DEFINITION
packets using the network address.
A part of a network; commonly abbreviated "subnet. " When
subnetting is used, the host portion of the IP address is
divided into a subnet and host number. Hosts and routers
use the subnet mask to identify the bits used for the network
and subnet number.
On an Ethernet network, a switch filters frames based on the
MAC address, in a manner similar to a bridge. A switch is more
advanced because it can connect more than two segments.
The SVG2500 uses synchronous timing for upstream data
transmissions. The CMTS broadcasts timing messages that
bandwidth is available. The SVG2500 reserves data bytes
requiring x number of mini-slots. The CMTS replies that it
can receive data at a specified time (synchronized). At the
specified time, the SVG2500 transmits the x-number of data
bytes.
Also known as baud rate. This is a measure of the number of
times per second a signal in a communications channel varies
or makes a transition between states (states being frequencies,
voltage levels or phase angles). Usually measured in symbols
per second (sps).
A de-facto UNIX standard for logging system events.
DEFINITION
Tagged Binary Communication Protocol
Transmission Control Protocol on OSI transport layer four,
provides reliable transport over the network for data transmitted
using IP (network layer three). It is an end-to-end protocol
defining rules and procedures for data exchange between hosts
on top of connectionless IP . TCP uses a timer to track
outstanding packets, checks error in incoming packets, and
retransmits packets if requested.
Transmission Control Protocol/Internet Protocol suite. It provides
standards and rules for data communication between networks
on the Internet. It is the worldwide Internetworking standard
and basic communications protocol of the Internet.
Trivial File Transfer Protocol is a very simple protocol used to
transfer files.
