Cpsw Module Functions; Control Plane - IBM Nways 8265 Product Description

CPSW Module Functions

Control Plane

The imbedded Control Point provides a complete set of functions to control an ATM
campus network and to interconnect local ATM networks over ATM wide area
networks.
The CPSW module acts as an SNMP agent that implements the ATM MIB. The
SNMP agent allows you to:
•
Configure ATM modules
•
Monitor ATM subnetworks.
Each IBM 8265 Control Point provides functions on three planes; the Control plane,
User plane, and Management plane.
•
Both Switched and Permanent Virtual Circuits (SVCs and PVCs)
•
User-to-Network Interface (UNI)
– Support of ATM signaling (SVC point-to-point and point-to-multipoint)
according to ATM Forum V3.0, V3.1, and V4.0 specifications.
– Support of permanent connections (PVC point-to-point and
point-to-multipoint). The setting of PVCs is supported in accordance with
PNNI Phase 1 Specification (soft-PVCs), ATM Forum.
– Support of internetworking between UNI V3.0, V3.1, and V4.0 end-systems.
– Support of ILMI V4.0.
•
UNI without ILMI Registration
– Some ATM devices from other vendors do not support the Interim Local
Management Interface (ILMI) registration process, which prevents them from
receiving incoming calls. With this extension, you can now connect these
devices to the ATM network through the 8265.
•
Network-to-Network Interface (NNI)
– Support of Interim Inter-Switch Signalling Protocol (IISP) according to ATM
Forum specifications.
– Support of link backup and load balancing between independent peer groups.
– Automatic call rerouting at peer group boundary through crankback.
•
Private Network-to-Network Interface (PNNI-1)
– Support of Private NNI (P-NNI Phase 1) according to ATM Forum
specifications).
– Support of Path Selection. Depending on network constraints, connections
types and network operator wishes, either precomputed or on-demand paths,
at either widest or shortest paths can be selected.
This is an optional feature available with Feature Codes 6506 and 6526.
•
Public UNI
– Support of connectivity to Public Networks via VP tunneling (without
supporting its signalling).
