Packet loss with Fast Reroute

Packet loss with Fast Reroute Do we still lose packet with fast reroute? One of my students asked me this question. And I would like to share the answer with everyone. Before we discuss whether or not we lose packet with fast reroute mechanisms, let’s remember what fast reroute is. It is pertinent to know […]

BrandPost: How to Beat the Wired Network Bottleneck and Wring More Business Value from your WLAN

If you’re looking at deploying 802.11ac Wi-Fi access point (AP) technology, as most companies have already, you may want to consider upgrading the speed of your wired connection between your APs and your wiring-closet Ethernet switch to avoid the kind of network saturation that puts a damper on worker productivity.  The 802.11ac Wi-Fi standard now accounts for 67.1% of dependent wireless AP shipments and more than 80% of revenue, “setting the stage for near obsolescence of the 802.11n standard by 2018 in the mainstream enterprise segment,” according to the research firm IDC.To read this article in full or to leave a comment, please click here

Microsoft employees say monitoring disturbing content traumatized them

There is a very dark underbelly to the web that is not for the weak of stomach. You may be thinking of 4chan, but that place is just the starting point. Unfortunately, it falls to some people to monitor this garbage for law enforcement, and in the case of two Microsoft employees, it drove them over the edge. In a lawsuit filed against Microsoft, Henry Soto and Greg Blauert claim they were forced daily for months to view some of the most disturbing photos and videos you can find on the internet and that Microsoft did nothing as the constant viewing took its toll on them. They now claim to suffer Post-Traumatic Stress Disorder (PTSD). The two were part of Microsoft’s Online Safety Team, a group formed to investigate content being stored on Microsoft sites, like OneDrive, that should be taken down or reported to police. To read this article in full or to leave a comment, please click here

Google Cloud Key Management Service could help more enterprises encrypt data

Attackers are increasingly able to penetrate perimeter defenses, compromise accounts and mine data without targets even being aware of the attack, as the Democratic National Committee breach proved. Encrypting data is the best defense.Strong encryption of complex data structures requires a Key Management System (KMS). But implementing a KMS can be challenging, especially for enterprises below the security poverty line that don’t have the budget to hire a multidisciplinary security team. Google may have a solution with its Cloud Key Management Service (CKMS) now in beta in select countries.  To read this article in full or to leave a comment, please click here

Worth Reading: Tier 1 carrier performance report

As Noction continues to intelligently optimize routing for more and more networks around the world, we find ourselves in the unique position of having great insights into the general Internet performance as well as the performance of specific Internet carriers, when analyzing data collected by IRP Lite instances. Around 200 million successful probes performed by IRP instances over the previous weeks offered us plenty of data for analysis. The current report card covers the performance of major providers within the continental United States. —Noction

IDG Contributor Network: Infrastructure monitoring: Turn data into knowledge and minimize slowdowns

It’s 2 a.m., and a hospital’s system has slowed to a crawl. Lives are at stake. For the harried system admins looking for the source of the slowdown, time is of the essence.The hospital’s system has servers attached through a SAN to storage devices. But where’s the weak link? The administrator cannot afford to waste time analyzing server performance when the problem may be in a storage device or the SAN. He needs information that enables him to conduct his root cause analysis as quickly as possible.Perhaps you don’t have to worry about whether someone will live or die when your IT infrastructure fails. However, when it’s slow or down, it fails to deliver a satisfying user experience. Also, it’s likely that your company’s operations falter, costs increase, and your bottom line suffers.To read this article in full or to leave a comment, please click here

Is this the year IoT standards will finally make sense?

A few brave souls predict IoT standards will start to gel this year, but making all those connected things work together still looks like a long shot.Two years ago, some industry analysts cautiously suggested that a vast array of IoT standards would merge into just a few beginning in 2017. If the internet of things in late 2014 was a cacophony of discordant musicians tuning up, it’s now reached the point where a few virtuosos are playing the same tune. But there’s still a lot of sheet music getting passed around.To read this article in full or to leave a comment, please click here

The Interplay Of HPC Interconnects And CPU Utilization

Choosing the right interconnect for high-performance compute and storage platforms is critical for achieving the highest possible system performance and overall return on investment.

Over time, interconnect technologies have become more sophisticated and include more intelligent capabilities (offload engines), which enable the interconnect to do more than just transferring data. Intelligent interconnect can increase system efficiency; interconnect with offload engines (offload interconnect) dramatically reduces CPU overhead, allowing more CPU cycles to be dedicated to applications and therefore enabling higher application performance and user productivity.

Today, the interconnect technology has become even more critical than ever before, due to a number …
