S
SHA
SHA is an acronym for Secure Hash Algorithm. It designed by the National Security
Agency (NSA) and published by the NIST as a U.S. Federal Information Processing
Standard. Hash algorithms compute a fixed-length digital representation (known as a
message digest) of an input data sequence (the message) of any length.
Shaper
A shaper can limit the bandwidth of transmitted frames. It is located after the ingress
queues.
SMTP
SMTP is an acronym for Simple Mail Transfer Protocol. It is a text-based protocol that
uses the Transmission Control Protocol (TCP) and provides a mail service modeled on
the FTP file transfer service. SMTP transfers mail messages between systems and
notifications regarding incoming mail.
SNAP
The SubNetwork Access Protocol (SNAP) is a mechanism for multiplexing, on networks
using IEEE 802.2 LLC, more protocols than can be distinguished by the 8-bit 802.2
Service Access Point (SAP) fields. SNAP supports identifying protocols by Ethernet type
field values; it also supports vendor-private protocol identifier.
SNMP
SNMP is an acronym for Simple Network Management Protocol. It is part of the
Transmission Control Protocol/Internet Protocol (TCP/IP) protocol for network
management. SNMP allow diverse network objects to participate in a network
management architecture. It enables network management systems to learn network
problems by receiving traps or change notices from network devices implementing SNMP.
SNTP
SNTP is an acronym for Simple Network Time Protocol, a network protocol for
synchronizing the clocks of computer systems. SNTP uses UDP (datagrams) as transport
layer.
SPROUT
Stack Protocol using ROUting Technology. An advanced protocol for almost instantaneous
discovery of topology changes within a stack as well as election of a master switch.
SPROUT also calculates parameters for setting up each switch to perform shortest path
forwarding within the stack.
SSID
Service Set Identifier is a name used to identify the particular 802.11 wireless LANs to
which a user wants to attach. A client device will receive broadcast messages from all
access points within range advertising their SSIDs, and can choose one to connect to
based on pre-configuration, or by displaying a list of SSIDs in range and asking the user
to select one (wikipedia).
SSH
SSH is an acronym for Secure SHell. It is a network protocol that allows data to be
exchanged using a secure channel between two networked devices. The encryption used
by SSH provides confidentiality and integrity of data over an insecure network. The goal
of SSH was to replace the earlier rlogin, TELNET and rsh protocols, which did not provide
strong authentication or guarantee confidentiality (Wikipedia).
