NSF and GR on Nexus 5000

NSF and GR are two features in Layer 3 network elements (NEs) that allows two adjacent elements to work together when one of them undergoes a control plane switchover or control plane restart.

The benefit is that when a control plane switchover/restart occurs, the impact to network traffic is kept to a minimum and in most cases, to zero.

Hackers claim to have launched DDoS attack that crashed Pokémon Go servers

Shortly after Pokémon launched in 26 new countries, the servers crashed.

A group of hackers going by “PoodleCorp,” a collective that took credit for hacking popular YouTube channels last month, took to Twitter to claim responsibility for DDoS-ing the Pokémon Go servers.To read this article in full or to leave a comment, please click here

ChefSteps’ Joule: Food meets tech. Result? Delicious!

When I’m not writing about technology or playing wi-, er, testing software or hardware, I cook. Food and cooking are two of my passions and one of the worst things about being in the tech world is that cooking usually has to take second place. Today, however, I have the pleasure of combining tech with my culinary pursuits as I recently got my hands on a really cool cooking device that’s Bluetooth and Wi-Fi enabled and controlled by a smartphone app. The device is an immersion circulator called Joule that was developed by one of my favorite foodie resources, ChefSteps. To read this article in full or to leave a comment, please click here

AT&T wants to keep order in drone-filled skies

When it comes to drones, AT&T wants to be in the driver’s seat.The massive U.S. carrier is already using drones to inspect its cell towers and may someday put cells on drones to boost service at big events. But it’s also eyeing a major role in the way others use drones.At the heart of it all is AT&T’s network, technology executives from the company said Friday at AT&T’s Shape conference in San Francisco. They see the network as a future backbone for command and control of drones or even a drone traffic management system.To read this article in full or to leave a comment, please click here

During coup attempt, Turkish president appears via Facetime on live TV

In what may be another first for our connected world, Turkish President Recep Tayyip Erdogan placed what appeared to be a Facetime call to a national news broadcast early on Saturday while the world tried to figure out if a military coup against him had succeeded. Erdogan appeared on a journalist's iPhone, held up to the camera so viewers could see and hear what he had to say. He claimed that he remained in control and urged the public to take to the streets to oppose the coup attempt. Erdogan's use of modern technology to speak to the nation comes with a heap of irony. He has been keen to shut off access to the Internet during sensitive times and go after those who try to get around such bans and those who insult him. Reporters Without Borders says Erdogan has "systematically" censored the Internet.To read this article in full or to leave a comment, please click here

Worth Reading: What we lose when we photograph life instead of experiencing it

Increasingly, images have become a crucial part of communicating with others, receiving affirmation and documenting new experiences. And though it may seem that a barrage of colors and pixels and faces and scenery could only enrich our imaginations and enhance our engagement with the world, the opposite seems to be taking place. —Intellectual Takeout

Democratizing Capacity (or How to Interpret Cisco math)

Mid-December, Cisco held its Financial Analysts Conference. Shortly thereafter, I was fielding questions that summed up to “What is this all about? Cisco is cheaper than bare-metal? Really?”; check out slide 4 in this presentation.

Let me begin by clarifying that Cisco is not more affordable. Period. We’ll get to that analysis a bit later… the bigger point is that bare-metal networking is more than being affordable; it’s about giving customers degrees of freedom, transparency, and choice that they deserve in a mature industry.

In the dark ages of computing (aka 1983), a customer running IBM DB2 had to buy an IBM mainframe (complete with cables, disks, power distribution, memory, and IO) to go with the application. The compute industry has matured to a point where DB2 runs on hardware ranging from mainframes through p-series down into non-IBM x86 platforms hosted on operating systems including z/OS, Unix, Linux, and Windows. Application independent from OS independent from hardware; degrees of freedom and choice.

Circling back to networking, a significant number of products today, including Cisco’s Nexus 3000 and Nexus 9000 platforms, are based on industry prevalent networking silicon from companies like Broadcom. Optics and cables branded by networking incumbents are Continue reading

Use Tor? Riffle promises to protect your privacy even better

Privacy-minded people have long relied on Tor for anonymity online, but a new system from MIT promises better protection and faster performance.Dubbed Riffle, the new system taps the same onion encryption technique after which Tor is named, but it adds two others as well. First is what's called a mixnet, a series of servers that each permute the order in which messages are received before passing them on to the next server.To read this article in full or to leave a comment, please click here
