I Can Has Privacy: A Special Guest Post from LOL Cat

In honor of International Cat Day, the Internet Society is sharing the journal of Internet Hall of Mane recipient, LOL Cat. LOL Cat first achieved fame with her humorous memes written in “kitty pawtois.” A graduate of Stanfur Universekitty, her work has earned her the Purritzer Prize and many other hon-roars.

Cattain’s Log, Day 1
Sunday night patrol. The dusty creature on the wall has not moved for days. This is my vow: I will bide my time and someday I shall pounce.

Day 8
My human taunts me with the shiny red dot.

Day 13
Bathroom remodel. My human has replaced my old litter box with a loud scary one. The flashing lights blind me. I am not feline good about this.

Day 14
When I hop out of this new litter box, a scary rake comes to gather the litter, ruining my sense of order. I shall spread litter around the house to rectify this mess, but first I must hide behind the new contraption.

I see the word “smart.” This must be a clue. I feel that I am onto something. I have no time to lose, and must dash to the room with the Continue reading

Seagate announces new flash drives for hyperscale markets

The Flash Memory Summit is taking place in Santa Clara, California, this week, which means a whole lot of SSD-related announcements headed my way. One already has my attention for the unique features the vendor is bringing to an otherwise dull market.Seagate is expanding the Nytro portfolio of SSD products with emphasis on the enterprise and hyperscale markets and focusing on read-intensive workloads such as big data and artificial intelligence (AI). It has some of the usual areas of emphasis: lower power requirements and capacity that scales from 240GB to 3.8TB.[ Learn what hyperconvergence is and whether you’re ready for hyperconverged storage. | For regularly scheduled insights, sign up for Network World newsletters. ] Also being updated is data protection via Seagate Secure, which prevents data loss during power failure by enabling data inflight to be saved to the NAND flash. The DuraWrite feature increases random write performance by up to 120 percent or provides maximum capacity to the user.To read this article in full, please click here

BrandPost: SDS: Running Storage Like It’s An Application

As data volumes escalate, many organizations are looking for storage efficiencies — and they have found it with software-defined storage (SDS). “For IT organizations undergoing digital transformation, SDS provides a good match for the capabilities needed — flexible IT agility; easier, more intuitive administration driven by the characteristics of autonomous storage management; and lower capital costs due to the use of commodity and off-the-shelf hardware,” said Eric Burgener, research director at IDC. The analyst firm predicts the SDS market will grow at a compound annual growth rate of 13.5% through 2021.To read this article in full, please click here

Another Benefit of Open-Source Networking Software

You probably know my opinion on nerd knobs and the resulting complexity, but sometimes you desperately need something to get the job done.

In traditional vendor-driven networking world, you might be able to persuade your vendor to implement the knob (you think) you need in 3 years by making it a mandatory requirement for a $10M purchase order. In open-source world you implement the knob, write the unit tests, and submit a pull request.

MikroTik ISP Design: Building an 802.1q trunk between sites using VPLS and S-tag

Use Case

ISPs that use MikroTik are always looking for new ways to deliver services to customers and expand their offerings. Delivering Layer 2 at scale for customers is a design challenge that comes up frequently.

While it’s easy enough to build a VLAN nested inside of another VLAN  (see below), this requires you to build all of the VLANs a customer wants to use into the PE router or handoff switch.

However, if you have a client that needs a layer 2 service delivered to two or more points and wants to be able to treat it just like an 802.1q trunk and add VLANs in an ad-hoc way, then using the S-Tag feature in RouterOS along with VPLS transport is a great option.

What’s the S-tag do???

Clients will often ask me “what’s the S-Tag check box for?”

So a little background on this, there is a protocol for using outer and inner VLAN tags specified in IEEE 802.1ad that uses Service Tag (or S-Tag) to denote the outer VLAN tag used to transport Customer Tags (or C-Tags).

What makes the S-Tag/C-Tag a little bit different is that it actually changes the ethertype of the Frame.

IDG Contributor Network: I’ve got the RF power

If you’re reading this, you’ve got RF power. Power is a necessity for networking, allowing us to charge our batteries, connect millions of devices, communicate over long distances and keep our signals clear.Don’t believe me? Kill the power and see what happens to your network.But with great RF power comes great responsibility. Power management is the art and science of optimizing input and output signals to maximize the efficiency and performance of RF devices – and it’s no easy feat. Each networking device has its own unique power requirements. Higher data rates often mean more power consumption and complexity, which can introduce losses that reduce reliability and increase cost. Low data rate devices, such as those supporting the Internet of Things (IoT), draw very little power in order to conserve every millisecond of precious battery power.To read this article in full, please click here

BrandPost: DNS: Hiding in Plain Sight – It’s No Longer Just Infrastructure. It’s a Requirement for Security, Scalability

During its 35-year history, DNS has been largely known as the backbone of the internet, a powerful tool that enabled the internet’s infrastructure to develop into the distributed marvel it is. Even though it’s always been there, the way it is being used has changed. Now, a modern DNS deployment is also critical to a cybersecurity strategy and to deliver the scalability that growing enterprises need.Once considered solely the internet’s address book, DNS has become a favored target of cybercriminals and hackers who are constantly trying to either cause havoc to or extract valuable data (or cash) from unwitting enterprises worldwide. Because it’s at the center of everything, it’s no great surprise that 90 percent of all cyberattacks, such as DDoS attacks, ransomware, and data exfiltration, target DNS.To read this article in full, please click here
