DNS is an acronym for Domain Name System. It stores and associates many types of
information with domain names. Most importantly, DNS translates human-friendly
domain names and computer hostnames into computer-friendly IP addresses. For
example, the domain name www.example.com might translate to 192.168.0.1.
DoS
is an acronym for Denial of Service. In a denial-of-service (DoS) attack, an
attacker attempts to prevent legitimate users from accessing information or
services. By targeting at network sites or network connection, an attacker may be
able to prevent network users from accessing email, web sites, online accounts
(banking, etc.), or other services that rely on the affected computer.
Dotted Decimal Notation refers to a method of writing IP addresses using decimal
numbers and dots as separators between octets.
An IPv4 dotted decimal address has the form x.y.z.w, where x, y, z, and w are decimal
numbers between 0 and 255.
DSCP is an acronym for Differentiated Services Code Point. It is a field in the header
of IP packets for packet classification purposes.
EEE is an abbreviation for Energy Efficient Ethernet defined in IEEE 802.3az.
EPS is an abbreviation for Ethernet Protection Switching defined in ITU/T G.8031.
Ethernet Type, or EtherType, is a field in the Ethernet MAC header defined by the
Ethernet networking standard. It is used to indicate which protocol is being
transported in an Ethernet frame.
FTP is an acronym for File Transfer Protocol. It is a transfer protocol that uses the
Transmission Control Protocol (TCP) and provides file writing and reading. It also
provides directory service and security features.
Multicast snooping Fast Leave processing allows the switch to remove an interface
from the forwarding-table entry without first sending out group specific queries to
the interface. The VLAN interface is pruned from the multicast tree for the multicast
group specified in the original leave message. Fast-leave processing ensures optimal
bandwidth management for all hosts on a switched network, even when multiple
multicast groups are in use simultaneously. This processing applies to IGMP and
MLD.
