Fujitsu tech can track heavily blurred people in security videos

Fujitsu has developed image-processing technology that can be used to track people in security camera footage, even when the images are heavily blurred to protect their privacy.Fujitsu Laboratories said its technology is the first of its kind that can detect people from low-resolution imagery in which faces are indistinguishable.Detecting the movements of people could be useful for retail design, reducing pedestrian congestion in crowded urban areas or improving evacuation routes for emergencies, it said.Fujitsu used computer-vision algorithms to analyze the imagery and identify the rough shapes, such as heads and torsos, that remain even if the image is heavily pixelated. The system can pick out multiple people in a frame, even if they overlap.To read this article in full or to leave a comment, please click here

Amazon opens store on Alibaba to sell imported goods in China

To reach more Chinese consumers, Amazon.com has opened an imported goods store on an Alibaba Group site.The new store will officially launch next month on Alibaba’s Tmall.com site, and will function as a pilot project, Amazon said Friday.Amazon already has its own e-commerce site geared for the country, but its share of China’s online retail market is only 0.8 percent, according to Beijing-based research firm Analysys International.Alibaba, in contrast, controls three quarters of the market through its Tmall and Taobao Marketplace sites, and has 265 million monthly active users.The Chinese market is fiercely competitive, as Amazon is not only competing against Alibaba, but also scores of other smaller e-commerce providers routinely offering promotional deals on products.To read this article in full or to leave a comment, please click here

Hello, I’m 47321

And now the big reveal. The reason I haven’t been blogging or doing much of anything for some time now is because I’ve had a teeny tiny side project going on:

ISIS supporters operated at least 46,000 Twitter accounts, study finds

Supporters of the Islamic extremist group known as ISIS operated at least 46,000 Twitter accounts at the end of last year, a new study says, underscoring the challenge facing social networks as they become powerful tools for propaganda and recruitment.The accounts were in use between September and December, and while not all were active at the same time, the estimate is a conservative one. The actual number could be as high as 70,000, according to the study, which was commissioned by Google Ideas and published by the Brookings Institution, a Washington, D.C., think tank.To read this article in full or to leave a comment, please click here

EVPN. The Essential Parts.

In a blog post back in October 2013 I said I would write about the essential parts of EVPN that make it a powerful foundation for data center network virtualization.  Well just when you thought I'd fallen off the map, I'm back.  :)

After several years as an Internet draft, EVPN has finally emerged as RFC7432.  To celebrate this I created a presentation, EVPN - The Essential Parts, that I hope will be helpful to people who are interested.

Use cases are intentionally left out of this presentation as I prefer the reader to creatively consider whether their own use cases can be supported with the basic features that I describe.

Let me know your thoughts and I will try to expand/improve this presentation or create other presentations to address them.

Self-driving car technology could end up in robots

The development of self-driving cars could spur advancements in robotics and cause other ripple effects, potentially benefitting society in a variety of ways.Autonomous cars as well as robots rely on artificial intelligence, image recognition, GPS and processors, among other technologies, notes a report from consulting firm McKinsey. Some of the hardware used in self-driving cars could find its way into robots, lowering production costs and the price for consumers.Self-driving cars could also help people grow accustomed to other machines, like robots, that can complete tasks without the need for human intervention.Commonly used parts could allow auto mechanics to fix robots as well, said the report, released Thursday. Infrastructure like machine-to-machine communication networks could also be shared.To read this article in full or to leave a comment, please click here

Cisco gets Computer History Museum haven

The Computer History Museum in Mountain View, Calif., this week said it had created a Cisco Archive that promises to document and preserve the networking giant’s impact on the industry and Internet.+More on Network World: What network technology is going to shake up your WAN?+In a blog post, Paula Jabloner the first Director of the newly established Cisco Archive wrote about one of the more significant events the Archive will preserve: “It was 1989. Kirk Lougheed of Cisco and Yakov Rekhter of IBM were having lunch in a meeting hall cafeteria at an Internet Engineering Task Force (IETF) conference. They wrote a new routing protocol that became RFC (Request for Comment) 1105, the Border Gateway Protocol (BGP), known to many as the “Two Napkin Protocol” — in reference to the napkins they used to capture their thoughts.”To read this article in full or to leave a comment, please click here

