Glossary of Terms Filtering: Process whereby an Ethernet switch or bridge reads the contents of a packet and then finds that the packet does not need to be forwarded, drops it. a filtering rate is the rate at which a device can receive packets and drop them without any loss of incoming packets or delay in processing. Firmware: Alterable programs in semipermanent storage, e.g., some type of read-only or flash reprogrammable memory. Forwarding: Process whereby an Ethernet switch or bridge reads the contents of a packet and then passes that packet on to the appropriate attached segment. A forwarding rate is the time that it takes the device to execute all of the steps. Flash ROM: See ROM. Framing: Dividing data for transmission into groups of bits, and adding a header and a check sequence to form a frame. FTP: File Transfer Protocol, a TCP/IP protocol for file transfer. Full-Duplex: Independent, simultaneous two-way transmission in both directions, as opposed to half-duplex transmission. Gateway: A device for interconnecting two or more dissimilar networks. It can translate all protocol levels from the Physical layer up through the Applications layer of the OSI model, and can therefore interconnect entities that differ in all details. Hardware Address: See Network Address. Header: The initial part of a data packet or frame containing identifying information such as the source of the data, its destination, and length. 11-6 DSTni-XPress DR User Guide

packet does not need to be forwarded, drops it. a filtering rate is the rate at which a device can receive
packets and drop them without any loss of incoming packets or delay in processing.
Firmware:

Gateway:
Alterable programs in semipermanent storage, e.g., some type of read-only or flash reprogrammable
memory.
Forwarding:
Process whereby an Ethernet switch or bridge reads the contents of a packet and then passes that
packet on to the appropriate attached segment. A forwarding rate is the time that it takes the device to
execute all of the steps.
Flash ROM:
See ROM.
Dividing data for transmission into groups of bits, and adding a header and a check sequence to form a
frame.
FTP:
File Transfer Protocol, a TCP/IP protocol for file transfer.
Full-Duplex:
Independent, simultaneous two-way transmission in both directions, as opposed to half-duplex
transmission.
A device for interconnecting two or more dissimilar networks. It can translate all protocol levels from
the Physical layer up through the Applications layer of the OSI model, and can therefore interconnect
entities that differ in all details.
Hardware Address:
See Network Address.
Header:
The initial part of a data packet or frame containing identifying information such as the source of the
data, its destination, and length.
