Technical Specifications

This appendix lists the relevant technical and compliance specifications for the SES PNNI controller, PNNI and ATM switched virtual circuits in the following sections:

Note Physical specifications for the Service Expansion Shelf are listed in the Cisco Service Expansion Shelf Hardware Installation Guide.

The SES PNNI controller PNNI routing software was designed to be compliant with 1 below. The software supports robust topology convergence, dynamic and QoS based routing in hierarchical ATM networks with scalability from small to very large networks.

The software must also be upgradable to support all enhancements defined in the PNNI V2.0, currently being developed by the ATM Forum.

LANE, Classical IP over ATM, and MPOA will not be implemented as part of the SVC services in the SES PNNI controller, but will be supported when they are running on equipment directly or indirectly connected to it.

VTOA is implemented on MGX8850 Release 1.0. BPX/SES will support VTOA when MGX8850 Release 1.0 become a feeder node for BPX/SES.

SPVC service is supported and implemented in BPX/SES PNNI Controller in this release.

Interoperability Support

The SES PNNI controller is interoperable with all standards-compliant networking equipment.

The SES PNNI controller is also backward compatible with ESP v2.X.
