Marvell Cranks Up Cores And Clocks With “Triton” ThunderX3
Arm server chip upstart Ampere Computing made a big splash with its 80-core “Quicksilver” Altra processor two weeks ago, and Marvell, which is the volume leader in Arm server chips with its “Vulcan” ThunderX2 processors (largely inherited from its acquisition of Broadcom’s Arm server chip assets), is hitting back with some revelations about its future “Triton” ThunderX3 chip and its roadmap out beyond that. …

DockerCon LIVE with theCUBE: Call for Papers is Open
CFP Deadline: March 27th at 11:59 PM PST
The beauty of Docker is in the ways that developers are using it to positively impact their lives, industries, and day-to-day workflows. From sending rockets to space, to running some of the biggest apps on Earth, Docker helps developers build and share containerized apps – from the boring to the apps that change the world. DockerCon is the place where the community comes together to connect and share stories, best practices, and use cases.
Back in December, we announced that DockerCon would not be a physical event but instead was evolving into a digital event. At the time, that decision was made in order to make attending DockerCon an option for any and all developers and members of the community. And now with the current state of the global COVID-19 pandemic, we are extra thankful to have already been planning for a virtual-only gathering. This change to DockerCon is the safest and healthiest option for our community, and we are excited to still bring everyone together to learn and share from one another.
This year, DockerCon will be a virtual event on May 28th from 9am to 5pm GMT -8. Continue reading

The Week in Internet News: Coronavirus Shutdowns Expose Digital Divide
No Internet, no school: School closings in the U.S. in response to the coronavirus pandemic are exposing the continuing digital divide in the country, U.S. News and World Report says. The Federal Communications Commission should step in to help poor students get access, Commissioner Jessica Rosenworcel told a Senate committee recently.
Testing the Internet’s capacity: Meanwhile, there are some worries that millions of people potentially working from home in the coming weeks could literally “break the Internet,” Slate reports. Corporate VPNs, stock trading sites, and video gaming services could be among the services impacted by people working from home.
Bad news in the U.K.: In Britain, broadband networks aren’t ready for millions of people working from home, ABC14News.com reports. Many home-based Internet services in the U.K. still use old copper-based networks, and Internet users should expect congestion.
The downside of working from home: One Washington Post writer worked from home for eight days and ran into several difficulties, including Internet outages. “Video conferencing fails 50 percent of the time. The online tools I’m using — Slack, Microsoft Office, Dropbox — treat work as paramount, so it never really goes away.”

Announcing Network Analytics
Our Analytics Platform
Back in March 2019, we released Firewall Analytics which provides insights into HTTP security events across all of Cloudflare's protection suite; Firewall rule matches, HTTP DDoS Attacks, Site Security Level which harnesses Cloudflare's threat intelligence, and more. It helps customers tailor their security configurations more effectively. The initial release was for Enterprise customers, however we believe that everyone should have access to powerful tools, not just large enterprises, and so in December 2019 we extended those same enterprise-level analytics to our Business and Pro customers.
Since then, we’ve built on top of our analytics platform; improved the usability, added more functionality and extended it to additional Cloudflare services in the form of Account Analytics, DNS Analytics, Load Balancing Analytics, Monitoring Analytics and more.
Our entire analytics platform harnesses the powerful GraphQL framework which is also available to customers that want to build, export and share their own custom reports and dashboards.
Extending Visibility From L7 To L3
Until recently, all of our dashboards were mostly HTTP-oriented and provided visibility into HTTP attributes such as the user agent, hosts, cached resources, etc. This is valuable to customers that use Cloudflare to protect and accelerate HTTP Continue reading
vlog. Episode 8. History and future of the networking.
Hello my friend,
Today I have a unique opportunity to talk to one of the most well-known authors in the networking industry. Especially if you ever studied for CCIE (link). This is a legendary person, which put his hands on the implementation of many technologies in the service providers, data centres and enterprises.
In this episode, together with Jeff Doyle (yes, this particular Jeff Doyle) we discuss his experience as an author of the networking books, and as a network engineer and architect. We discuss the major steps in the telecommunication’s development over a couple of past decades and what we should expect.
On top of that, Jeff shares his opinion on the skills necessary for the network engineers now and in the future.

Understanding, detecting and localizing partial failures in large system software
Understanding, detecting and localizing partial failures in large system software, Lou et al., NSDI’20
Partial failures (gray failures) occur when some but not all of the functionalities of a system are broken. On the surface everything can appear to be fine, but under the covers things may be going astray.
When a partial failure occurs, it often takes a long time to detect the incident. In contrast, a process suffering a total failure can be quickly identified, restarted, or repaired by existing mechanisms, thus limiting the failure impact.
Because everything can look fine on the surface, traditional failure detectors or watchdogs using external probes or monitoring statistics may not be able to pick up on the problem. Today’s paper choice won the authors a best paper award at NSDI’20. It contains a study of partial failure causes, and a novel approach to fault detection using system-specific, auto-generated watchdogs.
Characterising partial failures
Before designing a better system for detecting partial failures, the authors set about understanding their nature and causes through a study of five software systems (ZooKeeper, Cassandra, HDFS, Apache, and Mesos). For each of these systems they crawled the bug databases to find critical issues Continue reading
