What is GigE?
GigE is the third generation of Ethernet, the dominant global LAN standard protocol for transmitting IP (Internet Protocol) packets (data, video, voice) over standard IP networks. The Ethernet standard defines four data rates: Ethernet (10 Mb/s), Fast Ethernet (100 Mb/s), Gigabit Ethernet, or GigE (1000 Mb/s or 1 Gb/s), and 10GigE (10,000 Mb/s or 10 Gb/s). At all speeds, Ethernet’s underlying packet processing and transmission protocols are the same, allowing multi-rate Ethernet networks to inter-work seamlessly.
