Speicherbedarf: "Today's bandwidth hog is tomorrow's average user"
Viele Whitepaper sind eine Entäuschung: Da hat man gerade seinen Namen und seine Adressdaten in ein System gefüttert, nur um dann eine verkappte Marketing-Broschüre zu lesen. Hier allerdings ist ein Whitepaper von Cisco, dass sehr lesenswert ist: Exabyte Era. Es geht um Prognosen zum künftigen Anstiegs für die Speicherung und Distribution großer Datemengen, vor allem Videos. Das bereits Anfang 2009 veröffentliche Papier liefert viele konkrete Zahlen und Thesen.
Zitat:
"Today’s “bandwidth hog” is tomorrow’s average user. P2P bandwidth hogs have not elicited much sympathy from the general public, and service providers have been able to institute usage caps without causing much public outcry. However, a household downloading just 3 hours of high- definition content a week would generate at least 27 GB per month, which already exceeds the bandwidth caps of some service providers. Should Internet television become mainstream, 2 hours per day of standard-definition television viewing via the Internet would put a household at 54 GB per month. A household downloading 12 hours of high-definition video per week and 4 hours of standard-definition video viewing per day would easily exceed the most generous of service provider bandwidth caps, usually around 200 GB per month."
