EEE
EEE is an abbreviation for Energy Efficient Ethernet defined in IEEE 802.3az.
EPS
EPS is an abbreviation for Ethernet Protection Switching defined in ITU/T G.8031.
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. 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) connection to a particular port on a remote host (port 80 by default). An
HTTP server listening on that port waits for the client to send a request message.
HTTPS
HTTPS is an acronym for Hypertext Transfer Protocol over Secure Socket Layer. It is
used to indicate a secure HTTP connection.
HTTPS provide authentication and encrypted communication and is widely used on the
World Wide Web for security-sensitive communication such as payment transactions and
corporate logons.
HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer
under its regular HTTP application layering. (HTTPS uses port 443 instead of HTTP port
80 in its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size for the RC4
stream encryption algorithm, which is considered an adequate degree of encryption for
commercial exchange.
