RSTP
In 1998, the IEEE with document 802.1w introduced an evolution of STP: the
Rapid Spanning Tree Protocol, which
provides for faster spanning tree convergence after a topology change. Standard IEEE 802.1D-2004 now incorporates
RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.

SAMBA
Samba is a program running under UNIX-like operating systems that provides seamless integration between UNIX and
Microsoft Windows machines. Samba acts as file and print servers for Microsoft Windows, IBM OS/2, and other SMB
client machines. Samba uses the Server Message Block (SMB) protocol and Common Internet File System (CIFS),
which is the underlying protocol used in Microsoft Windows networking.
Samba can be installed on a variety of operating system platforms, including Linux, most common Unix platforms,
OpenVMS, and IBM OS/2.
Samba can also register itself with the master browser on the network so that it would appear in the listing of hosts in
Microsoft Windows "Neighborhood Network".
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.
