For most of us, network engineers, the IT world means anything but art. Still, it seems that out there somebody think Wifi can be use to generate art. And they did a pretty good job.
Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen had this idea to explore the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs. A four-metre tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting.
I think all network engineers touched, if not used / patched, as least one time a fiber optic patch cord. As a network engineer you might not necessarily need to understand HOW fiber optic is working. It’s there and it’s working. You just need to plug the patch cord and that that’s it.
Anyway, for interested network engineers (or geeks) like me, to understand how fiber optic works might be a fun way to spend 10 minutes of my life. Of course, to have in-deep knowledge of FO, at the level which allow you to design applications for this transport medium, you need to read a little bit more than the video above.
On March 9, 2010 Cisco announced the Cisco® CRS-3 Carrier Routing System (CRS) designed to serve as the foundation of the next-generation Internet and set the pace for the astonishing growth of video transmission, mobile devices and new online services through this decade and beyond.
With more than 12 times the traffic capacity of the nearest competing system, the Cisco CRS-3 is designed to transform the broadband communication and entertainment industry by accelerating the delivery of compelling new experiences for consumers, new revenue opportunities for service providers, and new ways to collaborate in the workplace.
Check below the amazing features of this device which can support for sure the future technologies:
Total capacity of up to 322 Tbps – 13 times the competition
Proven multichassis architecture with 3-stage fabric
Tried and tested QuantumFlow Array chipset to help prevent bottlenecks
Defining Core and Data Center Services
Built-in service intelligence allows the network and cloud to work as one
Multi-directional capabilities handle traffic between data centers and from core to subscriber
Cloud VPNs automate network connectivity
Defining Cost Savings
Lower cost per Gbps – uses up to 40% power of competitors
Optional modular power system that grows with capacity
Smart design uses the existing CRS-1 chassis and many components, requiring only fabric and line card upgrade

Introducing the Cisco CRS-3 Carrier Routing System by Mr. John Chambers:
I have found this great video material from RouteHub Group regarding IP routing overview. It contains basic about IP routing, why it is needed, how to implement and so on. This material will be really apreciated by the beginners in this area as the explanation is straight forward without using fancy explanation where is not needed. For today you have part 1 from this 4 episodes series.
All this material is produced by RouteHub Group consultants, so all the copyrights and greetings have to be directed to them. If was free shared on the Internet so, I hope that I’m not breaking any copyright rules here. All that i want is to make this material more visible on the Internet. This is true also for the more to come materials from them.
If you are curious who is RouteHub Group, I have found this simple explanation on their site: RouteHub Group is a Premium Cisco Consulting provider of Cisco Products, Solutions, Training, and Professional Services for small, medium, and large-sized businesses.
