ChatGPT your Project Docs
I mentioned in my last post that I would start updating practical use cases for generative AI. The first example use case is your project documentation. As software engineers, we spend days of our lives writing project docs. The reality is that people learn and consume data differently. Overly detailed docs may cause some people’s eyes to glaze over while …
Getting Started with the Rust Programming Language
A programming language that has begun picking up momentum in the community lately is Rust. This is a guide aimed at helping folks get started with the Rust Programming Language. Rust has been around for a while with a stable v1.0 shipping in 2015. Rust initially came from Mozilla who maintain the multi-million line C++ codebase in Firefox that has …
GoBGP – A Control Plane Evolving Software Networking
If I have talked to you over the past year or two about networking, odds are I have mentioned a project to you called GoBGP. If we have spoken a lot, you are probably sick of me talking to you about GoBGP 🙂 There is a reason, it’s because GoBGP is a missing link in networking that has been for …
Building Network Tools using Docker
I am going to start pushing out an app every month that fixes some problem in networking. In this case I hacked it up over the past couple of weekends, but other times it will just be me using someones open source awesomeness and demoing it. First some thoughts on where we are in the wild world of networking to …
Docker Command One Liners
I love the code snippets, it’s how I learn any syntax by rolling up the sleeves, hacking and breaking while taking notes along the way. It’s probably not the most efficient but the muscle memory is how I learn. Here is a list of one liners from my notes in no particular order (even though I tried to in a …
Installing Golang IDE Support in Intellij
I have always preferred Intellij Community Edition IDE for Java, Bash, Python, Node and anything else I have needed, including recently C/C++ which is pretty slick. The plus is I can hang on to key-mappings, syntax color and general workflow all in a ubiquitous dev environment. There are some good IDE options for Go and of course support for the …
Golang for Network Ops
I get asked quite often where the traditional network engineer / network ops should start if they want to broaden their horizons with better code hacking skills or they have spent the last 20 years using Perl scripts or more recently Python and need a change. The answer is easy, Golang. At Socketplane, we all ditched the past couple of …
Updated DevStack OpenDaylight VM Image for OpenStack IceHouse
Here is an updated Fedora 20 image for building OpenStack Icehouse and OpenDaylight. ODL is now merged into the upcoming OpenStack Icehouse release so now you can install ODL directly from OpenStack trunk. The updated image comes from Kyle Mestery who was primarily responsible for getting the OpenStack/OpenDaylight merge and navigating the process. Thanks also to Andrew Grimberg from the …
OpenDaylight OpenStack Integration with DevStack on Fedora
The following is a walk through of the OVSDB project within OpenDaylight for OpenStack integration. There are a couple of bugs so it is not for the faint of heart. It is intended for those looking to get their development environment up and running. We will have videos and what not walking through the installation and code reviews of the …
Getting Started With OVSDB
OVSDB (Open vSwtich Database) is a management protocol used to manipulate the configuration of Open vSwitches and more recently vendors have begun implementing OVSDB in their Ethernet switches firmware. Some of those vendor data plane implementations are already running OVS under the hood so the implementation should be relatively painless. A project I am involved in developing is the OVSDB …
OpenDaylight Maven and OSGI Dev Notes
Prior to OpenDaylight I had only used the ODGI framework with David Ericson’s Beacon contorller. I wanted to dump some of my notes from code hacking over the past couple of weeks. Most of the time has been spent getting used to OSGI and Maven. After the Maven and OSGI overviews, I list my dev notes for setting OSGI log …
Importing OpenDaylight Into Eclipse
This is a quick video for importing OpenDaylight into Eclipse for development. You need to build OpenDaylight with Maven prior to importing it into Eclipse. Once you build ODL from the CLI, you can either run it from there for learning OpenFlow or getting to know the OpenDaylight controller or go on to importing the controller into Eclipse. For those …
SDN OpenFlow Policy Abstractions
SDN OpenFlow Policy Abstractions : Abstraction layers are a fundamental principle in computer science. It is a core pillar in creating efficiencies through layered, modular scale. Proper abstraction layers are also where the networking train came off the tracks. Network operators program network devices using proprietary APIs one device at a time. In today’s networks, when we push policy to …
Floodlight OpenFlow Controller: Using the Static Flow Entry Pusher
Floodlight OpenFlow Controller: Using the Static Flow Entry Pusher: The first post in this tutorial can be found at Tutorial to Build a FloodLight SDN OpenFlow Controller . For those looking to do things with early SDN / OpenFlow controllers this post may be of some use to kickstart your efforts. I am posting a Java class below that Cory Fowler …
Tutorial to Build a FloodLight SDN OpenFlow Controller Module
This how-to is a tutorial to build a FloodLight SDN OpenFlow controller module in Java using the open source OpenFlow controller FloodLight that BigSwitch open sourced to the community. The installation and class creation is documented on the FloodLight Wiki. I am adding a screencast of the installation for those who get stuck on any steps. This is just how …
