Transmission Control Protocol/Internet Protocol (TCP/IP)
Protocol suite that includes TCP as the primary transport protocol, and IP
as the network layer protocol.
User Datagram Protocol (UDP)
UDP
provides a datagram mode for packet-switched communications. It
uses IP as the underlying transport mechanism to provide access to IP-like
services. UDP packets are delivered just like IP packets – connection-less
datagrams that may be discarded before reaching their targets. UDP is
useful when TCP would be too complex, too slow, or just unnecessary.
UTP
Unshielded twisted-pair cable.
Very high data rate Digital Subscriber Line (VDSL)
A family of digital telecommunications protocols designed to allow high
speed data communication at data rates from below 1 Mbps to 52.8 Mbps
with corresponding maximum reach ranging from 4500 feet to 1000 feet
using 24 gauge twisted pair cable over the existing copper telephone lines
between end-users and service providers.
Very high data rate Digital Subscriber Line 2 (VDSL2)
VDSL2 as defined in ITU-T Recommendation G.993.2 is an enhancement
to the first VDSL standard (G.993.1). It supports transmission at a
bi-directional net data rate (the sum of upstream and downstream rates) of
up to 200 Mbps on twisted pair cables using a bandwidth of up to 30 MHz.
VDSL2 includes many enhancements, one of which is the addition of the
US0 band and methods to train echo cancellers and time domain
equalizers.
