GFP
encapsulation
Generic Framing Procedure (GFP) is a generic mapping technology. It
can group variable-length or fixed-length data for unified adaption,
making data services transmitted through multiple high-speed physical
transmission channels.
Ground cable
The cable to connect the device to ground, usually a yellow/green
coaxial cable. Connecting the grounding cable properly is an important
guarantee to lightning protection, anti-electric shock, and anti-
interference.
H
Half duplex
In a communication link, both parties can receive or send data at a time.

Institute of
Electrical and
Electronics
Engineers
(IEEE)
A professional society serving electrical engineers through its
publications, conferences, and standards development activities. The
body responsible for the Ethernet 802.3 and wireless LAN 802.11
specifications.
Internet
Assigned
Numbers
Authority
(IANA)
The organization operated under the IAB. IANA delegates authority for
IP address-space allocation and domain-name assignment to the NIC and
other organizations. IANA also maintains a database of assigned
protocol identifiers used in the TCP/IP suite, including autonomous
system numbers.
Internet
Engineering
Task Force
(IETF)
A worldwide organization of individuals interested in networking and
the Internet. Managed by the Internet Engineering Steering Group
(IESG), the IETF is charged with studying technical problems facing the
Internet and proposing solutions to the Internet Architecture Board
(IAB). The work of the IETF is carried out by various working groups
that concentrate on specific topics, such as routing and security. The
IETF is the publisher of the specifications that led to the TCP/IP
protocol standard.

Link
Aggregation
With link aggregation, multiple physical Ethernet interfaces are
combined to form a logical aggregation group. Multiple physical links in
one aggregation group are taken as a logical link. Link aggregation helps
share traffic among member interfaces in an aggregation group. In
addition to effectively improving the reliability on links between
devices, link aggregation can help gain greater bandwidth without
upgrading hardware.
Link
Aggregation
Control
Protocol
A protocol used for realizing link dynamic aggregation. The LACPDU is
used to exchange information with the peer device.
