The Longest Match Rule

One of the the concepts that comes up occasionally is that of precedence. For example, one might consider the following routing table entries.

ip route 0.0.0.0 0.0.0.0 1.1.1.1              //default route
ip route 192.168.0.0 255.255.0.0 1.1.1.2      //supernet/cidr route
ip route 192.168.1.0 255.255.255.0 1.1.1.3    //network route
ip route 192.168.1.0 255.255.255.128 1.1.1.4  //subnet route
ip route 192.168.1.20 255.255.255.255 1.1.1.5 //host route

Questions often arise around which path a packet would take when it matches more than one entry. For example, a packet may have a destination address of 192.168.1.20. In this case it matches every single route entry.

The logic is actually simple, even straightforward. A packet will follow the most specific route entry that it matches. So a packet destined to 192.168.1.20 would be routed to a router at 1.1.1.5. If the destination happened to be 192.168.1.21, it would be routed over to 1.1.1.4.

Chip companies working to make Wi-Fi more maker-friendly

Texas Instruments and MediaTek have launched new offerings aimed at making it easier to build IoT (Internet of Things) devices with Wi-Fi connectivity.The chip makers have realized that their future isn't just in selling products to big companies, but also to a growing maker community whose products also need Wi-Fi connectivity.This week TI expanded its SimpleLink portfolio with two new modules, which promise to help add Wi-Fi connectivity without requiring any network experience. A similar promise came from MediaTek earlier this month when it launched a new Wi-Fi development platform.INSIDER: 5 ways to prepare for Internet of Things security threats To jump start Wi-Fi development, TI now offers the CC3100 module BoosterPack and the CC3200 module LaunchPad, which include an SDK and sample boards that can be connected directly to a PC.To read this article in full or to leave a comment, please click here

Python and Jinja2 Tutorial

“How should I get started with Network Automation?” I am often asked this question by network engineers looking to build new programming skills.

Apple Car to be released in 2020, report claims

In just a week's time, the news cycle around Apple has transitioned from the impending launch of the Apple Watch to reports that the company is actively working to develop an electric car.More than just an anonymously sourced rumor, a number of reputable publications have all reported that Apple is looking to get into the car industry. Tthe Wall Street Journal, for example, reported a few days ago that Tim Cook has already authorized the development of a 1,000 strong team to get things rolling.Stoking the Apple car rumors considerably is a recent report from Bloomberg which relays that Apple has designs to begin vehicle production as early as 2020. Now given that the car manufacturing process for a veteran automaker-- from design to production -- can often take upwards of 7 years, a five year time frame for a newbie like Apple seems curiously short.To read this article in full or to leave a comment, please click here

PlexxiPulse—Simply A Better Network

Nashua Telegraph: Plexxi likes the Nashua network
By David Brooks
There are plenty of reasons to locate a tech startup in one place rather than another. For networking firm Plexxi, part of Nashua’s appeal is institutional memory. “There’s definitely a talent base up here, from the days of Wang, DataGeneral and Digital. That’s a very complex, system-oriented world, ” said Rich Napolitano, who has been CEO since November, and whose first job out of college was at Digital Equipment Corp. in almost the same building where Plexxi now resides.

Google agrees to Italian privacy authority audits in the US

Google has agreed to on-the-spot audits at its U.S. headquarters in order to comply with Italy’s data protection laws.The Italian data protection authority (DPA) imposed several privacy measures on Google after an investigation into the company’s policies that was completed in July 2014. On Friday, the authority said Google will comply with all demands.The process to verify compliance calls for the DPA to check up on Google’s progress at its U.S. headquarters. It remains unclear when that will happen, though. “There is no precise appointment at the moment but there is an agreement to be able to go there,” a spokesman for the authority said.To read this article in full or to leave a comment, please click here

Enabling and Mounting NFS on CoreOS

I’ve written about CoreOS a fair amount (see here, here, and here), but one of the things that is both good and bad about CoreOS is the automatic update mechanism. It’s good because you know your systems will stay up to date, but it’s bad if you haven’t taken the time to properly address how automatic updates will affect your environment (for example, you’ve manually started some Docker containers instead of using systemd unit files—when the CoreOS system reboots after an update, your Docker containers will no longer be running). Re-architecting your environment to fully account for this change in architecture and behavior is a larger discussion than can be addressed in a single blog post, but in this post I want to at least tackle one small part of the discussion: separating your persistent data. In this post, I’ll show you how to mount an NFS share on a CoreOS instance deployed on OpenStack (or any cloud that leverages cloud-init).

Now, you could probably go into your CoreOS instance and manually make these changes, but that’s still thinking the old way. In addition to thinking about keeping persistent data separate, we (data center/cloud architects) also need Continue reading

Networking Field Day – Afterthoughts – New SolarWinds features.

One thing I really liked about SolarWinds was the fact they were the first vendor to start with a white board discussion. Being a network engineer I am a big fan of drawing boxes and lines on a white board. To me it is a more engaging way to have a presentation compared pre-built […]

Sensors and lasers will help Volvo’s self-driving cars stay on the road

A complex network of sensors, lasers and a cloud-based positioning system are part of a plan from Volvo Cars to have 100 self-driving cars on the road by 2017.Volvo’s project to put self-driving cars on the streets of Gothenburg is entering its second year. It aims to let ordinary people drive a car with an autopilot in normal traffic on public roads. On Thursday, Volvo gave some insights into the technology it will use to integrate self-driving cars into real traffic.“The key to success is combining sensors, computers and a chassis system in a clever way,” said Erik Coelingh, a technical specialist at Volvo.To read this article in full or to leave a comment, please click here

IoT network will look to the skies for better coverage

Wide-area wireless networks for connecting Internet of Things devices may go global through a partnership between hot IoT startup Sigfox and aerospace company Airbus.Sigfox builds long-range networks for devices such as sensors that need a wireless connection but are too small and power-constrained for cellular radios. Its networks use unlicensed frequencies and don't go more than a few hundred bits per second, but they cost as little as US$1 per connection, per year.The French company has now joined the Mustang Project, co-founded by Airbus Defence and Space and two R&D partners in France. The project plans to combine Sigfox's terrestrial networks with satellite coverage to achieve global coverage.To read this article in full or to leave a comment, please click here
