Welcome to the OSS Line archive

Between 2008 and 2020, OSS Line created and curated useful, actionable information to help telecommunication professionals make decisions about all aspects of their OSS projects and systems. Through the late 2010s, OSS Line steadily grew to become probably the most popular independent blog about the OSS industry and went on to publish the phenomenally popular Guide to Modern OSS.

OSS Line is no longer actively updated. This archive maintains some of the most popular content.

This easy to read 79 page introduction to OSS assumes you know very little about either telecoms or the systems used to manage the network. This revised 2019 edition covers the latest solutions and trends, like orchestration, virtualisation, and machine learning.
