D-Link DGS-3324SRi Intelligent Stackable Gigabit Ethernet Switch

forwarding
The process of sending a packet toward its destination by an internetworking device.
full duplex
A system that allows packets to be transmitted and received at the same time and, in effect,
doubles the potential throughput of a link.
half duplex
A system that allows packets to be transmitted and received, but not at the same time. Contrast
with
full duplex
.
IP address
Internet Protocol address. A unique identifier for a device attached to a network using TCP/IP.
The address is written as four octets separated with full-stops (periods), and is made up of a network section,
an optional subnet section and a host section.
IPX
Internetwork Packet Exchange. A protocol allowing communication in a NetWare network.
LAN
Local Area Network. A network of connected computing resources (such as PCs, printers, servers)
covering a relatively small geographic area (usually not larger than a floor or building). Characterized by
high data rates and low error rates.
latency
The delay between the time a device receives a packet and the time the packet is forwarded out of
the destination port.
line speed
See
baud rate
.
main port
The port in a resilient link that carries data traffic in normal operating conditions.
MDI
Medium Dependent Interface. An Ethernet port connection where the transmitter of one device is
connected to the receiver of another device.
MDI-X
Medium Dependent Interface Cross-over. An Ethernet port connection where the internal transmit
and receive lines are crossed.
MIB
Management Information Base. Stores a device’s management characteristics and parameters. MIBs
are used by the Simple Network Management Protocol (SNMP) to contain attributes of their managed
systems. The Switch contains its own internal MIB.
multicast
Single packets copied to a specific subset of network addresses. These addresses are specified in
the destination-address field of the packet.
protocol
A set of rules for communication between devices on a network. The rules dictate format, timing,
sequencing and error control.
resilient link
A pair of ports that can be configured so that one will take over data transmission should the
other fail. See also
main port
and
standby port
.
RJ-45
Standard 8-wire connectors for IEEE 802.3 10BASE-T networks.
RMON
Remote Monitoring. Subset of SNMP MIB II which allows monitoring and management
capabilities by addressing up to ten different groups of information.
RPS
Redundant Power System. A device that provides a backup source of power when connected to the
Switch.
server farm
A cluster of servers in a centralized location serving a large user population.
SLIP
Serial Line Internet Protocol. A protocol which allows IP to run over a serial line connection.
SNMP
Simple Network Management Protocol. A protocol originally designed to be used in managing
TCP/IP internets. SNMP is presently implemented on a wide range of computers and networking equipment
and may be used to manage many aspects of network and end station operation.
Spanning Tree Protocol
(STP)
A bridge-based system for providing fault tolerance on networks. STP
works by allowing you to implement parallel paths for network traffic, and ensure that redundant paths are
disabled when the main paths are operational and enabled if the main paths fail.
stack
A group of network devices that are integrated to form a single logical device.
standby port
The port in a resilient link that will take over data transmission if the main port in the link
fails.
