Comprehensive Internet E-Mail Security
William Stallings

At its most fundamental level, the Internet mail architecture consists of a user world in the form of Message User Agents (MUA), and the transfer world, in the form of the Message Handling Service (MHS), which is composed of Message Transfer Agents (MTA). The MHS accepts a message from one user and delivers it to one or more other users, creating a virtual MUA-to-MUA exchange environment. This architecture involves three types of interoperability.

Cloudy-Eyed: Complexity and Reality with Software-Defined Networks
Russ White and Shawn Zandi

Software-Defined Networks (SDN) are promoted as a way to eliminate the complexity of distributed control planes, increase network responsiveness to specific applications and business requirements, and reduce operational and equipment cost. If this description sounds like the classic “too good to be true” situation, that’s because it might just be.

The Future of Automation

Future-of-Automation-1.jpg

Automation is a hot topic. And the automation concept that has captured our imagination the most is the idea of self-driving cars. This is the kind of automation that we can see dramatically changing what we do everyday, within grasp in our lifetime.

The automotive industry, the press, and parents of 16 year-olds will tell you that the promise of self-driving cars is all about societal benefits: people make mistakes, people don’t always have the best information, and people have to drive with…other people. We can keep everybody safe if everybody just moves to self-driving cars.

But I believe that the benefits of automation are actually much more personal. It’s about getting your life back. Let’s let the computers do the tasks that are mundane and that we shouldn’t be spending time on - like waiting in traffic - so that way we can focus on the things that are important to us.


Ansible: Automation is for people

Automation is intensely personal. It’s not necessarily for the organization, although it it does help. And it’s not just for efficiency’s sake or business sake. At the end of the day, it’s really about helping people.

Automation sometimes gets a bad rap because people think, “Well, if I automate my Continue reading

Worth Reading: Beware of Linking Ads

Privacy advocates are warning federal authorities of a new threat that uses inaudible, high-frequency sounds to surreptitiously track a person’s online behavior across a range of devices, including phones, TVs, tablets, and computers. The ultrasonic pitches are embedded into TV commercials or are played when a user encounters an ad displayed in a computer browser. While the sound can’t be heard by the human ear, nearby tablets and smartphones can detect it. —ARS Technica

Cisco sales tick up, CEO Robbins bullish on data center, security, collaboration

Cisco announced Wednesday that it eked out 1% revenue growth in its fiscal first quarter, compared to the same quarter last year, in what CEO Chuck Robbins described as a “challenging global business environment.” Total revenue for the quarter, which ended October 29, was $12.4 billion. Net income was $2.3 billion, off 4% year over year. Switching, which represents about 30% of the company’s sales, was down 7% in the quarter compared to last year. In an earnings call with financial analysts, CFO Kelly Kramer said the softness was in campus switching, which is two-thirds of the total switching business.CISCO NEWS: Cisco CEO Robbins: Wait til you see what’s in our innovation pipeline | Cisco CEO: Spin-in technologies aren’t dead at Cisco | Cisco/Ericsson: Assessing the mega-deal a year later Asked by analysts if this was a byproduct of macroeconomic trends or a product portfolio issue, Kramer chalked it up to the former, saying the company is confident of its portfolio and expects sales to pick up when spending increases.To read this article in full or to leave a comment, please click here

Review: Almond 3 Wi-Fi router will bring you joy

If you’re a fan of the little guy, one such company to root for is Securifi, which makes a really cool Wi-Fi router known as the Almond. The first version of this router came out in 2012, featuring a touch-screen display long before some other competitors added screens to their routers.The latest version, Almond 3, has entered the wireless mesh arena, offering three Almond routers in a pack to let owners set up a mesh network in their homes as well as new smart home control options (including Amazon Echo integration). The company recently sent me a three-pack and a bunch of sensors to test out.To read this article in full or to leave a comment, please click here

Get to Know the Docker Datacenter Networking Updates

The latest release of Docker Datacenter (DDC) on Docker Engine 1.12 brings many new networking features that were designed with service discovery and high availability in mind. As organizations continue their journey towards modernizing legacy apps and microservices architectures, these new features were created to address modern day infrastructure demands. DDC builds on and extends the built-in orchestration capabilities including declarative services, scheduling, networking and security features of Engine 1.12. In addition to these new features, we published a new Reference Architecture to help guide you in designing and implementing this for your unique application requirements.

Docker Datacenter Worker Node Diagram

Among the new features in DDC are:

  • DNS for service discovery
  • Automatic internal service load balancing
  • Cluster-wide transport-layer (L4) load balancing
  • Cluster-wide application-layer (L7) load balancing using the new HTTP Routing Mesh (HRM) experimental feature

 

When creating a microservice architecture where services are often decoupled and communicated using APIs, there is an intrinsic need for many of these services to know how to communicate with each other. If a new service is created, how will it know where to find the other services it needs to communicate with? As a service needs to be scaled, what mechanism can be used for Continue reading

Cumulus Linux Network Command Line Utility

Here at Cumulus Networks, we believe that network engineers are the real heart of an organization. They’re the ones managing switches, running the data center, and generally keeping an organization moving efficiently and securely.

We also believe web-scale networking and the associated benefits should be accessible to everyone and the best way to make that happen is to leverage the power of disaggregation and native Linux. Although web-scale networking is very flexible, agile and offers many benefits, there can be a learning curve as Linux uses separate, independently developed applications which each have their own syntax to configure the switch.

So how do we bridge these two beliefs? Allow us to introduce Cumulus Linux Network Command Line Utility (NCLU). Scheduled for our early December 3.2 release, NCLU empowers and quickens the learning curve so all network engineers can benefit from web-scale networking while integrating with and still supporting the traditional Linux methods. In short, NCLU makes Cumulus Linux easily accessible to everyone.

What is Cumulus Linux Network Command Line Utility?

NCLU is a command line utility for Cumulus Linux that rides in the Linux user space as seen below. It provides consistent access to networking commands directly via bash, Continue reading

Why your new data center doesn’t work; the sorry state of commissioning

For enterprise IT organizations embarking on a data center capital project, the stakes are undeniably high. Building a new data center is a massive investment, but it also enables or hampers an organization’s IT strategy and capability—affecting an organization’s business performance for years to come. As more organizations rely on colocation data center providers, ensuring the design and construction of these projects meet your business requirements is critical as well.+ Also on Network World: Envisioning a 65-story data center + With multiple vendors, subcontractors and typically more than 50 different disciplines involved in any data center project—structural, electrical, HVAC, plumbing, fuel pumps, networking and more—it would be remarkable if there were no errors introduced or corners cut during the construction process.To read this article in full or to leave a comment, please click here
