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.
