SDxCentral Weekly Wrap for Oct. 11, 2019: One analyst cites climate change for AT&T's $2...
In my last post I showed you how you can use plain old BGP to distribute labels and create LSPs. While sort of interesting to see – it wasn’t super handy all by itself. In this post, we’re going to try and layer on MPLS VPNs to the same setup and show you how that might work. So let’s dig right in. I’m assuming that you’ve read the last post and that we’re picking up where things left off there.
Note: There are no pretty diagrams here so if you’re looking for some context on the lab we’re using go back and checkout the last post.
The first thing we want to do is put our client subnets into VRFs or routing-instances in Juniper parlance. Let’s do that on each tail router….
set routing-instances customer1 instance-type vrf set routing-instances customer1 interface ge-0/0/0.0 set routing-instances customer1 route-distinguisher 1:1 set routing-instances customer1 vrf-target target:1:1 set routing-instances customer1 vrf-table-label
set routing-instances customer1 instance-type vrf set routing-instances customer1 interface ge-0/0/1.0 set routing-instances customer1 route-distinguisher 1:1 set routing-instances customer1 vrf-target target:1:1 set routing-instances customer1 vrf-table-label
So nothing fancy here – we’re just creating a routing instance, assigning an RT/RD, Continue reading
The recent meeting of the United Nations General Assembly (UNGA) was notable because of the attention it paid to the climate of the planet Earth. A different set of meetings around the UNGA was about another climate: the one of fear, anger, and violence swirling about the Internet.
It was only last March that a man (there is only one accused) shot dozens of people in a pair of attacks on Muslims at prayer. The shooter streamed the first 17 minutes of his attacks using Facebook Live. The use of an Internet service in this event, combined with general concern about how Internet services are being used for terrorism and violent extremism, resulted in the Christchurch Call.
There is some reason to be optimistic about the Christchurch Call. Rarely have governments worked so decisively or quickly, together, to take on a global social issue. At a side meeting in New York at UNGA, some 30-odd additional countries signed the Call; more than 50 countries have signed on. New Zealand has led this while insisting that governments cannot tackle the issue alone, and has tried to involve everyone – through an Advisory Network – in decisions that are bound to affect Continue reading
Grouping the features needed in a networking stack in bunch of layered modules is a great idea, but unfortunately it turns out that you could place a number of important features like error recovery, retransmission and flow control in a number of different layers, from data link layer dealing with individual network segments to transport layer dealing with reliable end-to-end transmissions.
So where should we put those modules? As always, the correct answer is it depends, in this particular case on transmission reliability, latency, and cost of bandwidth. You’ll find more details in the Retransmissions and Flow Control part of How Networks Really Work webinar.

Learning a unified embedding for visual search at Pinterest Zhai et al., KDD’19
Last time out we looked at some great lessons from Airbnb as they introduced deep learning into their search system. Today’s paper choice highlights an organisation that has been deploying multiple deep learning models in search (visual search) for a while: Pinterest.
With over 600 million visual searches per month and growing, visual search is one of the fastest growing products at Pinterest and of increasing importance.
Visual search is pretty fundamental to the Pinterest experience. The paper focuses on three search-based products: Flashlight, Lens, and Shop-the-Look.
In Flashlight search the search query is a source image either from Pinterest or the web, and the search results are relevant pins. In Lens the search query is a photograph taken by the user with their camera, and the search results are relevant pins. In Shop-the-Look the search query is a source image from Pinterest or the web, and the results are products which match items in the image.
Models are like microservices in one sense: it seems that they have a tendency to proliferate within organisations once they start to take hold! (Aside, I wonder if there’s Continue reading
Beneath the veneer of glass and concrete, this is a city of surprises and many faces. On 3rd October 2019, we brought together a group of leaders from across a number of industries to connect in Central Jakarta, Indonesia.
The habit of sharing stories at the lunch table, exchanging ideas, and listening to ideas from the different viewpoints of people from all tiers, paying first-hand attention to all input from customers, and listening to the dreams of some of life’s warriors may sound simple but it is a source of inspiration and encouragement in helping the cyberspace community in this region.
And our new data center in Jakarta extends our Asia Pacific network to 64 cities, and our global network to 194 cities.
Right on time, Kate Fleming extended a warm welcome to our all our Indonesia guests. "We were especially appreciative of the investment of your time that you made coming to join us."
Kate, is the Head of Customer Success for APAC. Australian-born, Kate spent the past 5 years living in Malaysia and Singapore. She leads a team of Customer Success Managers in Singapore. The Customer Success team is dispersed across multiple offices and time Continue reading

We’re continuing our celebration of Women in Tech Week with another profile of one of many of the amazing women who make a tremendous impact at Docker – this week, and every week – helping developers build modern apps.
I work as a data engineer – building and maintaining data pipelines and delivery tools for the entire company.
2 years.
Not quite! As a teenager, I wanted to become a cryptographer and spent most of my time in undergrad and grad school on research in privacy and security. I eventually realized I liked working with data and was pretty good at dealing with databases, which pushed me into my current role.
Become acquainted with the entire data journey and try to pick up one tool or language for each phase. For example, you may choose to use Python to fetch and transform data from an API and load it Continue reading

Point To Point In The Datacenter With Andy Bechtolsheim was written by Timothy Prickett Morgan at The Next Platform.
You may have noticed our technical documentation has a new look and feel. The reason? We recently migrated to a new platform, Hugo, a really fast static site generator. All our written content is formatted in Markdown and the source code is stored in a public GitHub repository. When we merge a release branch into the master branch, the site automatically gets rebuilt, which takes about 5 minutes from provisioning to deploying the new build, so we can quickly update the site when we come across an issue.
What does this all mean for you? We encourage you to participate if you have the opportunity and desire — and we certainly welcome your pull requests! Feel free to update anything you see that is incorrect or that could be written more clearly. If your time is limited, you can always file a bug against the docs too.
We also accept your original content! If you have an automation solution or a unique Cumulus Linux deployment you’d like to share, feel free to write about it and we’ll host it in the Network Solutions section of the Cumulus Linux user guide. You can read our contributor guide for guidelines on Continue reading
