Next Generation Network Management and Common Info
Alex Zhdankin, Harris Corporation
One of the important aspects in management of Next Generation Networks is to provide ability for Service Providers to implement seamless end-to-end management solutions spanning several management domains.
Different management domains are addressed using different modeling techniques. CIM is focusing on the IT resources management (Systems, Storage and IP Networks), MTNM and some other models are addressing SONET/SDH, Asynch/PDH, DWDM, ATM, Frame Relay and DSL management domains, SID provides a description of the telecom service provider's total technical and business systems. NGN Management defines a set of management Functions and Function blocks, which exist in NGN and should be implemented by end-to-end NGN Management Solution. Usually, these functions belong to different management domains and are realized by products from different vendors.
These products may use different information models that suit better to the particular areas of the products specialization. In order to provide NGN end-to-end management solution it is necessary to integrate these products. Different models need to be compared, matched and possibly modified in order for integration to happen. This is realized through the process of model harmonization.
There are two Generic Information Models which were both inputs to the NGN Roadmap - TMF Shared Information and Data Model (SID) and DMTF Common Information Model (CIM). Harmonization between CIM and SID needs to occur within operational domains where these models need to coexist in order to provide interoperability between different management solutions used for NGN. The CIM-SID Harmonization activity is a joint effort between the Distributed Management Task Force (DMTF) and the TeleManagement Forum (TMF). As a result of this activity new model harmonization methodology based on existence of shared semantic concepts is being developed.
From this presentation the attendees will learn about current model harmonization activities that are going on between different Standard Development Organizations in the context of NGN Management and DMTF and TMF in particular and will learn about new model harmonization methodology that is currently being developed jointly by DMTF and TMF.
SBLIM Data Gatherer - A CIM Metrics Model Implementation
Viktor Mihajlovski, IBM
The CIM Metrics Model provides a flexible and powerful way of presenting additional information about elements of CIM models without the need to extend the underlying model. The SBLIM Data Gatherer - a package of the SBLIM project - is an efficient implementation of the Metrics Model for Linux. It's key components are a distributed plugin-extensible data gathering infrastructure and a set of generic CMPI providers.
The presentation will cover the architecture of the Gatherer and show how Metric Definitions and Metric Values can be added via appropriate plugins.
Application of Model Driven Architecture
Jennifer Hickey, Harris Corporation
In today's convergent environment it is practically impossible to provide seamlessly integrated management throughout multiple management domains without proper modeling of managed resources. The models used by the management system must be consistent across the entire management environment, whether they describe IT or Telecommunication resources. The process of creation of such models is very complex and requires a lot of domain expertise coupled with detailed knowledge of Common Information Model (CIM). Also, the existence of a wide variety of management protocols and differences between MIBs of individual managed resources makes it even harder to provide proper instrumentation for the unified model representation. All of these factors make creation of an integrated Operation Support System a difficult task. Fortunately, Model Driven Architecture (MDA), developed by OMG, can help.
Use of MDA eases the transition from business-oriented, management-domain specific models. It helps to reduce modeling complexity and enables production of a well structured CIM model, consistent across multiple management domains.
A flexible MDA-based platform enables rapid deployment of managed resources, allowing developers to spend more time on domain-specific problem analysis and less time on the management solution implementation.
From the presentation, attendees will learn about application of Model Driven Architecture to the management of convergent IT and Telecommunication resources of today?s Enterprise. They will be introduced to the details of a streamlined modeling process for network and enterprise resources using UML 2.0, OCL, code generation algorithms, etc., which help in creation of consistent CIM-based models by the users focusing on the particular management domain. In addition, attendees will learn about the end-to-end MDA-based process of rapid design and development of management agents.
Grid Computing and Databases
Guru Bhat, Oracle Corporation
This presentation seeks to tie in the concept of Grid/Utility Computing and how Databases can harness the power of this infrastructure. The presentation will delve into the definition of Grid Computing, why it is necessary and explain the fundamental attributes of the grid. It will also explain in detail how Grid Computing and Databases fit together and also talk about the EGA and how the DMTF and the EGA work together in this arena.
Using Information Models for Grid
Ellen Stokes, IBM
Resources in a grid need to advertise their capabilities and activities in a grid need to consume those resources. This session will discuss how resources will be modeled in Open Grid Forum's OGSA (Open Grid Services Architecture) to advertise their capabilities and for acitvities to consume those resources. It leverages the wealth of existing systems management information (e.g. DMTF CIM) already modeled and instantiated in systems today using XML and XQuery. Examples and a demo are included.
