DEFINITION
An OSI layer 2 networking device that connects two LANs using
similar protocols. It filters frames based on the MAC address
to reduce the amount of traffic. A bridge can be placed
between two groups of hosts that communicate a lot
together, but not so much with the hosts in the other group.
The bridge examines the destination of each packet to
determine whether to transmit it to the other side. See also
switch.
High bandwidth network technology that multiplexes
multiple, independent carriers to carry voice, video, data, and
other interactive services over a single cable. A communications
medium that can transmit a relatively large amount of data in a
given time period. A frequently used synonym for cable TV
that can describe any technology capable of delivering multiple
channels and services.
Simultaneous transmission to multiple network devices; a
protocol mechanism supporting group and universal
addressing. See also multicast and unicast.
DEFINITION
A project of CableLabs and technology suppliers to develop
interface specifications for extending high-quality, cable-based
services to home network devices. It addresses issues such as
device interoperability, QoS, and network management.
CableHome will enable cable service providers to offer more
services over HFC. It will improve consumer convenience by
providing cable-delivered services throughout the home.
A research consortium that defines the interface
requirements for cable modems and acknowledges that tested
equipment complies with DOCSIS.
A device installed at a subscriber location to provide data
communications over an HFC network. Unless otherwise
specified, all references to "cable modem" in this
documentation refer to DOCSIS or Euro-DOCSIS cable
modems only.
File containing operational parameters that a cable modem or
gateway downloads from the Internet Service provider TFTP
server during registration.
