OSPF Prefix Suppression helps company to use 200 routers

OSPF Prefix Suppression helps to company to use 200 routers in their network without any problem. You can think that, some companies use more than 200 routers in their OSPF network, why this post is special? You will understand why in 10 minutes.   Yes that is true but those companies have either multi-area OSPF […]

Information on the Recent Site Migration

Earlier this week, I completed the migration of this site to an entirely new platform, marking the third or fourth platform migration for this site in its 12-year history. Prior to the migration, the site was generated using Jekyll and GitHub Pages following a previous migration in late 2014. Prior to that, I ran WordPress for about 9 years. So what is it running now?

The site is now generated using Hugo, an extraordinarily fast static site generator. I switched to Hugo because it offers a couple of key benefits over Jekyll:

1. Site build times are 10x faster (less than 30 seconds with Hugo compared to over 5 minutes with Jekll)—this directly translates into me being able to test changes to the site much more quickly
2. Hugo is a single binary that’s easily installed on Linux or macOS (and Windows too, though I don’t have any Windows systems)

Hugo also gives me more flexibility that I had with Jekyll, such as generating lists of articles by tag or lists of articles by category. Along with those additions—the ability to browse by tag or category—I’ve also removed the pagination (I mean, who’s really going to page through 188 pages of Continue reading

Mingis on Tech: Android vs iOS – Which is more secure?

Apple's iOS has long had the reputation of being more secure than Android, but that may not necessarily be the case. Here's how to evaluate each side's claims about mobile security.

Interview with Daniel Dib

Daniel Dib is setting up a networking career (from a down-to-earth engineer’s perspective) web site, and started populating it with numerous interviews with fellow networking engineers and architects (all of them well worth reading).

Here are my answers to his questions.

Fujitsu Bets On Deep Leaning And HPC Divergence

One of the luckiest coincidences in the past decade has been that the hybrid machines designed for traditional HPC simulation and modeling workloads. which combined the serial processing performance of CPUs and the parallel processing and massive memory bandwidth of GPUs, we also well suited to run machine learning training applications.

If the HPC community had not made the investments in hybrid architectures, the hyperscalers and their massive machine learning operations, which drive just about all aspects of their businesses these days, would not have seen such stellar results. (And had that not happen, many of us would have had …

Intel, Seagate continue push for increased enterprise SSD capacity

The Flash Memory Summit is taking place in the Silicon Valley, and SSD vendors are showing off some impressive new enterprise-scale drives with greater capacity and performance.Seagate showed off some new products in its Nytro line with 3D NAND, raising capacity four-fold, and also showed off a PCI Express-based card with 64TB capacity. Conveniently, the company did not give the price. Seagate Nytro 5000 SSD line The Nytro 5000 product line is an upgrade to Seagate’s existing XM1440 line of SSDs. These drives range in capacity from 400GB to 2TB. All use the M.2 interface. M.2 is a design that’s different from traditional SATA drives. A typical SATA SSD looks like a 2.5-inch hard disk and uses a SATA interface. M.2 is about the size of a stick of gum and plugs into the motherboard. To read this article in full or to leave a comment, please click here

Worth Reading: What we learn in transitioning from card catalogs

When we transition to a new technology, do we lose valuable metadata? Could errors be introduced in the process of transfer of data from one medium to another? It’s an issue society has already had to confront — when the world’s libraries transitioned to digital and online catalogs from their older systems based on paper cards. —David Cassel @ The New Stack

IBM Highlights PowerAI, OpenPower System Scalability

The golden grail of deep learning has two handles. On the one hand, developing and scaling systems that can train ever-growing model sizes is one concern. And on the other side, cutting down inference latencies while preserving accuracy of trained models is another issue.

Being able to do both on the same system represents its own host of challenges, but for one group at IBM Research, focusing on the compute-intensive training element will have a performance and efficiency trickle-down effect that speed the entire deep learning workflow—from training to inference. This work, which is being led at the T.J. Watson …

IDG Contributor Network: Driving operational excellence with your cloud vendors

Once, there was a pin factory. It employed ten workers – each of whom performed a different task. This organizational structure allowed them to generate 48,000 pins every day. If the people working at the plant were working independently, the output of each would have been limited to 20 pins at most – totaling 200 pins. This story describing division of labor was used in Adam Smith’s 1776 book The Wealth of Nations, as an example of operational excellence (OE).If your company is to survive in a competitive market, OE must be sought, explained Faisal Hoque in Fast Company. In other words, the enterprise must “identify, understand and create the capabilities, behaviors and focuses necessary for repeatable, continuous and measurable operational improvement,” said Hoque.To read this article in full or to leave a comment, please click here

On the ‘web: Hyperconvergence in the Network

First there is white box; the networking world is already moving in this direction. While network devices, such as firewalls, routers, and switches were once purchased in an “appliance” model, many parts of the networking world are quickly moving towards a disaggregated model, where the hardware and software are purchased as separate “things.” This enables the concept of white box—although the box might not actually be white. The terms “bright box” and “grey box” attempt to capture the reality that you might still buy boxes from brand named vendors, but rather than buying them for their software capabilities, you can now buy them for their hardware capabilities.

Network slicing will play key role in 5G networks

Single wireless networks will be separated into many, layered virtual networks when 5G is launched, experts say. The technique, called network slicing, is of a similar concept to software-defined networking (SDN), found now in some fixed networking, where managers program network behavior.The way dynamic network slicing will work is that communications specific to a particular 5G application, such as those found in Internet of Things (IoT) sensors or video, will be layered over the top of a common infrastructure, then software will manage the different service types.To read this article in full or to leave a comment, please click here
