Reserved Internal Address Ranges

The
I’ve added a new question to my own network integration checklist, specifically when integrating chassis-based or integrated solutions:

Does the system use any reserved internal address ranges?


Some chassis-based systems reserve private IP address ranges for inter-card communication. This is a perfectly fine setup as long as you, the network integrator, know what ranges are in use. However, you’ll have a frustrating case of ‘disappearing packets’, if you’re not aware that these ranges are in use. 
I first saw this issue  on an IXIA XM12 chassis a few years back. As I later discovered, each line card received a /24 from an RFC1918 address range. The supervisor used an IP address in each range to communicate with each line card. When I used a conflicting range in my testing the chassis would swallow my packets, and I was left scratching my head until I figured this out.
I thought this was a one-off, but I hit it again recently on an Ericsson Call Control Node. Same problem, but a little easier to detect this time. Nevertheless, I’ve been stung twice now on this issue, so I’ve added to my checklist and brought it to your attention.

Report: Comcast and T-Mobile up, AT&T down in latest telecom customer service ratings

An annual customer satisfaction survey says that T-Mobile is now the highest-rated of America’s big four wireless carriers, and that Comcast is no longer the least-popular ISP in the country, among other results.+ALSO ON NETWORK WORLD: New JavaScript spam wave distributes Locky ransomware + Google cleared of infringement in Oracle lawsuit over JavaThe American Customer Satisfaction Index, released today, found that the percentage of users satisfied by T-Mobile’s service rose 6% in year-over-year terms to 74%, while the wireless service provider industry as a whole saw a 1.4% improvement, to 71%.

You’ve been warned: FCC emphasizes that users of authorized wireless gear must obey rules

Just because your wireless equipment is authorized for use by the FCC doesn't mean you can do whatever the heck you please with it, according to an enforcement advisory issued by the commission just before the long weekend (see the entire warning below)."Authorized equipment must be used in a manner that complies with federal law and the Commission’s rules," reads the advisory, in part.While the advisory might appear to be stating the obvious, an FCC spokesman elaborates that "the FCC’s Enforcement Bureau is taking proactive measures to decrease the number of complaints about the use of authorized equipment in a manner that is not compliant with their authorizations.  Reducing complaint volume helps us handle those that do come in in a timely manner. The issue is an ongoing, steady problem."To read this article in full or to leave a comment, please click here

No, it wasn’t just you: Super Mario Bros. is tougher than NP-hard

It’s OK, you’re old enough to admit it – you stunk at Super Mario Bros. The vaunted “feel” of Mario’s movement had you skidding into Koopas and off of cliffs, and the game eventually made you so frustrated that you eventually just played outside instead.And hey, now there’s scientific proof that the game really is just that hard, despite what your friend Jesse – who beat the whole thing with sickening ease – told you. A new paper co-written by researchers at MIT, the University of Ottawa, and Bard College at Simon’s Rock says that Super Mario Bros. belongs to the complexity class PSPACE, meaning it’s more difficult to “solve” algorithmically than the famous traveling-salesman problem or factoring large numbers, which are referred to as NP-hard.To read this article in full or to leave a comment, please click here

Sirin Labs unveils luxury smartphone for security-conscious traveling executives

Today, Sirin Labs announced an ultra-secure luxury smartphone called the Solarin for the international business person who wants both style and security. It will compete with the category of phones produced by Silent Circle, GranitePhone, BlackBerry and Samsung phones with KNOX mobile security software.This is a well-timed introduction, matching the shift to mobile from PCs.Even with price of the Solarin starting at £9,500 (~$13,750), there is a market for smartphones that prove to be impenetrable. That’s because the cost of providing managed services to secure executives’ devices can be quite high. Also, the price of the phone is far less than the cost of a breach should a phone fall into the wrong hands.To read this article in full or to leave a comment, please click here

Hey Rocket Turtle, Pimp My Ride!

This colloquialism for “make my vehicle better” is an appropriate perspective on our recently released Cumulus Linux 3.0, or as we like to say around the office, “3.0.” Our engineering team looked at the upcoming market changes and decided to give Cumulus Linux a pretty sweet makeover.

Screen Shot 2016-05-31 at 1.26.14 PM

Starting with the “IP mindset” that prevails in modern deployments, our team worked with the Linux kernel community to add Virtual Routing and Forwarding (VRF) to the kernel and hardware support to Cumulus Linux. VRF is coupled with BGP unnumbered interfaces as an even simpler way to deploy multi-tenant dual-stack IPv4/IPv6 networks.

In parallel, we looked at the image installation and upgrade mechanisms, revamping the build, packaging, and base installer. As a result, 3.0 is based on Debian 8 (Jessie) and Linux kernel 4.1 tied together with an entire system that enables the development flexibility of Linux coupled with the testing and support required for wide-scale, enterprise production deployments.

All of this functional horsepower is applied to seven new hardware platforms continuing Cumulus Networks’ industry leading support for Open Networking systems. These platforms cover the gamut of speeds, feeds, and functions; introducing Mellanox Spectrum alongside Broadcom Tomahawk and Continue reading

Intel Lines Up ThunderX ARM Against Xeons

The datacenter is a battleground with many fronts these days, with intense competition between compute, memory, storage, and networking components. In terms of revenues, profits, and prestige, the compute territory is the most valuable that chip makers and their system partners are fighting for, and the ARM and OpenPower collectives are doing their best to take some ground from a very powerful Intel.

As such, chip makers end up comparing themselves to Intel Xeon or Atom processors, and Intel sometimes makes comparisons back. At the high end, Intel is battling the Power8 processor championed by IBM and to a lesser …

Could the iPhone lose FaceTime and iMessage?
