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).
SSM
SSM In SyncE this is an abbreviation for Synchronization Status Message and is containing a QL
indication.
STP
Spanning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for any
bridged LAN. The original STP protocol is now obsoleted by RSTP.
