CAT-6
Category 6 cable. A cable standard for
gigabit Ethernet and other network proto-
cols that are backward-compatible with the
Category 5/5e and Category 3 cable
standards. Compared with
and
CAT-5e, CAT-6 features more stringent
specifications for crosstalk and system
noise. The cable standard provides perfor-
mance of up to 250MHz and is suitable for
10BASE-T, 100BASE-TX (Fast Ethernet),
1000BASE-T/1000BASE-TX (Gigabit
Ethernet), and 10GBASE-T (10GbE).
Category 6 cable has a reduced maximum
length when used for 10GBASE-T;
Category 6a cable, or Augmented
Category 6, is characterized to 500MHz
and has improved alien crosstalk charac-
teristics, allowing 10GBASE-T to be run for
the same distance as previous protocols.
Category 6 cable can be identified by the
printing on the side of the cable sheath.
challenge-handshake authentication
protocol
See
CHAP
Challenge-handshake authentication
protocol (CHAP) is used for remote logon,
usually between a client and server or a
Web browser and Web server. A
challenge/response is a security mecha-
nism for verifying the identity of a person
or process without revealing a secret
password that is shared by the two
entities. Also referred to as a
three-way
handshake

parameters.

Converged Network Adapter
Converged Network Adapters support
both data networking (TCP/IP) and
storage networking (
) traffic
on a single I/O adapter using two new
technologies:

DCB
Data center bridging. Provides enhance-
ments to existing 802.1 bridge specifica-
tions to satisfy the requirements of
protocols and applications in the data
center. Because existing high-performance
data centers typically comprise multiple
application-specific networks that run on
different link layer technologies (Fibre
Channel for storage and Ethernet for
network management and LAN connec-
tivity), DCB enables 802.1 bridges to be
used for the deployment of a converged
network where all applications can be run
over a single physical infrastructure.
