ギガビット・イーサネット
The adoption of 10 Gigabit Ethernet has been more gradual than previous revisions of Ethernet: in 2007, one million 10GbE ports were shipped, in 2009 two million ports were shipped, and in 2010 over three million ports were shipped, with an estimated nine million ports in 2011. , although the price per gigabit of bandwidth for 10 Gigabit Ethernet was about one-third compared to Gigabit Ethernet, the price per port of 10 Gigabit Ethernet still hindered more widespread adoption.
