Network Segmentation Efficiencies

May 2, 2012

Kadushin in his book Understanding Social Networks talks about one of the major tasks of network theory and analysis being the need to separate  large networks into smaller segments where the smaller segments cannot overlap with one another and must exist on their own; this is referred to as Blockmodeling.  This theory was utlized in the development of the ARPANET.  For different reasons, the partitioning of data known as packet switching was developed independently in two different countries (the U.S and the U.K) at approximately the same time.  Basically the blockmodelling of small pieces of information would allow the transmission of information more efficiently between computers in the same way that partitioning large social networks results in a more efficent social network. As we look towards Web 3.0 and the need to compartmentalize information, social network theory will likely guide this process.


  1. I really like the phrase packet switching as it describes it literally – systematically swapping chunks of information. What puzzles me a little bit (as a not technical geek), is how much data gets exchanged and the speed at which it does. We recently upgraded our Internet at Shaw in our home to “Extreme Speed”. I’m curious about how this actually works to deliver some information faster than others (of course, we’re only talking about a matter of seconds here). Thanks for your anecdote about your husband’s military communications in class today!

    • Sylvia,
      I’m with you – not sure how packet switching works, but it is a great term!
