List of terms
soft permanent virtual path (SPVP, soft PVP)
Soft PVPs support the same functionality as a permanent virtual path but eliminate the need to manually provision each node along the connection. The endpoint is provisioned but the connection route is selected automatically.
software control system (SCS)
The software system that manages the software installed in a shelf. It controls the downloading of software, cleans up unused software on the Nortel Multiservice Switch node disk, and determines which software modules need to be loaded on each processor card.
software distribution site (SDS)
A workstation designated to manage, store, and provide access to Nortel Multiservice Switch software.
SONET
See synchronous optical network (SONET) standard (page 131).
SONET payload envelope (SPE)
The user data of a SONET signal.
source/destination
The name of the endpoints of an ABR loop when considered in a given single direction. ABR requires that a network is divided into ABR loops with a source and destination at either end of the loop. The direction from source to destination is the direction of traffic flow. For traffic in the reverse direction, the source and destination roles are reversed. See resource management (RM) cell (page 113).
source node
The node that originates the connection.
source route
In ATM PNNI networking, a route that has been determined by the source node to the destination node. As a result of this calculation, a source route includes a complete designated transit list (DTL), which is based on the distributed topology information that is available at the time the calculation is made.
source routing
A routing approach in which the source node determines the route to the requested destination before setting up the call.
SP
See security policy (SP) (page 118).
