This draft Recommendation defines a set of services required to support service-oriented Web-service based interfaces, and along with ITU-T X.ws-xml composes a framework for Web-service based network management interface. It specifies protocol requirements, how some well-known Web-services should be used in network management interfaces, and defines some network management specific support services. The WSDL interface definitions for the network management specific support services are also provided. This draft Recommendation defines a set of guidelines for managed object modelling and management interface for Web-service based network management. It specifies how service-oriented Web service interfaces should be defined. It covers the suitable application scenario of Web-services in network management interfaces, generic accessing methods of XML based managed objects, information modelling in Web-service WSDL and XML Schema. Some WSDL definitions and XML Schema are provided defining some basic data types, generic managed object (MO) and generic MO accessing methods. This draft Recommendation and draft ITU-T Recommendation Q.ws-xml together compose a framework for Web-service based network management interfaces with a wide range of applications.
