Juniper Networks looking to go private?

Juniper Networks has reportedly hired investment banker Goldman Sachs to explore taking the company private.The development has the blessing of activist investor Elliott Management, according to the website Benzinga. Elliott owns 4.5% of Juniper and has encouraged the company to look for ways boost shareholder value through restructurings and product portfolio rationalization.Juniper did reorganize last year at the urging of Elliott after multiple quarters of lackluster performance.To read this article in full or to leave a comment, please click here

Can $1M in damages be accurate in a website defacement?

Corporate security pros should note that journalist Matthew Keys was convicted this week of changing a headline on the LA Times Web site, a case that may help define what can be included when a toting up damages caused by hackers. The bill cited in court came to $929,977 for the cost of changing back the altered headline, which stayed live for less than an hour, but also the cost of assessing what other damage was done and fixing it, which took months. You can read details about the case here and here.To read this article in full or to leave a comment, please click here

Basics: Explaining the Difference Between Software Defined Networking (SDN) and Network Functions Virtualization (NFV)

The next generation of networking is more complex and multi-functional compared to the networks of today. Networks are moving from “connectivity as a service” to “multi- service platform. Takeaways SDN & NFV are complementary technologies NFV depends on SDN to deliver network features that enable it. Both use controller concepts for Operations and Administration (OAM). […]

Forbes: Inside The Crystal Ball:  Five Data Center Trends For 2020 And Beyond
By Michael Levy
Standing at more than one million square feet, the United States Intelligence Community’s Utah Data Center is one of the world’s largest infrastructures. Costing nearly $2 billion, the site boasts storage capacity of almost 12 exabytes. That’s impressive considering the first electronic programmable computer was turned on at the University of Pennsylvania less than 75 years ago. Continue reading

Old-school sexting, as in circa 1969

Sexting among today’s teenagers was the subject of an email string this morning that eventually took a turn down memory lane, courtesy of a long-time friend who wouldn’t make up stuff like this: “Which reminds me of a story from 9th grade (1969 or ‘70). I was outside the high school with a couple of friends one morning before homeroom when we noticed some kind of small piece of paper falling from a second-story window. We went over and picked it up, and it wasn’t a piece of paper after all! Rather, it was a still-developing Polaroid of a kid’s (penis) with the handwritten caption, ‘(Not-to-be-named-here kid’s penis.)’  Technology really has come a long way.”To read this article in full or to leave a comment, please click here

Wi-Fi Alliance reaches for peace over unlicensed LTE

A Wi-Fi Alliance workshop next month could start to lay the groundwork for peace between Wi-Fi and LTE promoters who have been arguing over potential interference.If LTE and Wi-Fi can operate peacefully in unlicensed spectrum, mobile users should be able to get a better experience in in crowded areas whether they are using their carrier's service or a Wi-Fi hotspot.The group will bring together representatives of both sides and lay out proposed guidelines for coexistence between Wi-Fi and LTE on unlicensed frequencies. The workshop, on Nov. 4 in Palo Alto, California, will be the first of several such meetings, the Alliance says.The goal is to have every unlicensed LTE product tested on its ability to coexist with Wi-Fi. Those tests might be administered by the Wi-Fi Alliance or by another body, said Edgar Figueroa, president and CEO of the Alliance. To read this article in full or to leave a comment, please click here

‘Steve Jobs’ review: Unconventional, entertaining, but incomplete

If you know enough about Steve Jobs, watching the new biopic Steve Jobs without bias is almost impossible. You can’t help think about Apple event keynotes, anecdotes from books about the late Apple CEO, the devices you use or have used that were guided by his vision.But try to leave all of that aside and appreciate Steve Jobs for what it is: entertainment. That’s where the movie succeeds, even as facts are fudged.Screenwriter Aaron Sorkin (of The Social Network fame) constructed Steve Jobs around three major product launches: the Macintosh in 1984, the 1988 introduction of NeXT’s computer, and Jobs’s triumphant return to Apple with the iMac in 1998. Those three acts take place over 15 years of personal and professional strife in Jobs’s life, and that limited timeline by nature omits the growth he experienced both as a leader and as a person. This is a movie about Steve Jobs that doesn’t include the launch of the iPhone, what some might consider his greatest achievement, or even a mention of his wife, Laurene Powell Jobs, and their three children together.To read this article in full or to leave a comment, please click here

HP, SanDisk partner to bring storage-class memory to market

Hewlett-Packard and SanDisk today announced an agreement to jointly develop "Storage Class Memory" (SCM) that could replace DRAM and would be 1,000 times faster than NAND flash.The two companies will market their SCM products for use in enterprise cloud infrastructures based on HP's memristor (a revolutionary form of resistor), which it has been developing for at least five years, and SanDisk's ReRAM memory technology.The resulting non-volatile memory technology is expected to be up to 1,000 times faster while offering up to 1,000 times more endurance than flash storage, the companies said.To read this article in full or to leave a comment, please click here

US won’t seek legislation against encryption

The U.S. administration will not seek legislation at this point to counter the encryption of communications by many technology services and product vendors, but will work on a compromise with industry, a senior U.S. official said Thursday. "The administration is not seeking legislation at this time," Federal Bureau of Investigation Director James Comey said in a statement before a Senate Committee on Homeland Security and Governmental Affairs. Comey had previously asked for a "robust debate" on encryption of communications, saying that the technology could come in the way of his doing his job to keep people safe.To read this article in full or to leave a comment, please click here

Single RX queue kernel bypass in Netmap for high packet rate networking

In a previous post we discussed the performance limitations of the Linux kernel network stack. We detailed the available kernel bypass techniques allowing user space programs to receive packets with high throughput. Unfortunately, none of the discussed open source solutions supported our needs. To improve the situation we decided to contribute to the Netmap project. In this blog post we'll describe our proposed changes.

Our needs

At CloudFlare we are constantly dealing with large packet floods. Our network constantly receives a large volume of packets, often coming from many, simultaneous attacks. In fact, it is entirely possible that the server which just served you this blog post is dealing with a many-million packets per second flood right now.

Since the Linux Kernel can't really handle a large volume of packets, we need to work around it. During packet floods we offload selected network flows (belonging to a flood) to a user space application. This application filters the packets at very high speed. Most of the packets are dropped, as they belong to a flood. The small number of "valid" packets are injected back to the kernel and handled in the same way Continue reading
