(Continuation of Questions 13/15 and 14/15)

Background and justification

As the level of functionality and intelligence in transport networks increases, the management requirements and supporting information models become more important. Recommendations are required for all types of transport equipment, e.g., optical, wireless, terrestrial, undersea, satellite, etc., defined in ITU-T Recommendations. Management requirements and information models for the interworking of standards-based transport systems/equipment and other equipment should be addressed.

ITU-T has established the TMN concept as a generalized framework for the definition of management requirements and supporting information models. Recommendations are needed for all types of standards-based transport equipment for which the management functions are required to be integrated into the TMN. Management requirements and information models should be based on the current ITU-T specified principles, functions, and techniques, for example as contained in Recommendations M.3010, M.3013, M.3020, and M.3400.

Responsibilities under this Question includes the following draft or published Recommendations:

G.774 Series: G.774, G.774.1 to G.774.10, SDH Information Models

G.784: Synchronous Digital Hierarchy (SDH) Management

G.874: Management Aspect Of the Optical Transport Network Element

G.875: Optical Transport Network (OTN) Management Information Model For the Network Element View

I.752: ATM Network Element Management

Question

• What management requirements and information models must be specified to enable efficient and effective management of transport equipment in interoffice and long distance networks, including evolution to the optical transport network?
• What management requirements and information models must be specified to enable efficient and effective management of transport equipment in interoffice and long distance networks, including evolution to an IP-enabled network?
• What management requirements and information models must be specified to support the interworking among equipment and systems of different transport technologies, e.g., various interworking combinations among IP, ATM, SDH/SONET, and OTN?
• What factors are necessary to match the management methodologies to the characteristics of the network equipment? Based on the Q-interface characterization in M.3010 and M.3013, what management protocols are appropriate for different classes of equipment? For example the use of suitable management protocols with equipment that has limited management capabilities.
• Should fast connection control using signalling protocols be considered for optical channels?
