vlog. Episode 5. NetLdn: Networking for Networkers
Hello my friends,
It is always cool to talk about various network technologies with the engineers from industry, and to meet some awesome chaps. I had a pleasure to attend such an event in London in the last months. Learn my findings on that.
In this episode, together with James Bensley and Richard Patterson from Sky we discuss the the NetLdn event series. The event, where you can discuss network technoligies with the peers and, perhaps, make some friends.

REST API 3. Basics cheat sheet (Ansible, Bash, Postman, and Python) for PATCH/PUT using NetBox
Hello my friend,
This is the third and the last article about REST API basics. In the previous articles, you have learned how to collect information and create/delete new entries. Today you will learn how to modify existing entries.

Disclaimer
This article is a continuation of the two previous: GET and POST/DELETE. You should start with that to get the full picture.
What are we going to test?
You will learn how to use two requests:
- PATCH for modifying information for existing entries
- PUT for modifying information for existing entries
As you might remember, the interaction with the REST API is described by CRUD model, what stands for Create, Read, Update, and Delete. In this concept, Update operation is represented by PATCH and PUT HTTP methods. Later in this article you will figure out what is the difference between PATCH and PUT. It is significant.
To put the context, we will Continue reading
REST API 2. Basics cheat sheet (Ansible, Bash, Postman, and Python) for POST/DELETE using NetBox and Docker as examples
Hello my friend,
In the previous blogpost, we started the exciting journey in the world of REST API, where you have learned how to collect the information using GET method. Today you will learn how to create the objects using POST method and remove them using DELETE.

To put the context, Digital Ocean NetBox and Docker are the applications, which we will manage over the REST API.

Brief description
The REST API was already extensively used in my previous articles about the Data Centre Fabric project such as NetBox integration with the Infrastructure Enabler Stack, monitoring of the network infrastructure using Telegraf/InfluxDB/Grafana or closed-loop automation with Kapacitor. Nevertheless, we haven’t discussed how to work with the REST API itself.
In terms of using the Web applications, there are four main action types forming CRUD abbreviation:
- C – CREATE is an action type, which creates the entry within the application database.
- R – READ is an action type, which extract the existing information out of the Continue reading
vlog. Episode 4. Discussion about RPKI OV (protecting routing in Internet)

DC/SP. Part 13/8. Real-time data analytics and closed-loop automation with InfluxData Kapacitor for the Data Centre Fabric
Hello my friend,
This article is kind of a special one for me. It doesn’t mean that everything I have written before has a little sense. Everything what I have written about the Data Centre Fabric project was steps towards fully automated data centre operation, and today we make a final step towards the closed-loop automation based using the real-time data analytics by InfluxData Kapacitor.

Brief description
According to the official website, InfluxData Kapacitor is alerting system following publish-subscribe design pattern, which supports both steam and batch data processing. If we translate it from the geeks’ language, it means that Kapacitor can subscribe to a certain to topics in the data producer (e.g., time series database – InfluxDB or collector – Telegraf) and start getting information out of it:
- Steam processing means that all the information coming to the subscribed Continue reading
Three years on air
Hello my friend,
Three years ago, on the 5th June 2016, we have posted the first article about Nokia SR OS/ Cisco IOS XR interop. We can dispute, if it was long ago or not, but what we can’t dispute the amount of information shared with you since that time on various network and automation topics!

Over these three years we have posted 75 (seventy five!) articles about the design, configuration and implementation of the multivendor networks with Nokia SR OS, Cisco IOS XR, Arista EOS and Cumulus Linux. Out of that 75, the 21 articles were written in this third year. Thanks to the blog activity we were awarded as the CiscoChampion 2019 as a top tech influencers worldwide.

The last year was a kind of breakthrough, not only based on the topics we were covering, about which we’ll Continue reading
