Since its inception, Ethernet has enjoyed remarkable growth. Today, hundreds of millions of Ethernet switch ports ship every year. Initially intended to connect computers on local networks, Ethernet applications now range from global telecommunications and supercomputing to industrial automation and avionics. To meet the needs of these diverse applications, Ethernet standards have been defined for a wide range of speeds and transmission media.
