Huawei jumps into intent-based networks

The concept of intent-based networks (IBN) has been around for the better part of half a decade, but it’s really only come into its down in the past couple of years. The vision of a “self-driving” network had appeal but was largely science fiction.However, over the past couple of years, we have seen this vision turn into reality with several networking vendors coming to market with products that work. Many of the use cases are still fairly basic, but the foundation has now been laid and intent is where the new battleground for networking vendors will be fought.To read this article in full, please click here

IDG Contributor Network: Cloud vs. data center: How to know what’s right for your organization

It wasn’t that long ago that Amazon CTO Werner Vogels routinely said that any strategy that included on-premises data centers and the public cloud was really just a path to public cloud. Yet today, AWS touts architectures that include both.Microsoft has gone a step further with Azure Stack so that the public cloud vs. data center experience is as seamless as possible for its customers. Google, meanwhile, continues to invest in technologies that admit that some services will stay in private data centers (but you might as well make nice APIs for them, while also making it easier for on-premises business logic to consume public cloud services).To read this article in full, please click here

A Reference Architecture for NVMe over Fabrics

Cavium has raised its profile over the past several years as one of the pioneers in developing Arm-based systems-on-a-chip (SoCs) for servers, rolling out multiple generations of its ThunderX chips in hope of pushing Arm’s low-power architecture make gains in a datacenter environment that for years has been dominated by Intel and its x86-based Xeons.

However, like similar chip makers, Cavium didn’t start with the Arm server chips, but instead built to that point atop a broad array of products for other areas of the datacenter, including adapters, controllers, switches and MIPS-based processors for networking and storage devices. …

A Reference Architecture for NVMe over Fabrics was written by Jeffrey Burt at The Next Platform.

IBM’s Watson, known for AI, takes on IoT

IBM’s Watson has earned fame besting Jeopardy! champions. But now the artificial intelligence (AI) platform is rolling out Watson Assistant, designed to “help bridge the information and data sharing gap between people and things.”Announced this morning at the IBM THINK 2018 conference in Las Vegas, an IBM spokesperson described Watson Assistant in an email as “an AI assistant for enterprises that can be accessed via voice or text interaction. Watson Assistant is helping businesses transform their customer experiences by bringing together data on all the places and things consumers interact with daily.” Watson Assistant is designed to be embedded in a wide variety of things, from cars to conference rooms, retail stores to banks.To read this article in full, please click here

Reviewing logins on Linux

The last command provides an easy way to review recent logins on a Linux system. It also has some useful options –- such as looking for logins for one particular user or looking for logins in an older wtmp file.The last command with no arguments will easily show you all recent logins. It pulls the information from the current wtmp (/var/log/wtmp) file and shows the logins in reverse sequential order (newest first).$ last shs pts/1 192.168.0.15 Mon Mar 19 17:48 still logged in shs tty2 /dev/tty2 Mon Mar 19 17:37 still logged in shs pts/2 192.168.0.15 Mon Mar 19 17:22 - 17:23 (00:00) jdoe pts/3 192.168.0.15 Mon Mar 19 16:51 - 17:22 (00:31) To look for logins for just one particular user, supply their username as an argument.To read this article in full, please click here

Chapterthon Wins 2018 WSIS Prize for International and Regional Cooperation

We are proud to announce that Chapterthon 2017 on Digital Schools was recognized today as the winner of a 2018 World Summit on the Information Society (WSIS) Prize under the category “International and Regional Cooperation,” awarded by the International Telecommunication Union (ITU).

For the Internet Society, this award is a strong affirmation of the valuable work that our Chapters are doing on the ground to empowering their communities through the Internet and, as so, advancing sustainable development.

Chapterthon is a global Chapters marathon, where our chapters work hard with their communities to develop a project within a timeline and budget for achieving a common goal. In 2017, the topic was Digital Schools and 30 Chapters from all 6 regions carried out specific projects to improving education by using the Internet.

Great ideas were taken into action and each project contributes to making a difference not only in their communities but also beyond them. Connecting schools to the Internet through community networks, teaching coding to girls, training teachers and parents, raising awareness about the safe use of the Internet and developing an online platform for a school were not isolated actions but part of global efforts towards improving people’s lives.

Future Thinking: Wired Editor in Chief Nicholas Thompson on the Role of Media

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. Last month we interviewed Nicholas Thompson, Editor in Chief of Wired, to hear his perspective on the forces shaping the Internet’s future.

