100G & 25G Plugfests: What we learned

Howdy.

Happy Chinese New Year Y’all!!!

I wanted to take the time and talk about the 25/100G trend we find ourselves in. With more and more platforms being added (Cumulus Linux supports 9 of these platforms with the 3.2 release and we have plans to add more over the next few months), and more customers making the switch to 25/100G as a way to future-proof their networks given the economics of 25/100G open networking switches being on par with their 10/40G counterparts, it’s clear that the 25/100G trend is picking up speed. It was a long journey to get to this point, and we learned a lot on the way. I’d like to take this opportunity to take a look back, analyze the situation and highlight a few things we learned as an industry.

Setting the stage: A short history of the 25G and 100G rush

I don’t know if y’all remember the 100G race between vendors in 2015 to deliver the first 100G switch based on the new 28 GHz standard; everyone had to be first in the market. We even had a handful of 100G switch submissions to OCP by mid 2015. Plus, for the first time Continue reading

Microsoft asks Trump administration for travel ban exceptions

Microsoft today asked the U.S. government to create a mechanism for granting exemptions to last week's executive order on immigration that would meet "the pressing needs of real people," including scores of company employees and their families.In the letter to the heads of the Department of State and Department of Homeland Security, Brad Smith, Microsoft's chief legal officer, asked for exemptions that would apply to people with non-immigrant work visas, student visas or family members. The exceptions would let them come to and go from the U.S. for business trips and family emergencies, those trips not to exceed two weeks.To read this article in full or to leave a comment, please click here

IDG Contributor Network: SSL or IPsec: Which is best for IoT network security?

Internet of Things (IoT) devices are soon expected to outnumber end-user devices by as much as four to one. These applications can be found everywhere—from manufacturing floors and building management to video surveillance and lighting systems.However, security threats pose serious obstacles to IoT adoption in enterprises or even home environments for sensitive applications such as remote healthcare monitoring. IoT security can be divided into the following three distinct components: Application service End device Transport Although all three are critical for systemwide security, this post will address only transport security.To read this article in full or to leave a comment, please click here

RSA 2017: Anticipating network security chatter

Earlier this week, I  wrote about my expectations for endpoint security at the upcoming RSA Conference. Similarly, here’s what I anticipate hearing about regarding network security:1. DDoS protection. While data breaches get front page, above-the-fold headlines, DDoS attacks remain relatively invisible by comparison. This is puzzling because DDoS attacks happen almost daily. A quick review of the news shows that the Trump hotel website, Sonic (ISP in CA), Emsisoft and Lloyd’s Bank have all been hit with DDoS attacks over the past few weeks. These are relatively pedestrian attacks compared to the now infamous Mirai botnet DDoS attack on Dyn back in October and the subsequent attack on French hosting provider OVH a week later. To read this article in full or to leave a comment, please click here

Worth Reading: Automation and ethics

As technologists, we have to mix together two concerns: relentlessly automating all aspects of business and life, while at the same time resisting the urge to become job-destroying, and, thus life-destroying jerks. “I was just doing my job” will be poor solace when we’re all licking the slime out of empty dog food cans. In the same way that we expect oil, chemical, and soda companies to manage the negative effects of their profits, we need to keep a closer eye on the negative effects of automation and, more broadly, IT innovation. —The New Stack

IDG Contributor Network: Beware of the legacy public cloud

Legacy is a scary and bad word in the computing industry. Most enterprises have "legacy" technologies, and all who do wish that they did not.Now everyone thinks of public clouds as the next greatest thing, which means they cannot possibly be "legacy." While the major public cloud vendors (Amazon, Microsoft, Google) currently drive a great deal of innovation, they might also be trapping themselves and their customers into legacy situations.So, there is a real risk that the current public cloud leaders (Amazon Web Services, Microsoft Azure and Google Cloud Platform) could become legacy vendors. To understand this risk, we need to understand what creates legacy technologies and vendors and analyze the strategies of the public cloud vendors.To read this article in full or to leave a comment, please click here

What’s next for Azure Site Recovery?

When Microsoft first showed off its disaster recovery service on Azure in 2014, it was called Hyper-V Recovery Manager and was an extension of a System Center tool for failing over Hyper-V virtual machines (VM) to another location, using the public cloud to coordinate testing and managing recovery between your data centers.To read this article in full or to leave a comment, please click here(Insider Story)

Microsoft wants OEMs to build these kinds of PCs

Microsoft held the Windows Hardware Engineering Conference (WinHEC) in China last December, but it has just released a very interesting video that highlights where it would like to see the PC market head in the coming years. The video, from the session "Next Generation of Windows Devices," isn't all that surprising, as Microsoft has already been advocating for things such as Ink and Hello. Its description of the Modern PC falls into three categories: Cool Designs, Better Performance and New Experiences. + Also on Network World: Battle lines drawn as Chromebooks, Windows PCs renew rivalry + Microsoft had an interesting factoid. It said that there are over 600 million Windows devices in use that are more than 4 years old. Those are pretty much all Windows 7 and perhaps Windows 8 machines, since Windows 10 is only a year old. That's 600 million people Microsoft wants to upgrade. To read this article in full or to leave a comment, please click here

Internet Hall of Fame making a comeback in 2017

The Internet Hall of Fame, a virtual museum celebrating the living history of the Internet, is back seeking a new class of inductees after going quiet for the past couple of years.A spokeswoman for the Internet Society, which fights the good fight for an open and secure Internet, says "we wanted to take some time to get the inductees more involved in the program and get their insights to make sure it was positioned and well-structured for the long-term. We now have an Advisory Board of inductees who provide leadership on the program’s direction and are responsible for the selection of the next class of inductees. With 2017 as the Internet Society’s 25th anniversary, we felt it was the ideal time to host the next induction ceremony."To read this article in full or to leave a comment, please click here

Cisco goes public with Clock Signal Component Issue

A couple months ago many engineers started hearing rumors regarding an ISR 4331 recall, and problems surrounding the device. Until this week, none of us had very good information, but it seems that today Cisco has officially released some information regarding the problem. Many of us have received phone calls at this time from our account managers… while some of us, myself included, have been left in the dark. This is troubling considering how many products are out in the field.

Recently, Cisco became aware of an issue related to a component manufactured by one supplier that affects some Cisco products. In some units, we have seen the clock signal component degrade over time. Although the Cisco products with this component are currently performing normally, we expect product failures to increase over the years, beginning after the unit has been in operation for approximately 18 months. Once the component has failed, the system will stop functioning, will not boot, and is not recoverable.



Cisco has identified the products that are affected by this issue and published an FAQ along with the Field Notices on their site. The list of products varies across the line and includes the following products that Continue reading
