The MIB module to manage resource partition objects. A resource partition is configured on a virtual interface (ifType value atmVirtual(149)) or atm interface (ifType value atm(37)). An administrator can partition connection related resources like VPI, VCI ranges, bandwidth and total amount of available connection entries in the switch through these MIB tables. Terminolgies used: VSI - Virtual Switch Interface, a hardware-independent switch control protocol. This allows a Switch to be controlled by a multiple controllers such as PNNI, MPLS. 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 related functions. Controller - Software ( and possibly hardware) which manages topology and network resources and performs VSI Master function. This performs source routing for end-to-end SVCs, including general call acceptance GCAC,setup calls with other controllers. PNNI and MPLS are examples of controllers. ILMI - Integrated Local Management Interface (ILMI). An ATM Forum defined, SNMP-based management protocol for an ATM UNI. It provides interface status and configuration information, and also supports dynamic ATM address registration. CAC - Call Admission Control (CAC). When a new call coming to the gateway, a process checks the availability of the resources involved in the connection establishment before the gateway sets up the call. ATM - Asynchronous Transfer Mode (ATM). PNNI - Private Network to Network Interface (PNNI). MPLS - MultiProtocol Label Switching (MPLS). GCAC - Generic Connection Admittance Control (GCAC). PVC - Permanent Virtual Circuits (PVC). SVC - Switched Virtual Circuits (SVC). SPVC - Soft Permanent Virtual Circuits (SPVC). VPI - Virtual Path Identifier (VPI). VCI - Virtual Circuit Identifier (VCI).
