago we started looking at the level of support for ECDSA in DNSSEC. At the time we concluded that ECDSA was just not supported broadly enough to be usable. Four years later, let's see if we can provide an updated answer to the question of the viability of ECDSA.
