Management Architectures and Their Submodels

• Management Platform is
• The framework for management relevant standards
• Architectures as the prerequisite for Open
  Platforms (3 fundamental approaches)
• Isolated approach
• Isolated tools for each management problems
  (tools work independently of one another)
• Coordinated approach
• Coordinated tools complementing each other to a
  function)
• Integrated approach
• Integration of tools in heterogeneous environment
  providing non-vendor-dependent information.
• Open management platforms form the basis for an
  integrated approach

5
Management Architectures and Their Submodels

• Management Platform on a multivendor basis must
  have
• Description of managed objects (IM)
• Treatment and support of organizational aspects,
  roles, and cooperation forms( OM)
• Description of communication processes for
  management purposes (CM)
• Structuring of management functionality (FM)
• A framework for management relevant standards
  with respect the above four aspects is called
  management architecture.

6
Information Model

• IM controls
• The methods used for modeling and describing
  management objects
• Managed objects represent the characteristics
  of the resources on which management operates
• MIB (management information base) describe the
  set of managed objects managed by a manager or an
  agent system
• IM of a management architecture defines the
  entity, data type, object orientation
• For Management interoperability to be success,
  heterogeneous networked systems must interact
  meaningfully with management purposes
• Standard Management models established
  prerequisites for management interoperability

7
Organizational Model

• OM controls
• There are different structures that forms the
  organizational architectures Management
  architectures should encourage the variety of
  forms that characterized the organizations by
  providing options for adaptation
• The architectures enables forms of cooperation,
  roles, and ways groups are organized
• Topological and Functions of Management System
• Multipoint control, Multicenter control,
  Hierarchical management, Central management, and
  Network of managers Figure 4.4 -page 111
• Central management One MS is responsible for
  all tasks (having multipoint control)

8
Organizational Model

• OM controls
• The organization model of a management
  architecture defines the actors, their roles, and
  the fundamental principles of their cooperation
• Two forms of management cooperation
• The manage-agent model (asymmetrical-hierarchical)
  cooperation form assumes a customer-provider
  relationship for its cooperation (like
  client-server relation)
• The completely (symmetrical) cooperation form
  that emanates from the communication and
  cooperation of equal objects
• OM domains concept define management views of
  groups of resources
• OM policy concept define domain-specific
  management rules
• Communication Model
• Management (monitoring and control of potentially
  physically dispersed resources)
• CM of management architecture is the exchange of
  information between the actors

9
Communication Model

• CM controls
• Communication takes place
• Through an exchange of the control information
  about a managed resource or object (controlling).
  Manager!
• Through a status request (monitoring). Manager!
• Through asynchronous event messages in the system
• CM deals with the following aspects
• Specify the communication partners
• Specify the communication mechanism
• Define the syntax and semantics (exchange
  formats)
• Embed management protocols

10
Functional Model

• FM controls
• FM of management architecture divides the
  complexity of management into management function
  areas (configuration, fault, accounting
  management)
• FM provides the basis for the management building
  block
• Stepwise refinement is the approach taken to the
  development of function and service modules
• Management by delegation allows for flexibility
  and scalability
• CM deals with the following aspects
