BRKRST-2042 — Highly Available Wide Area Network Design

Presented by: David Prall, Communications Architect, Cisco For reference, David is the “father of IWAN”. This session was not what I was expecting. I was expecting design and architecture, but it was all about features in IOS and IOS-XE (eg, FHRPs, talked about routing protocol timers, PfRv3, BFD). I guess I need to pay more attention to the session code (RST == routing; ARC == architecture).

BRKNMS-2701 – How I Learned to Stop Worrying and Love Prime Infrastructure

Presenters:

  • Lewis Hickman, Consulting Systems Engineer
  • Jennifer Valentine, Systems Engineer


Quick survey in the room: 60-70% of attendees running PI 3.x; 10-20 PI 2.x; some still on LMS.

“There are 37 different ‘Cisco Prime’ products” — Lewis

“Cisco Prime” isn’t a product; “Cisco Prime Infrastructure” is. Cisco Prime is a family of products.

PI traces its lineage back to 1996: CWSI > Cisco Works LMS > Cisco Prime LMS > WCS > NCS > Prime Infrastructure.

“1232 SysObjIds supported in PI today” — Lewis (aka, 1232 different devices supported by PI)

Two people (only!!) in the room running Network Analysis Module.

UCS Server Assurance module: enables mgmt of UCS servers; will integrate into vCenter and map VMs to physical hosts for you. 

Operations Center: manager of managers for PI

Licensing in PI 3.x:

  • One license for Lifecycle and Assurance now
  • Different license files for different device types
  • Different device types require a specific number of “tokens”
  • When a license is installed in PI 3.x, it gets converted into the appropriate number of tokens
  • As you add devices to PI, it draws down on the number of free tokens in the pool
  • Hint: You don’t Continue reading

Hacked 3D printers could commit industrial sabotage

3D printers can churn out toys, clothing and even food. But the technology also shows potential for use in industrial sabotage, researchers warn.Imagine a car maker using 3D printers to manufacture components, only to have the parts contain defects that are undetectable until it’s too late.A hacker with access to the 3D printers could make that happen, a team of researchers wrote in a recent paper. This could result in a "devastating impact" for users and lead to product recalls and lawsuits, said New York University professor Nikhil Gupta, the lead author of the paper. To read this article in full or to leave a comment, please click here

Google’s AI is learning how to save your life

AlphaGo's uncanny success at the game of Go was taken by many as a death knell for the dominance of the human intellect, but Google researcher David Silver doesn't see it that way. Instead, he sees a world of potential benefits.As one of the lead architects behind Google DeepMind's AlphaGo system, which defeated South Korean Go champion Lee Se-dol 4 games to 1 in March, Silver believes the technology's next role should be to help advance human health.To read this article in full or to leave a comment, please click here

Worth Reading: Measuring IPv6 from the Internet’s core

Measuring the state of IPv6 deployment is difficult, particularly when there are so many different measurement tools out there offering different stats. APNIC Labs shows global IPv6 deployment at 6% while Google shows it at 12%, why such disparity? The answer is because they are measuring from different vantage points on the network. —APNIC

IDG Contributor Network: Using brain signals instead of passwords to unlock computers

System authentication could one day be widely achieved through brainwaves, scientists say. Simply thinking of certain things, such as a person's face, or a rotating displayed cube would be enough to unlock a device.Electro-encephalography (EEC) sensors are behind the technique. That’s where electrical activity in certain parts of the brain is recorded. We know it as the wavy, graphical lines on charts created from wired electrodes placed on the scalp, as seen in hospitals and TV shows. They're used in that environment to diagnose epilepsy, among other things.+ Also on Network World: 5 things you should know about two-factor authentication +To read this article in full or to leave a comment, please click here

Shifting the cost of security

If you deal with enterprise systems security, you likely have an idea what your annual expenditure for security and forensic security is. It’s huge. It’s a time and resource suck like few others. The licensing costs will vary, but they’re a considerable fraction of most organizations’ annual IT spend. Ready-made modular costs are platform-dependent. In Windows, it might be a framework from Symantec, Intel Security, or a host of others. Integration into Active Directory isn’t so much difficult as it is tedious. If you start or add Linux, the cost shifts towards any number of frameworks that require at least a moderate amount of labor costs in customization, maintenance and ongoing platform mods.To read this article in full or to leave a comment, please click here

Killing the password: FIDO says long journey will be worth it

The FIDO (formerly Fast Identity Online) Alliance is out to kill the password.It wouldn’t seem to be a tough sales job. There is little debate among security experts that passwords are a lousy, obsolete form of authentication.The evidence is overwhelming. Most people in spite of exhortations to use long, complicated passwords, to change them at least monthly and to avoid using the same one for multiple sites, don’t.The latest Verizon Data Breach Incident Report (DBIR) found that 63 percent of all data breaches involved the use of stolen, weak or default passwords.To read this article in full or to leave a comment, please click here

BGP Code Dive (3)

This week, I want to do a little more housekeeping before we get into actually asking questions of the bgp code. First there is the little matter of an editor. I use two different editors most of the time, Notepad++ and Atom.

  • Notepad++ is a lightweight, general purpose text editor that I use for a lot of different things, from writing things in XML, HTML, CSS, Python Javascript, C, and just about anything else. This is an open source project hosted on the Notepad++ web site with the code hosted at github.
  • Atom is a more GUI oriented “programmer’s editor.” This is a more full featured editor, going beyond basic syntax highlighting into projects, plugins that pull diffs in side by side windows, and the like. I don’t really have a build environment set up right now, so I don’t know how it would interact with compiled code, but I assume it would probably have a lot of the tricks I’m used to, like being able to trace calls through the code, etc. Atom is available here.

I haven’t actually chosen one or the other—I tend to use both pretty interchangeably, so you’re likely to see screen shots from Continue reading
