This MIB module is used for configuring ATM Capable Switch
to be aware of VSI Controller information.
VSI - Virtual Switch Interface, a hardware-independent switch
control protocol. This allows a Switch(node) to be
controlled by a multiple controllers such as PNNI,LSC.
These control planes can be internal or external to the
switch.The VSI interface defines the messages and associated
functions which allow communication between the controller
and the switch.This interface is expected to support all
types of connections (voice,data,frame relay,ATM) for PVCs,
SPVCs and SVCs.
VSI Master - software component which requests connections and receives
switch generic information. This controls one or more VSI
Slaves. This may run on the switch or a dedicated controller
platform. This is the master module.It performs the interface
to the higher layer networking software and handles all VSI
VSI Slave - software component which converts generic connection
requests into hardware specific requests and hardware
specific information into generic information.
This runs on the switch.a A centralized slave has a single
point of control for making connections and controlling
interfaces, while a distributed slave allows for multiple
slaves to coexist on the same switch.
Controller - Software ( and possibly hardware) which manages topology
and network resources and performs VSI Master fucntion.
This performs source routing for ent-to-end SVCs, including
general call acceptance GCAC,setup calls with other
PNNI and MPLS are examples for the Controller.
Controller Shelf - A controller shelf is a switch containing atleast
one VSI Controller which is controlling a different
switch.It will also, typically, contain 'local' controllers
