Medienwandel am Beispiel der großen Internetknoten

Von Ralf Keuper

Der Medienwandel bzw. der Stilwandel in der Medienindustrie lässt sich fernab von Reichweitenanalysen und anderen Werkzeugen der Marketing-Esoterik mindestens ebenso so gut an dem Wachstum der Netzwerke und der diversen Internetknoten nachvollziehen, wie das Jonathan Hjembo in Network Growth and Interconnectivity in Global Hubs getan hat. Dabei macht er einige interessante Beobachtungen: 
Intra-European 10G wavelength prices are among the lowest in the world and continue to fall—by as much as 24 percent compounded annually from 2011-2014 on the major Amsterdam-London and Frankfurt-Paris routes. As new submarine cables come online, trans-Pacific prices are beginning to converge with those on the much cheaper trans-Atlantic route. For example, at the end of 2011, the median price of a 10G wavelength between Hong Kong and Los Angeles was nearly nine times that on the London-New York route. Today that gap has narrowed to 3.5x. ...
Content providers such as Google, Facebook, and Microsoft account for the majority of private network usage, and their role in global network development is rapidly increasing. In fact, private networks account for a particularly large share of bandwidth usage on key international routes that interconnect data centers. For example, on the trans-Atlantic route, private network bandwidth eclipsed Internet bandwidth for the first time in history last year. Content providers now create the impetus for the largest network development projects, as their capacity requirements exceed those of the biggest carriers.
