Introducing the Internet Intelligence Map

Today, we are proud to announce a new website we’re calling the Internet Intelligence Map. This free site will help to democratize Internet analysis by exposing some of our internal capabilities to the general public in a single tool.

For over a decade, the members of Oracle’s Internet Intelligence team (first born as Renesys, more recently as Dyn Research, and now reborn with David Belson, former author of Akamai’s State of the Internet report) have helped to break some of the biggest stories about the Internet.  From the Internet shutdowns of the Arab Spring to the impacts of the latest submarine cable cut, our continuing mission is to help inform the public by reporting on the technical underpinnings of the Internet and its intersection with, and impact on, geopolitics and e-Commerce.

And since major Internet outages (whether intentional or accidental) will be with us for the foreseeable future, we believe offering a self-serve capability for some of the insights we produce is a great way to move towards a healthier and more accountable Internet.

The website has two sections: Country Statistics and Traffic Shifts.  The Country Statistics section reports any potential Internet disruptions Continue reading

A Partnership to Tackle Growing Risks in a Connected World

With a shared vision of putting people at the center of the Internet, the Internet Society and Consumers International have formed a new working partnership aimed at creating a safer, more trusted Internet for everyone.

As stated in a joint letter to G20 leaders, both organizations share the view that the unwritten future of the Internet is full of endless opportunity, but that if we want everyone to benefit from its potential we need to make sure it is fair, open, safe and secure.

Only by prioritizing the needs of people in an increasingly-connected world, can we make this possible. Consumers should be confident in their use of Internet-connected devices, and have the right to know how their personal data is collected, protected, shared and stored.

Our organizations plan to work together on a wide range of initiatives including to make sure individuals have access to secure Internet-connected devices, understand what online privacy and security means for them, and are empowered to make informed choices about the technology they use in their daily lives.

The Internet of Things (or IoT) offers the promise of convenience, efficiency and more personalized services. It’s a phenomenon that’s being seen all around the Continue reading

BrandPost: Blockchain is Coming for Storage

Although much of the initial excitement for blockchain technology centered around bitcoin and financial services, it’s quickly showing applicability to other areas for increased business value.For example, Walmart has invested in blockchain to improve its supply chain operations. In initial tests, the retailer says the technology reduced the time it takes to track food as it moves from farms to stores — from six days to two seconds.That’s all due to the decentralized nature of blockchain. It’s often referred to as a distributed consensus model, consisting of nodes or blocks of encrypted information. Each node contains the exact same data and transaction history, and that information is secured with cryptographed hashes and digital signatures.To read this article in full, please click here

MANRS BCOP published as RIPE document

The MANRS initiative’s set of Best Current Operational Practices has received recognition from the RIPE community by being published as RIPE-706.

Mutually Agreed Norms for Routing Security (MANRS) – which is supported by the Internet Society – aims to help network operators around the world to improve the security and resilience of the global routing system through four actions that include filtering, anti-spoofing, coordination and support for global validation. It currently involves over 85 organisations encompassing nearly 200 Autonomous Systems around the world, including some of the largest ISPs.

The MANRS BCOP offers guidance on how to practically implement each of the MANRS actions, based on the operational experiences of numerous network operators around the world. It’s a must read for those working with the global routing system, as routing security is a shared responsibility and needs commitment to good practices from all its participants.

The RIPE documents are developed and approved by the RIPE community, having been published since 1989. They include technical and operational recommendations, as well as policy, procedural and organisational documents. The publication of RIPE-706 represents community recognition of the MANRS principles and the importance of a commitment to routing security.

The MANRS initiative would like to thank David Freedman, Brian Continue reading

IDG Contributor Network: Intent-based networking

In campus networking, there are a number of emerging trends impacting the way networks will be modeled in the future. These arising trends include mobility, Internet of Things (IoT), and uniformed security across the wired and wireless connections.To be in tune with these trends, a new era of networking is required that enforces policy-based automation from the edge of the network to public and private clouds using an intent-based paradigm. An example of such would be SD-Access.To read this article in full, please click here

Datanauts 138: What’s Up With Ethernet Fabrics?

Today on the Datanauts podcast, we review the state of Ethernet fabrics in 2018.

Between 2010 and 2012, before SDN became the new marketing hotness, it seemed like vendors were churning out Ethernet fabric products for the data center. Everyone had at least one fabric, and some had two or three.

As time has marched on, many of those Ethernet fabrics have dropped off the map. To catch us up and review what Ethernet fabric means today is Stefan Fouant. Stefan is the Chief Architect at Copper River Technologies, a Juniper Ambassador, a quadruple JNCIE, and author of the book Day One: Junos Fusion Data Center Up and Running.

We look at the status of Ethernet fabric protocols such as TRILL and SPB. We also dig into BGP EVPN, the latest hot fabric.

We also discuss the characteristics of a fabric, look at reasons why a fabric might make sense in your data center, and explore inter-fabric connectivity.

Cisco CEO Chuck Robbins: Get ready for the network’s next act

Cisco’s annual user event, Cisco Live, is being held in Orlando, Florida, this week. While Orlando is home to DisneyWorld, Universal Studios and other places where fantasies come true, the one thing that isn’t make-believe is the turnaround of Cisco since Chuck Robbins took over as CEO. When the baton was passed to Robbins in August of 2015, Cisco’s stock was trading at about $25/share and had been moving sideways for years. Today, it’s trading at about $45/share and at a 17-year high, and the turnaround is well underway.Cisco goes back to the network How did Robbins get Cisco’s mojo’s back in such a short period of time? The answer lies in its roots and a refocus on the network. In fact, when Robbins took over as CEO, I wrote a post outlining some priorities for him as he stepped into the role. My first point was to approach IT through the lens of the network. In the years leading up to the transition to Robbins, I felt Cisco had tried too hard to prove itself as a server and traditional IT vendor instead of staying true to networking.To read this article in full, please click here

What Is Intent-Based Networking?

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

Whenever someone mentions intent-based networking I try to figure out what exactly they’re talking about. Not surprisingly, I get a different answer every single time. Confused by all that, I tried to find a good definition, but all I could find was vendor marketing along the lines of “Intent-based networking captures and translates business intent so that it can be applied across the network,” or industry press articles regurgitating vendor white papers.

Medea: scheduling of long running applications in shared production clusters

Medea: scheduling of long running applications in shared production clusters Garefalakis et al., EuroSys’18

(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site).

We’re sticking with schedulers today, and a really interesting system called Medea which is designed to support the common real world use case of mixed long running applications (LRAs) and shorter duration tasks within the same cluster. The work is grounded in production cluster workloads at Microsoft and is now part of the Apache Hadoop 3.1 release. In the evaluation, when compared to the Kubernetes’ scheduling algorithm Medea reduces median runtimes by up to 32%, and by 2.1x compared to the previous generation YARN scheduler.

…a substantial portion of production clusters today is dedicated to LRAs…. placing LRAs, along with batch jobs, in shared clusters is appealing to reduce cluster operational costs, avoid unnecessary data movement, and enable pipelines involving both classes of applications. Despite these observations, support for LRAs in existing schedulers is rudimentary.

The challenges of scheduling long-running applications

Example uses of long running application containers include streaming systems, interactive data-intensive applications (maintaining Continue reading
