About this document
This document describes the Integrated Network Management (INM)
Broadband Release 4.1 application which provides centralized management
across multiple controller subnetworks. INM Broadband Release 4.1 provides
a common network management framework which includes a common
hardwareandsoftwareplatform for allapplications,a GraphicalUser Interface
(GUI) for day-to-day operations, and open Applications Programming
Interfaces (APIs) to facilitate customization and adaptation for a wide variety
of broadband network elements.
INM Broadband Release 4.1 combines the functionality of the previous Nortel
network management graphical user interfaces provided by the S/DMS
Network Manager or INM Broadband products with the Information
Networking Architecture (INA) Transport product, which provided open
interfaces based on the HP DPE technology.
In INM Broadband Release 4.1, all existing HP DPE APIs are replaced with
CORBA APIs, thereby migrating to a new and open standards based
architecture. Beginning with INM Broadband Release 4.1, CORBA becomes
the technology of choice for distributed network management applications.
INM Broadband Release 4.1 is the first release of Integrated Network
Management targeted at both the SONET Broadband and ATM marketplaces.
It extends the graphical network management functionality offered in previous
releases of Network Manager/INM, and combines it with CORBA APIs to
form one single product offering.
The INM Broadband Release 4.1 product portfolio has the following
characteristics:
• It is a suite of software applications deployed on Hewlett-Packard 700
Series workstations.
• It contains open, standards-based Common Object Request Broker
Architecture (CORBA) interfaces to manage Nortel and non-Nortel
network elements.
• It provides graphical user interfaces for centralized network management.

Integrated Network Management Broadband Release 4.1 PG OC 98-13 Issue 1.2
INM not only provides for surveillance but also provides for provisioning,
performance monitoring, shelf level graphics, protection control, centralized
software management, and inventory collection. INM provides a single point
of operational access for multiple S/DMS TransportNode OC-3/12/48/192
subnetworks, S/DMS AccessNode, SONET Radio, DV-45, Tellabs Titan 5500
Digital Cross-Connect systems (DCS), OC-3 Express, JungleMUX, INM
NETWORKS NEs as well as Nortel ATM Passport Network Elements and
potentially other network elements through a graphical consolidated view
which may encompass thousands of widely separated individual Network
Elements (NEs).
Common Object Request Broker Architecture
An Overview
Common Object Request Broker Architecture (CORBA) is a multi-vendor
standard for object-oriented distributed computing. CORBA technology is
based on specifications defined by the Object Management Group (OMG)
which is a consortium of computing involved companies. The OMG is an
international organization of over 600 members, and includes all of the major
vendors of systems and software from around the world, as well as
independent software vendors, large and small consulting companies, and an
increasing number of end user companies.
The OMG only produces specifications and not software. The specifications
are freely available for any company to implement. An implementation of
CORBA is referred to as an ORB (Object Request Broker). There are many
ORBs in the marketplace today, Nortel has chosen Orbix, from Iona
Technologies as its distributed middleware CORBA technology to provide the
capabilities to develop distributed applications around its INM Broadband
Release 4.1 product.
Rapidly changing technologies, increased complexity and need for
responsiveness to customer needs have led telecommunication service
providers such as Nortel to explore new and novel methods for deploying new
telecommunications systems and networks. As a result, the telephony world
has devoted a significant amount of time developing architectures such as
Telecommunications Management Network (TMN).
Concurrent with efforts made in the telecommunication world, the computing
world has been developing and refining concepts, architectures and platforms
such as OMG CORBA that enable software modules to cooperate and
communicate transparently across different implementations of operating
system, hardware and networks.
