ITU-T SG 15 Question 14/15 |
|
Management and control of transport systems and equipment (Continuation of Question 14/15)
- Motivation
As the level of functionality and intelligence in transport networks increases,
the management and control requirements and supporting information models for
these networks become more important. Management/Control Recommendations are
required for all types of transport equipment, e.g., optical, wireless,
terrestrial, submarine, satellite, etc., defined in ITU-T Recommendations.
Management/Control requirements and information models for the interworking
of standards-based transport systems/equipment and other equipment are essential
to realize the full value of modern transport networks.
ITU-T has established the Telecommunications Management Network (TMN)
concept as a generalized framework for the definition of management
requirements and supporting information models. Recommendations are
needed to integrate into the TMN framework the management functions
of modern, standards-based transport equipment. 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.
ITU-T is creating standards on Automatically Switched Optical Networks
(ASON) and their control mechanisms. Specifically, the ASON control
mechanisms support both the activation of efficient connection
configurations in a transport layer network and fast optical
restoration. An architecture framework has been defined in
Recommendations G.807/Y.1302 (requirements) and G.8080/Y.1304
(architecture) for ASON. Recommendations for the protocol-neutral
requirements and protocol solutions are needed for ASON control,
discovery, and management.
The following major Recommendations, in force at the time of approval
of this Question, fall under its responsibility: G.774-series, G.784,
G.874-series, G.875, G.876, G.7710/Y.1701, G.7712/Y.1703, G.7713/Y.1704-series,
G.7714/Y.1705-series, G.7715/Y.1706-series, G.7718/Y.1709-series, and I.752.
- 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 (OTN),
IP networks and Next Generation Networks (NGN)?
- 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, OTN, MPLS,
and Ethernet?
- What factors should be considered to identify management
methodologies best suited to the characteristics of 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 what management protocols are best
suited to equipment that has limited management capabilities.
- What control requirements and protocol solutions must be
specified to enable efficient and effective signalling, routing,
automatic discovery, and management of ASON?
