Subject: complex capabilities
Hi, I had an action item to provide a proposal for what Heather calls "complex capabilities". Additionally, I describe how they are related to the FCAPS categories. Attached is a first attempt. Cheers, H. -- FCAPS is an acronym for a categorical model of the working objectives of network management defined by ISO. The characters in FCAPS represent five management categories: Fault, Configuration, Accounting, Performance, and Security. WSDM supports FCAPS by providing capabilities that match either one-to-one or in combination to the categories provided by FCAPS. These capabilities provide a more descriptive set of information that a managed resource can expose and a manager can provide. These WSDM capabilities are: Monitoring - Monitor the state, health, and usage information. The type of information that is captured in this category can be shared with end users. Aspects of FCAPS Fault and Accounting Management are supported through this capability. Control - Access to operations that allow changes to the state of managed resources. For example, start, stop, restart. This capability supports aspects of the FCAPS Fault and Accounting Management. Discovery - Attributes and Operations that provide how a managed resource is related to other managed resources and what events are provided to support the various life cycle aspects of a managed resource. Distribution aspects of the FCAPS Account Management can be supported through this capability. Performance - Overall performance of the network or application. Access to metrics proprieties, and the operations and notifications that effect them. This maps directly to the FCAPS performance management category. Configuration - Captures information related to provisioning of resources based on an overall performance of the network or application. This maps directly to the FCAPS configuration management category. Security - Captures primarily information about security of management information (e.g. use this kind of encryption when interacting with me). It should also additionally include information about management of security (e.g. what should be done if my private key is compromised). This capability does not cover all that is included in the FCAPS security category as the scope of WSDM is limited only to the management protocol. However, a management solution can use this capability in addition to channel based security requirements (e.g. HTTPS, etc.) to address what is offered through the FCAPS security category.
