IDG Contributor Network: Why your company can be sued for using SD-WAN

When you buy your SD-WAN, or for that matter any WAN technology, you sort of assume that the vendor has the legal right to sell it to you.But what happens if they don’t? What happens if you’ve built your WAN on an illegally acquired technology?The question is not just theoretical. Last week, FatPipe sent me a press release pointing out how United States PTO Patent Court upheld a signature claim to its U.S. patent (number 6,775,235) for load balancing across disparate networks. Load balancing is a critical component of all SD-WAN products. As such, FatPipe could, in theory, claim licensing fees from SD-WAN players and their users.To read this article in full or to leave a comment, please click here

Cumulus Linux + Voyager — Bringing cost-effective scalability to internet infrastructure

We’re thrilled to announce that Facebook has partnered with Cumulus Networks to bring you the industry’s first open optical routing platform loaded with Cumulus Linux. That’s right, Cumulus Networks is branching into some exciting new territory (a new voyage… if you will). We couldn’t be more honored and excited to work closely with Facebook to bring scalability and cost-effective hardware and software to the optical space — an industry that is growing rapidly.

Bandwidth for Internet services is becoming a more tangible challenge every single day, but the current proprietary solutions are too expensive and do not scale. As Facebook explained, “the highest-performing ‘bandwidth and reach’ are still fiber-based technologies — in particular, switching, routing, and transport DWDM technologies.” With the popularity of services that require a lot of bandwidth, like VR and video, there has become a critical need for better backhaul infrastructure that is cost-effective and scalable and supports high-performing wireless connectivity. The issue becomes even more critical when considering a variety of geographic conditions. For instance, rural regions need long backhaul pipes, which is cost-prohibitive.

That’s where Voyager comes in. Voyager was designed to bring the Internet to everyone — from dense urban locations to remote Continue reading

Worth Reading: The ROCA Encryption Vulnerability

Yes. It’s serious in practice and in principle. Infineon used a flawed key generation routine, which means those keys are easier to crack, and the routine is used in chips embedded in a wide variety of devices. It’s reckoned that the flawed routine has been in use since 2012 and has probably been used to generate tens of millions of keys. Naturally, many of those keys will have been generated precisely because someone had data or resources that they particularly wanted to secure. –Robin Wilton @ The Internet Society

IDG Contributor Network: How to use the IoT for continuous business improvement

Few things are drawing as much attention in today’s markets and society alike as the Internet of Things. Almost entirely unknown to the public but a few years ago, today’s IoT is continuously reshaping our lives, changing how we communicate, do business, and share our ideas. Given that few businesses seem to know where to begin when it comes to leveraging the IoT for continuous improvements to their commercial models, then, what steps should managers be taking today to improve their future?A quick review of the IoT’s positive impact on business efficacy shows just how vital it is for corporate CEOs and small business owners alike to get moving immediately when it comes to IoT investment. It’s a brave new interconnected world out there, and those who don’t learn how to manipulate the IoT for their own success will quickly find themselves left in the dust.To read this article in full or to leave a comment, please click here

How SAP is making the shift to industrial IoT

The view of the industrial Internet of Things (IoT) as billions of sensors connected into intelligent systems distracts from its true role: digital transformation. The gargantuan task and investment of making all these connections, reliably and securely, is pointless unless there is a solid business reason — and there are two very good ones.2 reasons manufacturers invest in IoT The first reason big companies invest in IoT is they are worried about being digitally disrupted by a Tesla, Uber, or the next AirBnb in their industries — disrupt or be disrupted.The second reason: a company’s slowing growth and the need for increased productivity. BCG’s Olivier Scalabre explained that driver during a 2016 Ted talk.To read this article in full or to leave a comment, please click here

Introduction to TACACS and TACACS+ (Terminal Access Controller Access Control System)

Today I am going to talk about the TACACS and TACACS+ basics with you. I am sure most of you already knew TACACS and TACACS+ as many of you worked and configured the configuration on your devices whether it will Cisco, Juniper or any other vendor in your network.

Here in this article I am Just talk about TACACS and TACACS+ as follow.

What is TACACS and TACACS+ ?

Well all of you already listern this term so many times but many of you confuse what is TACACS and TACACS+.

Terminal Access Controller Access Control System or called as TACACS is a authentication protocol and is commonly used within the UNIX based networks that allows a remote access server to forward a user's logon password to an authentication server to determine whether access can be allowed to a given system.

TACACS and TACACS+

TACACS is a simple UDP-based access control protocol originally developed by BBN for MILNET. TACACS+ is an enhancement to TACACS and uses TCP to ensure reliable delivery.

DMVPN or Firewall-Based VPNs?

One of my readers sent me this question:

I'm having an internal debate whether to use firewall-based VPNs or DMVPN to connect several sites if our MPLS connection goes down. How would you handle it? Do you have specific courses answering this question?

As always, the correct answer is it depends, in this case on:
