E
EPS
EPS is an abbreviation for Ethernet Protection Switching defined in ITU/T G.8031.
ERPS
Ethernet Ring Protection Switching, or ERPS, is an effort at
sub-50ms protection and recovery switching for
there are no loops formed at the Ethernet layer.
Ethernet Type
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.
F
FTP
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.
Fast Leave
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.
H
HTTP
HTTP is an acronym for Hypertext Transfer Protocol. It is a protocol that used to transfer or convey information on the
World Wide Web (WWW).
HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take
in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP
command to the Web server directing it to fetch and transmit the requested Web page. The other main standard that
controls how the World Wide Web works is HTML, which covers how Web pages are formatted and displayed.
Any Web server machine contains, in addition to the Web page files it can serve, an HTTP daemon, a program that is
designed to wait for HTTP requests and handle them when they arrive. The Web browser is an HTTP client, sending
requests to server machines. An HTTP client initiates a request by establishing a Transmission Control Protocol (TCP)
ITU-T
under G.8032 Recommendation to provide
