Wired: "Going With The Flow: Google’s Secret Switch To The Next Wave Of Networking"

L'articolo evidenzia molto bene i vantaggi del Software Defined Networking (SDN): - controllo della rete - possibilità di inserire nuovi servizi senza attendere le release software dei vendors (Cisco, Juniper, etc) Questo si traduce in minori investimenti e minori costi operativi secondo i sostenitori dell'SDN (anche se Google stessa non quantifica i risparmi). Nell'Open Networking Foundation partecipano, oltre ai providers riportati nell'articolo, anche gli stessi vendor, attivi nei vari working groups: lo steering committee della Foundation è comunque composto da rappresentati dei soli providers. -- Luca Cicchelli TOP-IX Consortium www.top-ix.org Il giorno 17/apr/2012, alle ore 18.02, J.C.
