Strong Opinions, Loosely Held
I do receive feedback that I express strong opinions. Some people even make that sound like a negative thing. In my networking career, my core value proposition was to develop a strong opinion to suggest, explain and justify spending millions of company dollars.

The Week in Internet News: Placing Money on AI
AI manages your money: Artificial Intelligence may eventually replace your financial advisor, Forbes suggests. AI can already spot financial trends really fast, but it may eventually compete with the personal touch of a human advisor, the story says. “Because artificial intelligence learns so much faster than humans, it is simply a matter of time before artificial intelligence can read human nuances and have an emotional intelligence quotient that exceeds those of most humans. When that happens, in the next few years, financial advisers will have a hard time competing based on personal relationships.”
Banning news: Russia has moved to ban what the government defines as fake news, joining several other countries headed in the same direction, the Boston Globe reports. A second law bans the publication of information showing disrespect to government bodies and officials. The fake news law allows fines of up to US$15,000.
Less fake, more news: Despite headlines about the spread of fake news during the 2016 U.S. elections, a majority of U.S. residents didn’t see fake news on social media, two recent studies suggest. On Twitter, fake news appeared on the feeds of just 1.1 percent of users, according to one study detailed in Continue reading
Another Year of SIP Trunk Provider Problems
In its eighth-annual SIP survey, The SIP School finds that SIP trunking problems persist.
Last Week on ipSpace.net (2019W4)
The crazy pace of webinar sessions continued last week. Howard Marks continued his deep dive into Hyper-Converged Infrastructure, this time focusing on go-to-market strategies, failure resiliency with replicas and local RAID, and the eternal debate (if you happen to be working for a certain $vendor) whether it’s better to run your HCI code in a VM and not in hypervisor kernel like your competitor does. He concluded with the description of what major players (VMware VSAN, Nutanix and HPE Simplivity) do.
On Thursday I started my Ansible 2.7 Updates saga, describing how network_cli plugin works, how they implemented generic CLI modules, how to use SSH keys or usernames and passwords for authentication (and how to make them secure), and how to execute commands on network devices (including an introduction into the gory details of parsing text outputs, JSON or XML).
The last thing I managed to cover was the cli_command module and how you can use it to execute any command on a network device… and then I ran out of time. We’ll continue with sample playbooks and network device configurations on February 12th.
You can get access to both webinars with Standard ipSpace.net subscription.
The case for network-accelerated query processing
The case for network-accelerated query processing Lerner et al., CIDR’19
Datastores continue to advance on a number of fronts. Some of those that come to mind are adapting to faster networks (e.g. ‘FARM: Fast Remote Memory’) and persistent memory (see e.g. ‘Let’s talk about storage and recovery methods for non-volatile memory database systems’), deeply integrating approximate query processing (e.g. ‘ApproxHadoop: Bringing approximations to MapReduce frameworks’ and ‘BlinkDB’), embedding machine learning in the core of the system (e.g. ‘SageDB’), and offloading processing into the network (e.g KV-Direct) — one particular example of exploiting hardware accelerators. Today’s paper gives us an exciting look at the untapped potential for network-accelerated query processing. We’re going to need all that data structure synthesis and cost-model based exploration coupled with self-learning to unlock the potential that arises from all of these advances in tandem!
NetAccel uses programmable network devices to offload some query patterns for MPP databases into the switch.
Thus, for the first time, moving data through networking equipment can contributed to query execution. Our preliminary results show that we can improve response times on even the best Continue reading
Arista BGP EVPN – Configuration Example
This is a follow-up to my previous article, Arista BGP EVPN Overiew and Concepts. In the previous article, I discussed some terminologies and behavior of EVPN and the reason why EVPN is valuable in Data Center and Campus networks. Since then, I’ve learned how valuable it is in Service Provider networks as well, but I’ll […]

A Discussion On Storage Overhead
Let’s talk about transmission overhead.
For various types of communications protocols, ranging from Ethernet to Fibre Channel to SATA to PCIe, there’s typically additional bits that are transmitted to help with error correction, error detection, and/or clock sync. These additional bits eat up some of the bandwidth, and is referred to generally as just “the overhead”.
For 1 Gigabit Ethernet and 8 Gigabit Fibre Channel as well as SATA I, II, and III, they use 8/10 overhead. Which means for every eight bits of data, an additional two bits are sent.
The difference is who pays for those extra bits. With Ethernet, Ethernet pays. With Fibre Channel and SATA, the user pays.
1 Gigabit Ethernet has a raw transmit rate of 1 gigabit per second. However, the actual transmission rate (baud, the rate at which raw 1s and 0s are transmitted) for Gigabit Ethernet is 1.25 gigabaud. This is to make up for the 8/10 overhead.
SATA and Fibre Channel, however, do not up the baud rate to accommodate for the 8/10 overhead. As such, even though 1,000 Gigabit / 8 bits per byte = 125 MB/s, Gigabit Fibre Channel only provides 100 MB/s. 25 MB/s is eaten up Continue reading

As champions of an open, globally-secure, and trusted Internet, International Data Privacy Day is a big deal around these parts.
But making sure you’re able to share what you want, when you want, should be something the world stands for more than once a year. Every day should be Data Privacy Day.
These days, it feels all too common to hear stories about policy or law enforcement officials trying to create backdoors into technologies like encryption. These backdoors could put our online security at risk.
Just a little over one month ago, Business Insider reported that smart home devices dominated Christmas 2018 sales on Amazon, while the Alexa app, which enables people to control those smart devices, was the most downloaded on Google Play and the Apple App store on Christmas Day.
As the Internet becomes more and more a part of our everyday lives, each of us can take actions to ensure that privacy and security are a top priority.
Let’s come together on Data Privacy Day to celebrate the possibilities an open, globally connected, trusted, and secure Internet brings. Here are ways you can help make it happen where you live:
