Rough Guide to IETF 101: Back to London

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.

Drilling Down Into Ethernet Switch Trends

Of the three pillars of the datacenter – compute, storage, and networking – the one that consistently still has some margins and yet does not dominate the overall system budget is networking. While these elements affect each other, they are still largely standalone realms, with their own specialized devices and suppliers. And so it is important to know the trends in the technologies.

Until fairly recently, the box counters like IDC and Gartner have been pretty secretive about the data they have about the networking business. But IDC has been gradually giving a little more flavor than just saying Cisco …

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

Internet Intelligence, Now Available In The Oracle Cloud Infrastructure Console

The Oracle Cloud Infrastructure (OCI) team is proud of the data centers and network we are building for the next generation of cloud users and, in the spirit of transparency, we want to share with our users tools to better evaluate and measure the performance they will experience on our cloud. Today, we are pleased to announce two new network tools available in the Console to help you measure and analyze network performance.

OCI Market Performance is an interactive visualization tool that displays network performance metrics from OCI regions to cities around the globe.  Performance is measured over time to a carefully curated set of endpoint IP addresses within the top providers in each market, providing the user with aggregated performance data for markets and providers over the last day, week, month or three months. This latency data from our Phoenix, Ashburn, and Frankfurt regions can help you predict and manage network performance.  We will be adding metrics for more of our regions as they come online (including our twelve recently announced regional data centers).

OCI Market Performance can also assist in planning for growth, as you extend your footprint into new global markets.  For FastConnect customers, this tool can help to predict performance between an OCI region and a specific Continue reading

How to check your network connections on Linux

The ip command has a lot to tell you about the configuration and state of your network connections, but what do all those words and numbers mean? Let’s take a deep dive in and see what all the displayed values are trying to tell you.When you use the ip a (or ip addr) command to get information on all the network interfaces on your system, you're going to see something like this:$ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:1e:4f:c8:43:fc brd ff:ff:ff:ff:ff:ff inet 192.168.0.24/24 brd 192.168.0.255 scope global dynamic enp0s25 valid_lft 57295sec preferred_lft 57295sec inet6 fe80::2c8e:1de0:a862:14fd/64 scope link valid_lft forever preferred_lft forever The two interfaces on this system — the loopback (lo) and network (enp0s25) — are displayed along with a lot of stats. The "lo" interface is clearly the loopback. We can see the loopback IPv4 address (127.0.0.1) and the loopback Continue reading

Ansible for Extreme Devices

Here’s something I’ve been working on recently: Ansible modules for Extreme SLX switches & routers. Ansible is a popular automation framework, and with good reason: it has a low barrier to entry. Time to usefulness is short. But you need device-specific modules to work with networking devices. Finally we have some modules for SLX. Read on for how to use them.

This blog is not an intro to Ansible in general. There’s plenty of good intros out there. This is specifically about demonstrating Ansible with SLX switches.

Background

Ansible is an agent-less configuration management system. It uses “playbooks”, written in YAML, to define desired configuration state. “modules” written in Python translate this into whatever is needed to configure the system, application, database or network device.

Ansible has been making great strides in adding network automation capabilities. But we haven’t had any modules for working with ~Brocade~ Extreme devices. That is now changing.

PaulQuack has contributed MLXe (Ironware) modules, which will go GA in Ansible 2.5 (due for release in March 2018). And I’ve been working on modules for the SLX, with my colleagues. These have not yet been merged upstream, but it’s Open Source, so you can grab Continue reading

Stuff The Internet Says On Scalability For March 9th, 2018

Hey, it's HighScalability time:

 

The largest simulation of the cosmos ever run finally produces a universe similar to our own. All it required was 24,000 processors, more than two months, and it produced 500 terabytes of data.

 

If you like this sort of Stuff then please support me on Patreon. And I'd appreciate if you would recommend my new book—Explain the Cloud Like I'm 10—to anyone who needs to understand the cloud (who doesn't?). I think they'll learn a lot, even if they're already familiar with the basics.
