What is Layer 0 in the OSI Layers ?

What is Layer 0 in the OSI layers ? Isn’t OSI (Open Systems Interconnection) seven layers?    Yes it is. In the standard, seven layers have been defined. Just let’s remember the seven layers of OSI.   Layer 7: The application layer. Layer 6: The presentation layer. Layer 5: The session layer. Layer 4: The […]

IDG Contributor Network: How immersive technologies will reshape networks

In the late 1990s and early 2000s when it became too difficult for large companies to manage their own WAN footprints, they adopted managed multiprotocol label switching (MPLS) services. These offered a simple connection at every location and offloaded the complexities of building large-scale routed networks from enterprises to the service provider.The advent of cloud computing, however, changed the dynamics of MPLS forever. Enterprises not only needed ubiquitous site-to-site connectivity, but also required better performance from the network to support Software as a Service-based business applications hosted in third-party data centers. In addition, video was becoming a standard mode of communication for corporate meeting and training applications, boosting the need for more bandwidth across the network.To read this article in full or to leave a comment, please click here

IDG Contributor Network: AMP and ThreatGrid Integration into Meraki UTMs

Lately, I have been spending a lot of time on integrating security systems together, and specifically focusing a lot of my energy on Cisco’s Advanced Threat Security product family. (Disclosure: I am employed by Cisco.)Which is what brings me to Cisco’s Advanced Malware Protection (AMP), which is a solution to enable malware detection, blocking, continuous analysis and retrospective actions and alerting.In fact, when the Talos cyber-vigilantes parachute into an environment and performs their forensics analysis and active defense against attacks—AMP is one of the primary tools that they use.To read this article in full or to leave a comment, please click here

The IoT needs simulation to grow

Without simulation, complex systems would fail. Satellites would not reach an accurate orbit, semiconductor circuits would not function, and bridges would not carry the load. Businesses and governments would not invest in these projects without robust simulation software. And without a simulation proving value and functionality, IoT networks of hundreds of thousands or millions of inexpensive devices adding up to large capital investments will not be built.Researchers from the University of Bologna published an analysis of IoT simulation and a smart cities vehicular transportation system case study (pdf). They recommend a networked simulation of orchestrated simulators that model specific IoT features that fit the diversity of IoT devices and use cases.To read this article in full or to leave a comment, please click here

RFC8200: IPv6 Is an Internet Standard

You wouldn’t believe it – after almost 22 years (yeah, it’s been that long since RFC 1883 was published), IPv6 became an Internet standard (RFC8200/STD86). No wonder some people claim IETF moves at glacial speed ;)

Speaking of IPv6, IETF and glacial speeds – there’s been a hilarious thread before Prague IETF meeting heatedly arguing whether the default WLAN SSID should be IPv6-only (+NAT64). Definitely worth reading (for the entertainment value) over a beer or two.

Worth Reading: Do startup employees make more?

Since the average startup founder who makes it to Series A earns more than a large company employee, many believe that early-stage startup employees also earn more (albeit less than founders). Dustin Moskovitz has even claimed that startup early employees have better earnings prospects than founders. We’ve looked at the data, and this does not seem to be true on average. —Ben West @ 80000hours