Prior to joining Wired, Thompson was a journalist at The New Yorker, where he was also the editor of newyorker.com. Thompson has written about politics and technology for numerous publications, and  has spent time reporting from West Africa on the role technology plays there. He is also the author of The Hawk and the Dove: Paul Nitze, George Kennan, and the History of the Cold War.

The Internet Society: You recently published (and co-wrote) a long feature on Facebook’s difficulties over the past two years, focusing to a large extent on its role in distributing news and misinformation (or fake news) alike. As policy leaders shape future norms in this field, do you think platforms face stricter regulatory measures? How? 

Nicholas Thompson: Platforms need to do better. They need to play a better role in Continue reading

IETF 101, Day 3: TLS & DPRIVE is no Diet Coke

This week is IETF 101 in London, and we’re bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. There’s plenty of variety on Wednesday, following the themes of Trust and Identity, IPv6 and the Internet-of-Things.

TLS has its second session of the week starting at 09.30 GMT/UTC, and will be focused on the big development of the TLS 1.3 specification being approved by the IESG. Some further work is required, but there are a number of TLS 1.3 related drafts up for discussion.

These include Datagram Transport Layer Security, DTLS Connection Identifer,  Exported authenticators in TLS, DANE Record and DNSSEC Authentication Chain Extension for TLS, TLS Certificate compression, SNI Encryption in Tunnelling via TLS, and Semi-static DH Key Establishment in TLS 1.3.

NOTE: If you are unable to attend IETF 101 in person, there are multiple ways to participate remotely.

Running in parallel is LPWAN which is working on enabling IPv6 connectivity with very low wireless transmission rates between battery-powered devices spread across multiple kilometres. There’s a draft providing an overview of the set of LPWAN technologies under consideration by the IETF Continue reading

Cloudflare Global Network Spans 137 Cities: Launching Durban and Port Louis Data Centers

Our newest data centers in Durban (South Africa) and Port Louis (Mauritius) expand the Cloudflare network to 137 cities globally. We are delighted to reach this special milestone, and even more excited to help improve the performance and security of over 7 million Internet properties (and growing!) across 69 countries.

Just in March, so far, we've launched new data centers across Beirut, Phnom Penh, Kathmandu, Istanbul, Reykjavík, Riyadh, Macau, Baghdad, Houston, Indianapolis, Montgomery, Pittsburgh, Sacramento, Mexico City and Tel Aviv!

Growing Africa network

Just three years (and about 100 cities ago!), we launched our very first Africa deployment in Johannesburg (South Africa). It was an exciting day for members of our team to facilitate an especially substantial latency improvement for our customers.

Since then, we’ve turned up additional deployments in Cairo (Egypt), Cape Town (South Africa), Djibouti (Djibouti), Luanda (Angola), and Mombasa (Kenya).

Durban is our third deployment in South Africa, where mobile adoption continues to drive traffic growth amongst 20 million Internet users. Other countries with three (or more) Cloudflare data centers are Australia, Canada, China, Germany and United States (with two European states joining this list very Continue reading

Security for Public Clouds (AWS) with vRealize Network Insight

Enterprise IT needs visibility into the network and security status of their workloads, whether hosted on premises, or within AWS. While many AWS workloads are sandboxes for application development teams (DevOps), it is important to analyze these workloads. Increasingly, public cloud workloads are also fulfilling mission-critical production needs for many organizations. Enterprise IT must be ready to determine the best location, security posture, and bandwidth allocation when deploying workloads. Having traffic pattern details as well as security analysis and recommendations readily available, helps organizations make the ideal hosting decisions to meet their business needs.

vRealize Network Insight (vRNI) Supports Amazon Web Services (AWS) Public Cloud. The vRNI traffic monitoring features provide visibility into native AWS constructs such as Virtual Private Clouds, VMs, Security Groups, firewall rules, and tags. vRNI also analyzes AWS traffic flows to provide security and micro-segmentation views of cloud workloads. This means you’ll be able to plan micro-segmentation and understand traffic patterns using data collected from your AWS instances.

 

Let’s review a simple Amazon Web Services (AWS) VPC setup to articulate the value vRealize Network Insight can offer from a Day 1 Day 2 perspective.

  1. We have an on-premise instance of vRealize Network Insight managing AWS.
  2. Continue reading
