AI, LLMs and Networking
Bill Gates recently described the development of AI as a creation as fundamental as the microprocessor, the personal computer, the Internet, and the mobile phone. He is most likely right. OpenAI found that around 80% of the U.S. workforce could have at least 10% of their work tasks affected by the introduction of large language models (LLMs). For those in …
Getting Started with the Rust Programming Language

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 đŸ™‚ 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 …
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 …

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 …
