SNMP
Simple Network Management Protocol: Originally designed for the Department of Defense network to support TCP/IP network management. It has been widely implemented to support the management of a broad range of network products and functions. SNMP is the IETF standard management protocol for TCP/IP networks.
Start of Header
A transmission control character used as the first character in the heading of an information message. (from Newton's Telecom Dictionary)
SONET
Synchronous Optical Network: An ANSI standard for transmitting information over optical fiber. This standard is used or accepted in the United States and Canada and is a variation of the SDH International standard.
Source Route
As used in this document, a hierarchically complete source route.
Source Traffic
A set of traffic parameters belonging to the ATM Traffic Descriptor used during the connection
Spanning Tree Algorithm
An algorithm, the original version of whcih was invented by Digital Equipment Corporation, used to prevent logic loops in a bridged network by creating a spanning tree. The algorithm is now documented in the IEEE 802.1d specifications, although the Digital algorithm and the IEEE 802.1d algorithm are not the same, nor are they compatible. When multiple paths exist, says PC Magazine’s Frank Derfler, STA lets a bridge use only the most efficient one. If that path fails, STA automatically reconfigures the network to make another path become active, sustaining network operations. This algorithm is used mostly by local bridges; it is
not economical for use over leased telephone circuits connecting remote bridges.1
SPE
SONET Synchronous Payload Envelope. The SONET frame format is divided into two main areas: Synchronous Payload Envelope (SPE) and Transport Overhead (TOH). The SPE contains the information being transported by the frame.
