BGP in the data center: Are you leveraging everything BGP has to offer? Probably not. This practical report peels away the mystique of BGP to reveal an elegant and mature, simple yet sophisticated protocol. Author Dinesh Dutt, Chief Scientist at Cumulus Networks, covers BGP operations as well as enhancements that greatly simplify its use so that practitioners can refer to this report as an operational manual.

Magic Quadrant report:  Cumulus Networks has been named a “Visionary” in the Data Center Networking category for 2017 Gartner Magic Quadrant. With 96% of their survey respondents finding open networking to be a relevant buying criterion and with the adoption of white-box switching to reach 22% by 2020, it’s clear that disaggregation is the answer for forward-looking companies.

Worth Reading: Converge your network with priority flow control

Back in April, we talked about a feature called Explicit Congestion Notification (ECN). We discussed how ECN is an end-to-end method used to converge networks and save money. Priority flow control (PFC) is a different way to accomplish the same goal. Since PFC supports lossless or near lossless Ethernet, you can run applications, like RDMA, over Converged Ethernet (RoCE or RoCEv2) over your current data center infrastructure. Since RoCE runs directly over Ethernet, a different method than ECN must be used to control congestion. In this post, we’ll concentrate on the Layer 2 solution for RoCE — PFC, and how it can help you optimize your network. —Cumulus

What is IoT?

The Internet of Things, at its simplest level, is smart devices - from refrigerators that warn you when you’re out of milk to industrial sensors – that are connected to the Internet so they can share data, but IoT is far from a simple challenge for IT departments.For many companies, it represents a vast influx of new devices, many of which are difficult to secure and manage. It’s comparable to the advent of BYOD, except the new gizmos are potentially more difficult to secure, aren’t all running one of three or four basic operating systems, and there are already more of them.A lot more, in fact – IDC research says that there are around 13 billion connected devices in use worldwide already, and that that number could expand to 30 billion within the next three years. (There were less than 4 billion smartphone subscriptions active around the world in Ericsson’s most recent Mobility Report.) To read this article in full or to leave a comment, please click here

The System Bottleneck Shifts To PCI-Express

No matter what, system architects are always going to have to contend with one – and possibly more – bottlenecks when they design the machines that store and crunch the data that makes the world go around. These days, there is plenty of compute at their disposal, a reasonable amount of main memory to hang off of it, and both Ethernet and InfiniBand are on the cusp of 200 Gb/sec of performance and not too far away from 400 Gb/sec and even higher bandwidths.

Now, it looks like the peripheral bus based on the PCI-Express protocol is becoming the bottleneck, …

IDG Contributor Network: How to plan your successful cloud migration

Recent Accenture Strategy research found that four out of five companies run up to half of their business functions in the cloud. Moreover, that figure is likely to increase significantly over the next few years. The research reveals that a clear majority of business leaders see the cloud platform as a critical enabler of greater innovation and competitive edge.Yet, companies still struggle when it comes to structuring the cloud transformation, beginning with the fundamental first step — planning a successful migration. What’s lacking is a solid comprehension of what value the cloud brings, its potential and its elasticity.To read this article in full or to leave a comment, please click here

Worth Reading: Implementing security as a set of services

In this post, I will focus on the implementation of the security services in terms of an ITIL-type framework. This is a blog post that took a long time to write — but some of the considerations here are essential if you are in the process of implementing security as a service, and especially if you are looking at ITIL as a service delivery methodology. —APNIC

Technology Requirements for Deep and Machine Learning

Having been at the forefront of machine learning since the 1980s when I was a staff scientist in the Theoretical Division at Los Alamos performing basic research on machine learning (and later applying it in many areas including co-founding a machine-learning  based drug discovery company), I was lucky enough to participate in the creation and subsequently to observe first-hand the process by which the field of machine-learning grew to become a ‘bandwagon’ that eventually imploded due to misconceptions about the technology and what it could accomplish.

Fueled by across-the-board technology advances including algorithmic developments, machine learning has again become a …

Mythbusting the CCIE Continuing Education Program

It’s been about a month since the CCIE Continuing Education program was announced ahead of Cisco Live. There was a fair amount of discussion about it both on this blog as well as other places, like Jeff Fry’s post. Overall, the response has been positive. However, there are a few questions and ideas about the program that are simply not true. And no, this is not The Death Of The CCIE Program (just Google it). So, let’s take a look at this edition of Mythbusters for the CCIE CE program.

Myth #1: The CE Program Is Just A Way For Cisco To Sell More Training

This was a good one. The list of CE classes that was release at the beginning of the program included Cisco Live classes as well as Cisco Authorized training classes. Those were the only thing on the list as of right now. When some people saw the list, they jumped to the conclusion that the reason why the CE program exists is because Cisco wants to push their training courses. Let’s look at that.

Let’s say you want to start a global program that requires people to keep track of their training credits to turn Continue reading
