Can OpenStack Be Viable For Virtual CPE?

Can OpenStack Be Viable For Virtual CPE?

By Charlie Ashton Virtual Customer Premise Equipment (vCPE) is a hot topic right now for companies focused on business opportunities in network virtualization. IHS Infonetics surveyed service providers worldwide and concluded that virtual Business CPE (vBCPE) was the top use case for Network Functions Virtualization (NFV) in 2016.  A report from Analysys Mason concluded that vBCPE can generate new revenue…
Security Vulnerabilities with Fingerprinting: Linux Considerations

Security Vulnerabilities with Fingerprinting: Linux Considerations

By  Tim Radzykewycz Various tools, such as nmap, can be used to help determine what operating system a particular computer is running, based on the network responses it generates to crafted network probes. This is called “fingerprinting.” Fingerprinting is a security concern.  It doesn't make it possible to exploit anything that isn't already exploitable.  However, it significantly trims the search…
Are you DROWNing?

Are you DROWNing?

By Mark Hatle An attack on the SSLv2 protocol, was disclosed this week by security researchers. Visit https://drownattack.com if you want to get straight to the scoop. This is yet another in a long string of attacks on the SSLv2 protocol, including the well publicized Heartbleed issue from a few years ago. This protocol was considered to be so insecure…
What is CVE-2015-7547?

What is CVE-2015-7547?

By Andreea Volosincu Some of the uncovered common vulnerabilities capture the world’s attention to the point of being attributed a nickname (e.g. heartbleed). Others are fixed and get popular just in engineering circles. CVE-2015-7547 is one for engineers to know about. The latest reported common vulnerability has not received a nickname, but this is not to say CVE-2015-7547 isn’t important. Exploring…

More than NFV: Transformations in Networking Bring Challenges and Opportunities

By Charlie Ashton With all the industry hype around Network Functions Virtualization (NFV), it’s easy to lose track of the fact that telecom infrastructure is not the only segment of the networking market that’s undergoing radical transformation. Business of all kinds are benefitting from the wide-ranging evolutions of the networks they depend on. Billions of consumers, most of  whom are…
Two to Tango: When Hardware Met Software

Two to Tango: When Hardware Met Software

By Andreea Volusincu Try going incognito on Google (as if you’re on a covert mission), and type “Why is embedded software so” and see what you get. It’s an interesting a dilemma. Autocomplete is a wonderful thing. You can certainly question how accurately the suggested word fits your search, but it still says a lot about what popular perceptions and…
Long Live the New LTS Kernel

Long Live the New LTS Kernel

By Andreea Volosincu It’s the most wonderful time of the year again! No, it’s not Christmas, but the beginning of a new cycle in the Linux microcosm. A few days ago, the Linux 4.1 kernel has been released, and chosen as the LTS kernel of 2015, becoming the most advanced long-term supported release. This is significant not only because the LTS…

Using VirtIO to Virtualize Storage

By Mark Hermeling Embedded virtualization allows for consolidation of multiple different operating systems on a single box. Our video demonstration combines four different Wind River Linux operating systems onto a single Advantech 2151 board. Combining multiple operating systems together often means that you need to share critical resources. In the above demonstration we show how the Virtualization Profile of VxWorks…

Intel DPDK – A Technology that is Thriving

By Andreea Volosincu For far too many times, the world of open source software gives way to a plethora of standards and reference designs that are supposed to make users’ life easier, improve performance, and security; often making it onto many conference slides as best examples. Some come, some are left behind, but those that manage to stick are continuously…
Break Out and Stay Out with Open Source

Break Out and Stay Out with Open Source

By Andreea Volosincu Let’s talk about the issues around proprietary software and closed ecosystems. Using them keeps your embedded devices enclosed. However, some may come to think there is no better option out there, especially when they’ve seen  how other people have tried to break the proprietary bond but failed. Yes, looking at you Munich! Meanwhile the world continues to innovate…
