(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?
