IDG Contributor Network: SD-WANs lost my voice

If there’s one application that brings chills to the hearts of SD-WAN implementers it’s providing a predictable real-time voice service. So let’s talk about how SD-WANs might help.The problem with voice We need to separate from the theory of voice and the reality of voice. The theory goes something like this. The Internet is fine for email and web browsing. It’s even pretty good for personal voice. But if I want to deliver a voice service, day-in-day out without a hiccup, then I run into a problem. Voice is a real-time protocol with strict tolerances around latency, loss and jitter. Exceed those tolerances and symptoms common to a poor voice service set in. Increased delays from traffic routing or lost packets disrupt voice calls. Outages and brownouts can cause calls to drop.To read this article in full or to leave a comment, please click here

Network Slices

There has been a lot of chatter recently in the 5G wireless world about network slices. A draft was recently published in the IETF on network slices—draft-gdmb-netslices-intro-and-ps-02. But what, precisely, is a network slice?

Perhaps it is better to begin with a concept most network engineers already know (and love)—a virtual topology. A virtual topology is a set of links, with some subset of connected devices (either virtual or real), that act as a subset of the network. Isn’t such a subset of the network a “slice” if you look at it from a different angle? To ask the question in a different way: how are network slices different from virtual network overlays?

To begin, consider the control plane. In the world of virtual topologies, there is generally one control plane that provides reachability, as well as sorting reachability into each virtual topology. For instance, BGP carries a route target and a route discriminator to indicate which virtual topology any particular destination belongs to. A network slice, by contrast, actually has multiple control planes—one for each slice. There will still be one “supervisor control plane,” of course, much like there is a hypervisor that manages the resources of each Continue reading

IDG Contributor Network: 6 ways to manage your data – and team

Decision making comes with its challenges as it’s part of a process of nurturing a variety of perspectives, usually by encouraging discussion and debate. However, when competing points of view are left unmanaged, it can easily – and without warning – digress into an unhealthy conflict. Proponents are often passionate about their views and become blind to certain, inconvenient, facts.Today, data has become a reliable arbiter for such debates. This is why business intelligence (BI) has emerged as crucial to the decision making process. BI provides actionable insights that are based on numbers. A growing number of organizations are recognizing its value. In 2016, 73 percent of businesses increased their analytics capabilities.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Educating the public about security – are we doing it all wrong?

In 2016 consumers were exposed to a larger number of high profile data breaches than any year previously. According to the Breach Level Index, 1,792 data breaches led to almost 1.4 million data records being compromised worldwide, an increase of 86% compared to 2015.
