Term Definition
G.719

G.719 is an International Telecommunication Union - Telecommunications Unit, or ITU-T, audio codec standard for high quality, moderate bit rate (32 to 128 kbit/s) wideband (20 Hz - 20 kHz audio bandwidth, 48 kHz audio sample rate) audio coding at low computational load. G.719 is optimized for both speech and music.

G.729

G.729 is a codec (compression, decompression), or communications protocol for digital audio data streams. G.729 is widely used for VoiP, or Voice over Internet Protocol applications conserving valuable bandwidth. G.729 operates at 8 kb/s, and includes extensions, featuring transmission rates of 6.4 kbit/s (Annex D, F, H, I, C+) and 11.8 kbit/s (Annex E, G, H, I, C+) offering additional compatibilities, lower and higher speech qualities, respectively.

GARP

Generic Attribute Registration Protocol, or GARP, is an Institute of Electrical and Electronics Engineers (IEEE) protocol to constrain multicast traffic within bridged Ethernet networks.

GbE

Gigabit Ethernet, or GbE, (and also denoted as 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of at least one gigabit per second, as defined by the IEEE 802.3-2008 standard. Half-duplex gigabit links connected through hubs are allowed by the specification but in the marketplace full-duplex with switches are normal. Gigabit Ethernet services operate over fiber optic media, currently at speeds up to 100 Gigabits per second.
