NANOG - the art of running a network and discussing common operational issues

The North American Network Operators Group (NANOG) is the loci of modern Internet innovation and the day-to-day cumulative network-operational knowledge of thousands and thousands of network engineers. NANOG itself is a non-profit membership organization; but you don’t need to be a member in order to attend the conference or join the mailing list. That said, if you can become a member, then you’re helping a good cause.

The next NANOG conference starts in a few days (February 6-8 2017) in Washington, DC. Nearly 900 network professionals are converging on the city to discuss a variety of network-related issues, both big and small; but all related to running and improving the global Internet. For this upcoming meeting, Cloudflare has three network professionals in attendance. Two from the San Francisco office and one from the London office.

With the conference starting next week, it seemed a great opportunity to introduce readers of the blog as to why a NANOG conference is so worth attending.

Tutorials

While it seems obvious how to do some network tasks (you unpack the spiffy new wireless router from its box, you set up its security and plug it in); alas the global Internet is somewhat more complex. Continue reading

Cost optimization gains ground in IT infrastructure decisions

In business, as in life, a great deal of time is spent predicting the future, especially at the dawn of a new year. Market watchers are scrambling to identify the top IT trends that will shape buying patterns in 2017. Amid all the data gathering and crystal-ball gazing, I prefer to look back and learn from what’s happened in the past so I’ll be better prepared to handle what lies ahead. Last month, I attended the Gartner Data Center, Infrastructure & Operations Management Conference, which never fails to deliver an insider’s look at the latest priorities, challenges and transformations in the corporate data center. This past conference provided lots of valuable insight, especially when it came to the topic of cost optimization. To read this article in full or to leave a comment, please click here

Home products that fix/mitigate bufferbloat…

My new years resolution is to restart blogging.

Trying to steer anything the size of the Internet into a better direction is very slow and difficult at best. From the time changes in the upstream operating systems are complete to when consumers can buy new product is typically four years caused by the broken and insecure ecosystem in the embedded device market. Chip vendors, box vendors, I’m looking at you… So much of what is now finally appearing in the market is based on work that is often four years old. Market pull may do what push has not.

The fq_codel & cake work going on in the bufferbloat project is called SQM – “smart queue management.”

See What to do About Bufferbloat for general information. And the DSLReports Speedtest makes it easy to test for bufferbloat. But new commercial products are becoming increasingly available.  Here’s some of them.

Evenroute IQrouter

First up, I’d like call out the Evenroute IQrouter. DSL users have often suffered more than other broadband users, due to bad bloat in the modems compounded by minimal bandwidth, so the DSL version of the IQrouter is particularly welcome.   Often DSL ISP’s seem to have the tendency (more Continue reading

Raspberry Pi roundup: Secret messages from your washing machine, smelling the fruit, and Rubik’s Cubes

The one-time pad, familiar from a thousand spy novels, is still among the most secure possible ways to encode a message to keep it safe from prying eyes. A cipher based on truly random numbers, with the keys held only by the sending and receiving parties, is theoretically unbreakable.And thanks to the Raspberry Pi, your messages to the Glorious Motherland can be proof against western imperialist snooping – the Pi, according to an article by Nate Drake for Techradar, is a pretty good source of randomness, and can generate its own sequences of gibberish numbers, which you can print out using an Adafruit Printer and use.To read this article in full or to leave a comment, please click here

WhatsApp reduces spam, despite end-to-end encryption

Can a spam filter work even without reading the content of your messages?WhatsApp thinks so. Since last April, the messenger app has been successfully fighting spam abuse, even as it’s been using end-to-end encryption.That encryption means that no one -- not even WhatsApp -- can read the content of your messages, except for the recipient.More privacy, however, can raise issues about spam detection. If WhatsApp can’t scan your messages for suspicious content, say for advertisements peddling cheap Viagra, then how can it effectively filter them out?To read this article in full or to leave a comment, please click here