Apple may offer personal engravings on the Apple Watch

In just a few days, Tim Cook will take the stage and give us the full scoop on all of the Apple Watch details that we've been yearning for. First and foremost, it stands to reason that we'll finally get a pricing matrix for the Apple Watch. Indeed, recent rumors about potential pricing for the device have been all over the map, with some claiming that the gold models of the Edition lineup may cost upwards of $10,000.As for other tidbits, a rumor from the French-language site iPhonote relayed an interesting Apple Watch rumor earlier today, namely that Apple will offer a personal engraving option for buyers.To read this article in full or to leave a comment, please click here

Google’s new car insurance site lets you compare rates

Google has launched a new auto insurance site in the U.S. designed to simplify for consumers the process of shopping for policies.Google Compare Auto Insurance, launched Thursday, is a free site that prompts users to enter the typical sorts of questions for getting an auto quote, like information about the car, the person’s driving history and location. Do that, and then Google spits back a bunch of quotes and coverage details from different providers. From there, Google can link users with the provider of their choice by phone or website, to complete a purchase.People can also access the service through a regular Google search for “car insurance.”To read this article in full or to leave a comment, please click here

What network technology is going to shake up your WAN?

Few areas of the enterprise are as ripe for change as the wide area network. And there are plenty of technologies – from hybrid WAN services and software defined networking to better management tools -- lining up to push such a makeover closer to reality. “There is about as much turmoil in the WAN arena as possible,” said Steve Taylor, senior research fellow with Webtorials.com. You can get the sense of the tumult by taking a look at the vendor activity in all aspects of the WAN. A ton of startups including vendors such as CloudGenix, Glue Networks, Viptela and Velocloud are offering new WAN services and products. Established vendors such as Cisco, Avaya, Alcatel-Lucent and Riverbed are also scrambling to address WAN issues with new software and hardware.To read this article in full or to leave a comment, please click here

Interactions between QoS and IPSec on IOS and the ASA

Quality of Service configuration for the traffic entering/leaving a VPN tunnel may require some special considerations. In this article, I am going to focus on interactions between QoS and IPSec on IOS and the ASA.

There are two methods of deploying QoS for VPNs – you can match the original (Clear-text/ unencrypted) traffic flows or the actual VPN (Aggregate traffic). This second option can be useful when you want to apply a single QoS policy to all packets leaving a tunnel, no matter what are the original sources and destinations protected by the VPN.

We have got a VPN tunnel built between R1 and ASA. R6 and 10.1.1.0/24 are protected networksQosipsecG1

Let’s start on IOS (R1). The VPN tunnel is already up – we will configure a basic QoS Policy to enable LLQ for delay-sensitive traffic, such as Voice (I assume these are all packets with DSCP of EF). Note that this configuration would normally match all EF-colored packets (including non-VPN EF traffic), but since we won’t have any clear-text EF flows in this network we don’t really care:

class-map match-all VOICE
match dscp ef
policy-map QOS
class VOICE
priority

int f0/0
service-policy output QOS

Voice traffic Continue reading

Time To Get More Advanced :: FCIP Pt. 2!

Part 1 of this blog series created a topology, much like you see below, where we configured a single vE (virtual expansion) port from MDS1 to MDS2 across an IP network.  We merged VSAN 10 across this FCIP tunnel and verified it by looking into the FCNS database and ensuring that we saw entries from both sides.  Today we are going to build upon this topology, and get into some more advanced features like changing the default TCP port, setting DSCP values for the two TCP streams, and controlling who initiates the tunnel!

FCIPpt2g1

So first things first…the default port for FCIP is TCP port 3225. We will terminate both of our TCP streams on this port (we have 1 stream for control and another for data traffic). Essentially 1 of the MDS’s will initiate the connection to the other, and their destination port will be TCP/3225. Their source port will be some high-number ephemeral port by default (usually over 65000). We can look at the output of a ‘show int fcip #’ to find out who initiated, and on which ports!

MDS1-6(config-if)# show int fcip1
fcip1 is trunking
Hardware is GigabitEthernet
Port WWN is 20:10:00:0d:ec:1f:a4:00
Peer port WWN is Continue reading

Lawmakers target data brokers in privacy bill

Four U.S. senators have resurrected legislation that would allow consumers to see and correct personal information held by data brokers and tell those businesses to stop sharing or selling it for marketing purposes.The Data Broker Accountability and Transparency Act, introduced by four Democratic senators Thursday, also would require the U.S. Federal Trade Commission to craft rules for a centralized website for consumers to view a list of data brokers covered by the bill.Data brokers collect personal information about consumers, often without their knowledge, and resell it to other businesses.To read this article in full or to leave a comment, please click here
