scope:

The network management architecture defined in [ITU-T M.3010] introduces the use of multiple management protocols. So far, the GDMO/CMIP and CORBA GIOP/IIOP are possible choices at the application layer. Based on the management interface specification methodology defined in [ITU-T M.3020], more technology-based paradigms can be introduced into network management interfaces and web service/XML is now an additional paradigm for network management.

This Recommendation, together with [ITU-T Q.818] sets out to define a framework for defining how interfaces supported by management systems and network elements should be modelled using web service/XML schema. It is within the scope of this Recommendation to provide the following guidelines or instructions:

- service-oriented WSDL-based interface design approach;

- suitable and unsuitable application scenarios for web services in network management interfaces;

- generic accessing methods for managed objects;

- inheritance of managed objects and interfaces;

- information modelling guidelines for web services-based interfaces;

- style conventions for web service WSDL and XML schema specifications.
