Extreme, NRG Stadium score big with Super Bowl Wi-Fi performance

Super Bowl LI will be remembered for a number of things. The Patriots had the largest comeback in Super Bowl history. Like all Atlanta sports teams, the Falcons choked when it mattered most. Also, Tom Brady won his fifth Super Bowl to cement his place as the second greatest QB of all time, behind the illustrious Joe Montana. More importantly though, Super Bowl LI was the most connected and engaged sporting event to date, as the fans in NRG Stadium in Houston appeared to be very busy using their phones to take pictures, Tweet, Facebook, send messages and other activities. A year ago, I wrote a post about how the network performed for Super Bowl 50, so I thought it would be worth looking at how things changed between then and now. To read this article in full or to leave a comment, please click here

BigSecure + A10 TPS: Dynamic, Scale-out DDoS Attack Mitigation

IDG Contributor Network: Coder turns AWS IoT Button into ACLU donation button

During World War II, President Franklin Roosevelt ordered people of Japanese descent, many American citizens, to be relocated to internment camps. Even those with as little as one-sixteenth Japanese blood were interned. Over 110,000 Japanese Americans from California, Oregon, Washington and Arizona were affected. Many had just six days to sell all their possessions before being interned!President Ronald Reagan signed the Civil Liberties Act in 1988, which apologized for the internment on behalf of the U.S. government. The legislation admitted that government actions were based on "race prejudice, war hysteria, and a failure of political leadership."To read this article in full or to leave a comment, please click here

Python – Kirk Byers Course Week 1 Part 2

In the second part of assignments for the first week of Kirk Byers Python for Network Engineers class we will be working with IPv6 addresses.

We start with the following IPv6 address: FE80:0000:0000:0000:0101:A3EF:EE1E:1719.

The goal is then to split this address into individual parts. The delimiter in an IPv6 address is a colon. For an IPv4 address we would have used a dot instead. Python has a built-in function for splitting strings. To split the address we use this function and tell Python that a colon is our delimiter.

print("IPv6 address split:")
print(ipv6_split)
print(type(ipv6_split))

This means that we have turned our string into a list, consisting of eight parts of the IPv6 address.

daniel@daniel-iperf3:~/python/Week1$ python3 ipv6.py 
IPv6 address split:
['FE80', '0000', '0000', '0000', '0101', 'A3EF', 'EE1E', '1719']
<class 'list'>

To rejoin the address again the built-in function “join()” will be used. The syntax for this function is a bit awkward besides that it’s easy to use.

ipv6_new = ":".join(ipv6_split) 

print("IPv6 address rejoined:") 
print(ipv6_new) 
print(type(ipv6_new))

First we tell Python to put a colon between all the parts we are joining. The output then looks like this:

daniel@daniel-iperf3:~/python/Week1$ python3 ipv6.py 
IPv6 address rejoined:
FE80:0000:0000:0000:0101:A3EF:EE1E:1719
<class 'str'>

IDG Contributor Network: Intel report suggests that self-service IT is a huge security risk

Ever since cloud computing was introduced a decade or so ago, there has been much gnashing of teeth and wailing about the security risks that the cloud introduced. Back in the old days, these arguments were pretty simple and revolved around control. Since then, however, as cloud adoption has become more widespread, we have had more nuanced views about cloud risks. But still, there are those traditional IT folks who balk at the very mention of the cloud. To them, cloud is anathema that is diametrically opposed from their stated objective of delivering the best outcome with the highest levels of safety for the business. Of course, many people would suggest that a significant proportion of those bemoaning the risks of the cloud are actually bemoaning the fact that their career prospects look less rosy in a cloudy world, and that it is self-interest that drives this message.To read this article in full or to leave a comment, please click here

No-Hassle Hardware Replacement with DCNM

Continuing my look at Cisco’s Data Center Network Manager (DCNM) software, I had to swap out a faulty spine switch recently, and got a chance to find out whether I could use DCNM to make the RMA process a little less painful than it would normally be.

Using DCNM for RMA

If I had a dream, albeit a rather sad one, it would be to be able to swap out a hardware component in my network quickly and efficiently, and not have to mess around.

DCNM has all the elements to make this feasible. Given a device serial number, I’ve already confirmed that DCNM can automatically deploy the correct firmware version and base configuration when deploying a new fabric, so there’s no reason it couldn’t be used to do the same thing for a replacement switch, but this time deploying the complete, production configuration in one step. Happily I already have the configuration for the spine switch I’m replacing, because DCNM takes frequent backups. I also have the appropriate firmware loaded to DCNM’s software repository because I used it to build the fabric in the first place. So how do I approach the RMA?

Telling DCNM About The New Hardware

Once the replacement switch was received Continue reading

BrandPost: How to Sidestep Common Enterprise Storage Mistakes

While the move toward truly digital environments provides IT with an exciting opportunity to contribute to the organization’s future, it also increases the workload on IT infrastructure. And when resources are taxed, mistakes are made. Unfortunately, the process of building storage environments capable of satisfying the demands of the new digital economy isn’t exempt.Some mistakes are understandable, painless, and easy to correct. But others can be harmful enough to put your company on the path to failure – especially if left unaddressed. Here are three prime examples of common storage mistakes and how you can avoid them.Mistake 1: Undervaluing the role visibility plays in today’s digital environment. When always-on performance is a prerequisite, failing to embrace visibility tools means that you are essentially operating in the dark and surviving on chance. Dynamic visibility tools combined with a Fibre Channel-based storage fabric can give you the ability to rapidly troubleshoot current or looming problem areas.To read this article in full or to leave a comment, please click here

Top Chinese Supercomputer Blazes Real-World Application Trail

China’s massive Sunway TaihuLight supercomputer sent ripples through the computing world last year when it debuted in the number-one spot on the Top500 list of the world’s fastest supercomputers. Delivering 93 teraflops of performance – and a peak of more than 125,000 teraflops – the system is nearly three times faster than the second supercomputer on the list (the Tianhe-2, also a Chinese system) and dwarfs the Titan system Oak Ridge National Laboratory, a Cray-based machine that is the world’s third-fastest system, and the fastest in the United States.

However, it wasn’t only the system’s performance that garnered a lot …
