WAN Impairment/WAN Emulator with WAN Bridge

Playing in the lab and want to impair a link with delay or loss?      I use WAN Bridge – its simple and free.

So say I’m testing an SD-WAN brownout/impairment avoidance solution in my lab.  For example, Cisco’s IWAN.  I’m going to need something to impair links with delay or loss.  I like WAN Bridge.  Why?  Because its simple, easy, and free.

There has been one thing I’ve struggled with in the past year about.  Every time I needed an impairment point this burned up 2 NICs on my UCS equipment.  Why? Cause I couldn’t seem to figure out how to load one NIC on a UCS as a trunk port with multiple VLANs on it and have multiple WAN bridges with just 1 trunk on a switch.

So that meant, for a recent CPOC that I was doing, if I really wanted 6 impairment points (red circles in diagram below) I was going to need to eat up 12 NICs on my UCS.

There had to be a better way…..

My friend, David Prall, was convinced it “should” work. I was equally convinced that I had tried it before and Continue reading

Larry Ellison says Amazon is ’20 years behind’ Oracle

Larry Ellison continued his assault on Amazon during his second keynote address at Oracle OpenWorld on Tuesday."Amazon Web Services are simply not optimized for the Oracle Database. I'll go further than that: Amazon Web Services aren't optimized for their own databases either, as you will see," he said, while showing off a set of benchmarks that showed Oracle Database performing several times faster on Oracle's cloud than it does on Amazon's cloud. "It doesn't get better, it gets worse."To read this article in full or to leave a comment, please click here

D-Wave will ship a 2,000-qubit quantum computer next year

Forget PCs and servers: D-Wave Systems is looking into the future with its quantum computer, up to 1,000 times faster than an earlier model.The company will start shipping a quantum computer with 2,000 qubits, twice the size of its current 1,000-qubit D-Wave 2X. The D-Wave 2X is considered one of the most advanced computers in the world today.The 2,000-qubit quantum computer will be 500 to 1000 times faster than its predecessor, said Jeremy Hilton, senior vice president of systems at D-Wave.An even larger quantum computer based on a whole new processor design will come out two to three years after that, Hilton said.Today's PCs and servers could ultimately be replaced by a quantum computer, which has been researched for decades. Beyond D-Wave, companies like IBM are also building quantum computers.To read this article in full or to leave a comment, please click here

There are just 28 internet domains on North Korea’s DNS

The internet in North Korea is an unsurprisingly small and circumscribed place – there are just 28 TLDs on the entirety of the country’s .kp domain, compared to almost 335 million globally.A misconfiguration early Tuesday morning allowed outsiders to get a rare look into the hermit kingdom’s vestigial online infrastructure, which is connected to the broader internet via China. It was detected by the TLDR Project, an automated, ongoing effort to track all global zone transfer requests among DNS providers, and log them to GitHub.+ALSO ON NETWORK WORLD: Why this hospital is moving to Amazon’s cloud + Be careful not to fall for these ransomware situationsTo read this article in full or to leave a comment, please click here

Worth Reading: laptop killing USB stick

For just a few bucks, you can pick up a USB stick that destroys almost anything that it’s plugged into. Laptops, PCs, televisions, photo booths — you name it. Once a proof-of-concept, the pocket-sized USB stick now fits in any security tester’s repertoire of tools and hacks, says the Hong Kong-based company that developed it. It works like this: when the USB Kill stick is plugged in, it rapidly charges its capacitors from the USB power supply, and then discharges — all in the matter of seconds. —ZDNet

Apple delivers free macOS Sierra upgrade

Apple today released Sierra, 2016's edition of the Mac's operating system. Sierra is the first under the "macOS" label Apple introduced in June when it retired the older "OS X" and synchronized the Mac's moniker with other operating systems from the Cupertino, Calif. company, like the iPhone's iOS and the Apple TV's tvOS. Also known as macOS 10.12, Sierra's launch followed the first "golden master," or GM build, by two weeks. Sierra was available Tuesday for free download from the Mac App Store. Although the upgrade was not immediately visible on the front page of the e-mart, a search using sierra quickly located the 4.8GB installation file.To read this article in full or to leave a comment, please click here

Oracle’s infrastructure business focuses on bare metal to go after AWS

Larry Ellison made a splash this week when he said that Oracle would give Amazon a run for its money in the cloud. Then, the company outlined the pillar of the tech titan's infrastructure offering: beefy, bare-metal servers running in the cloud. That's right: Oracle is going after a market that's full of virtualized workloads with servers that clock in with a whopping 36 physical CPU cores, according to Vice President of Engineering Don Johnson. Rather than starting from the low end of the infrastructure market and working its way up, Oracle is starting at the top and working its way down. To read this article in full or to leave a comment, please click here

Can I2RS Keep Up? (I2RS Performance)

What about I2RS performance?

The first post in this series provides a basic overview of I2RS; there I used a simple diagram to illustrate how I2RS interacts with the RIB—

One question that comes to mind when looking at a data flow like this (or rather should come to mind!) is what kind of performance this setup will provide. Before diving into the answer to this question, though, perhaps it’s important to ask a different question—what kind of performance do you really need? There are (at least) two distinct performance profiles in routing—the time it takes to initially start up a routing peer, and the time it takes to converge on a single topology and/or route change. In reality, this second profile can be further broken down into multiple profiles (with or without an equal cost path, with or without a loop free alternate, etc.), but for our purposes I’ll just deal with the two broad categories here.

If your first instinct is to say that initial convergence time doesn’t matter, go back and review the recent Delta Airlines outage carefully. If you are still not convinced initial convergence time matters, go back and reread what you can Continue reading

TLS 1.3 gets early adoption boost through CloudFlare

Website security and performance vendor CloudFlare has made the newest version of the TLS secure communications protocol available to all of its customers.The TLS (Transport Layer Security) 1.3 specification is yet to be finalized by the Internet Engineering Task Force (IETF), the body that develops internet standards. However, the protocol is already supported in beta versions of Google Chrome and Mozilla Firefox, and it's being hailed as an important step forward in securing internet communications.TLS 1.3 removes some cryptographic algorithms present in TLS 1.2 that are known to be vulnerable. This makes it easier for server administrators to deploy secure-by-default HTTPS configurations. HTTPS (HTTP Secure) is a mix between HTTP and TLS.To read this article in full or to leave a comment, please click here

Stanford researchers invent tech workaround to net neutrality fights

Engineers at Stanford University have invented a new technology that would give broadband customers more control over their pipes and, they say, possibly put an end to a stale net neutrality debate in the U.S.The new technology, called Network Cookies, would allow broadband customers to decide which parts of their network traffic get priority delivery and which parts are less time sensitive. A broadband customer could then decide video from Netflix should get preferential treatment over email messages, for example.The technology could put an end to the current net neutrality debate focused on whether broadband providers are allowed to prioritize some network traffic and block or degrade other traffic, said the researchers, Professors Nick McKeown and Sachin Katti and electrical engineering grad student Yiannis Yiakoumis.To read this article in full or to leave a comment, please click here
