Juniper QFX5110 | VMware NSX ESG | BGP Route Policy

This post follows on from a previous article which detailed how to establish a BGP peering session between Juniper QFX and VMware NSX Edge Gateway. This time we’ll take a look at how to configure BGP route policy and BGP filters.

Overview

When working with BGP, it’s important to consider how BGP routes are imported and exported. In certain scenarios, you may find that the default BGP import and export behaviour is sufficient. But more often than not, you will want to implement an import and export policy in order to control how traffic flows through your network. Here’s a quick reminder of the default behaviours:-

Default Import Policy

  • Accept all BGP routes learned from configured BGP neighbors and import them into the relevant routing table.

Default Export Policy

  • Do not advertise routes learned from IBGP neighbors to any other configured IBGP neighbor. Unless acting as a route reflector.
  • Readvertise all active BGP routes to all configured BGP neighbors.

In the following scenario, we’re going to configure BGP import and export policies on Juniper QFX Switches and VMware NSX Edge Gateways. The Juniper QFX switches will be configured to export a default route (0.0.0.0/0) towards the Continue reading

Gilad Gressel On Why You Should Watch His Newest Course: Deep Learning With Python

Hi, my name is Gilad Gressel and I’d like to tell you about my new course: Deep Learning with Python.

Deep learning is an old technology that has recently been sweeping through the field of machine learning and artificial intelligence. Deep learning powers many of the cutting edge technologies that appear to be “magic” in the world today. Voice recognition, image detection, facial recognition, AI game playing agents (Dota, Chess, and Go), all of these are examples of deep learning in action.

Why Would You Be Interested in Deep Learning?

You might be interested in studying deep learning simply because you want to know what the “magic” is, what the hype is all about. That’s a fine reason to take this course, but I urge you to dig a bit deeper. If you have ever stared at a bunch of data and known “there is a pattern here, but I can’t find it,” then this is the course for you!

About The Course

In this course you will learn what is going on in a deep learning program, what it can do and what it’s limitations are. If you are wondering if you can apply deep learning to your field Continue reading

New Case Study: The Impact of a Community Network on Improving Education in Pakistan

Two years ago, the Internet Society and COMSATS Internet Services, a local Internet service provider in Pakistan, ventured into Chak-5 Faiz, a rural village in the Punjab province, 25 kilometres from the city of Multan. At that time, some of the villagers had to walk two kilometres to access the Internet. Little did we know, tucked away in this village was a hidden treasure at the Government Girls High School in Chak-5 Faiz. At the school, we discovered a fully-equipped computer lab with nework facilities that was locked up and unused. It was unused because no one knew how to set up and use the equipment in the lab.
As part of a pilot initiative of the Wireless for Communities Programme, we worked with the local community to establish an Internet connection at the school, and there has been no turning back since. Teachers and students have been making full use of the Internet by accessing information, developing their digital literacy and finding innovative ways to use the Internet. The school connected with Tele Taleem, a local organisation based in Islamabad that specialises in online education, to improve the quality of teaching as well as students’ learning experience.

Roughtime: Securing Time with Digital Signatures

Roughtime: Securing Time with Digital Signatures
Roughtime: Securing Time with Digital Signatures

When you visit a secure website, it offers you a TLS certificate that asserts its identity. Every certificate has an expiration date, and when it’s passed due, it is no longer valid. The idea is almost as old as the web itself: limiting the lifetime of certificates is meant to reduce the risk in case a TLS server’s secret key is compromised.

Certificates aren’t the only cryptographic artifacts that expire. When you visit a site protected by Cloudflare, we also tell you whether its certificate has been revoked (see our blog post on OCSP stapling) — for example, due to the secret key being compromised — and this value (a so-called OCSP staple) has an expiration date, too.

Thus, to determine if a certificate is valid and hasn’t been revoked, your system needs to know the current time. Indeed, time is crucial for the security of TLS and myriad other protocols. To help keep clocks in sync, we are announcing a free, high-availability, and low-latency authenticated time service called Roughtime, available at roughtime.cloudlare.com on port 2002.

Time is tricky

It may surprise you to learn that, in practice, clients’ clocks are heavily skewed. A recent study of Continue reading

Smart or Dumb NICs on Software Gone Wild

Hardware vendors are always making their silicon more complex and feature-rich. Is that a great idea or a disaster waiting to happen? We asked Luke Gorrie, the lead developer of Snabb Switch (an open-source user-land virtual switch written in Lua) about his opinions on the topic.

TL&DL version: Give me a dumb NIC, software can do everything else.

Same-different problems strain convolutional neural networks

Same-different problems strain convolutional neural networks Ricci et al., arXiv 2018

Since we’ve been looking at the idea of adding structured representations and relational reasoning to deep learning systems, I thought it would be interesting to finish off the week with an example of a problem that seems to require it: detecting whether objects in a scene are the same or different.

This image containing a flute was correctly classified by a CNN trained on millions of photographs. On ImageNet the network even surpassed the accuracy of a human observer.

This image contains two shapes that are the same, a relationship that is immediately obvious to a human observer. “Yet, the CNN failed to learn this relation even after seeing millions of training examples.”

The above is an example of a same-different (SD) visual relation problem (output whether the objects in the scene are the same, or different). Spatial relation (SR) problems ask whether objects follow a certain spatial relation, e.g. in a line, horizontally stacked, vertically stacked, and so on. For example:

The synthetic visual reasoning test (SVRT) contains a collection of 23 binary classification problems along these lines. In each case opposing classes differ Continue reading

Business Solutions at AnsibleFest

AF-Business-Solutions-Blog

I’ve always enjoyed listening to how customers are solving their business challenges using Red Hat Ansible Automation. From the simple to the uniquely creative solutions, they’re always fun to hear. So every time AnsibleFest comes around, I get especially excited knowing that I’ll have the chance to hear far more than one or two stories.

This year’s AnsibleFest in Austin is expected to be the biggest ever. To cater for the many different interests of attendees, we’ve created six specific tracks with curated content sure to interest. I’ve managed to “bag” the Business Solutions track, which will contain ten talks in total.

Sifting through the hundreds of submissions (the job gets harder every year!) I’ve picked out three talks which I’m really looking forward to listening to.

1. Upgrading the backend database of a £3 billion business website on a Friday afternoon

However that panned out, it’s sure to be a great story! I’m grabbing some popcorn for this one :)

2. Using Ansible to Satisfy Compliance Controls

Security automation is a big topic these days, and the security community has come to realise the power in Ansible to help them get things done. I’ve lost count of the Continue reading
