The Week in Internet News: AI Ain’t Gonna Steal My Job
AI on the job: Many U.S. residents believe that artificial intelligence will replace some workers over the next decade or so, but it won’t take theirs, according to a story in the New York Times. But it’s not all doom and gloom, because advances in AI and robotics can actually create more jobs, Tim Johnson, CEO of IT staffing firm Mondo, writes in Forbes.
Fixing the IoT: The U.K. government issued a set of guidelines for Internet-of-things device makers to better secure their products. Among the recommendations: Issue regular software updates, get rid of default passwords, and warn customers promptly about vulnerabilities. Ok, so it’s not rocket science, but it seems that some IoT device makers haven’t done some of these things in the past. Some critics also believe the guidelines lack teeth, according to a story in ITpro.
The Blockchain election: The use of Blockchain technologies could help resolve some continuing problems with voting, according to a story by Bitcoin Magazine run on Nasdaq.com. The use of a Blockchain ledger could address the old “hanging chad” problem from the 2000 U.S. election, and it could bring new privacy and security to elections, according to the Continue reading

Applied Networking Research Workshop (ANRW) Call for Papers Due 20 April
We’re excited to share news of the third edition of the Applied Networking Research Workshop (ANRW2018), which will take place in Montreal, Quebec, on Monday, July 16 at the venue of the Internet Engineering Task Force (IETF) 102 meeting. The workshop program already includes some great invited talks and the Call for Papers is open now, with a deadline of 20 April.
ANRW2018 will provide a forum for researchers, vendors, network operators and the Internet standards community to present and discuss emerging results in applied networking research. The workshop will also create a path for academics to transition research back into IETF standards and protocols, and for academics to find inspiration from topics and open problems addressed at the IETF. Accepted short papers will be published in the ACM Digital Library.
ANRW2018 particularly encourages the submission of results that could form the basis for future engineering work in the IETF, that could change operational Internet practices, that can help better specify Internet protocols, or that could influence further research and experimentation in the Internet Research Task Force (IRTF).
If you have some relevant work and would like to join us in Montreal for the workshop and maybe stick Continue reading

Rough Guide to IETF 101: Internet Infrastructure Resilience
In this post of the Internet Society Rough Guide to IETF 101, I’ll focus on important work the IETF is doing that helps improve security and resilience of the Internet infrastructure.
BGP
What happens if an IXP operator begins maintenance work on the switches without ensuring that BGP sessions between the peers have been shut down? A network disruption and outage. A draft now in the RFC editor queue, “Mitigating Negative Impact of Maintenance through BGP Session Culling”, provides guidance to IXP operators on how to avoid such situations by forcefully tearing down the BGP sessions (session culling) affected by the maintenance before the maintenance activities commence. This approach allows BGP speakers to pre-emptively converge onto alternative paths while the lower layer network’s forwarding plane remains fully operational.
Another draft also in the RFC editor queue, “Graceful BGP session shutdown”, addresses issues related to planned maintenance. The procedures described in this document can be applied to reduce or avoid packet loss for outbound and inbound traffic flows initially forwarded along the peering link to be shut down. These procedures trigger, in both Autonomous Systems (AS), rerouting to alternate paths if they exist within the Continue reading
Should You Build or Buy an Automation Solution?
One of the most important aspects of the introductory part of my Building Network Automation Solutions online course is the question should I buy a solution or build my own?
I already described the arguments against buying a reassuringly-expensive single-blob-of-complexity solution from a $vendor, but what about using point tools?

Starting next weekend, the Internet Engineering Task Force will be in London for IETF 101, where about 1000 engineers will discuss open internet standards and protocols. The week begins on Saturday, 17 March, with a Hackathon and Code Sprint. The IETF meeting itself begins on Sunday and goes through Friday.
As usual, we’ll write our ‘Rough Guide to the IETF’ blog posts on topics of mutual interest to both the IETF and the Internet Society:
- Overview of ISOC @ IETF
- Routing Infrastructure Security Resilience
- Internet of Things
- IPv6
- DNSSEC, DANE and DNS Security
- Identity, Privacy, and Encryption
- Community Networks

Worth Reading: How to Talk to a C-Level Executive
Ever wondered who manages to produce deja-moo like this one and why they’d do it?
We unveiled a vision to create an intuitive system that anticipates actions, stops security threats in their tracks, and continues to evolve and learn. It will help businesses to unlock new opportunities and solve previously unsolvable challenges in an era of increasing connectivity and distributed technology.
As Erik Dietrich explains in his blog post, it’s usually nothing more than a lame attempt to pretend there are some clothes hanging on the emperor.
Just in case you’re interested: we discussed the state of Intent-Based Majesty’s wardrobe in Network Automation Use Cases webinar.
Disjoint Path Routing and LP
We are all well aware about the problem space of finding the Shortest Path and use of Dijsktra algorithm. In this blog, we will take a peek at the problem space for Disjoint Path routing, see how it can be reduced to the optimization problem and a few algorithms in that space. So first, let’s […]CGN, IPv6 and fighting online crime…
Carrier Grade NAT (CGN) is commonly used by network operators as a way of ekeing out the limited supply of public IPv4 addresses. This is where private IPv4 addresses are allocated to end customers, who in turn also use private IPv4 address ranges on their own Local Area Networks, which means there can be multiple layers of Network Address Translation (NAT) before traffic reaches the publicly addressed Internet.
Whilst CGN offers something of a technical solution to the shortage of public IPv4 addresses, it presents a number of problems for investigating and solving online crime. A CGN environment means that many hundreds of users can be sharing a single public IPv4 address, so that when a crime is committed, tracing the perpetrator is very difficult. Furthermore, sometimes action needs to be taken against a public IPv4 address that’s the origin of particular problems, but this then penalises many hundreds or even thousands of innocent users who may also be sharing that IP address.
Europol, the European Union Agency for Law Enforcement Cooperation, has identified that CGN is an impediment to investigating online crime, and is therefore consulting the Internet community on how network operators can be encouraged to deploy IPv6.

U.S. SEC Targets Unregulated Cryptocurrency Exchanges
The U.S. Securities and Exchange Commission could soon crack down on unregulated cryptocurrency trading platforms after the agency sent a strongly worded warning to them this week.
The SEC warned that unregulated online trading platforms may be misleading investors by calling themselves “exchanges,” which implies federal oversight. An SEC-related securities exchange, among other safeguards, has rules designed to prevent fraud and other manipulative practices, the SEC said in an advisory issued Wednesday.
The SEC advisory served as much as a warning to investors using cryptocurrency trading platforms as to the platforms themselves.
“The SEC staff has concerns that many online trading platforms appear to investors as SEC-registered and regulated marketplaces when they are not,” the advisory said. “Many platforms refer to themselves as ‘exchanges,’ which can give the misimpression to investors that they are regulated or meet the regulatory standards of a national securities exchange.”
The SEC does not review the trading protocols used by unregulated trading platforms, it said. “Although some of these platforms claim to use strict standards to pick only high-quality digital assets to trade, the SEC does not review these standards or the digital assets that the platforms select, and the so-called standards should Continue reading
