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

tack 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

ervice 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 base 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

panning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for any bridged LAN. The

original STP protocol is now obsolete by RSTP.

SyncE

SyncE Is an abbreviation for Synchronous Ethernet. This functionality is used to make a network 'clock frequency'

synchronized. Not to be confused with real time clock synchronized (IEEE 1588).
