Title: Message

Zulah,

 

I believe that in your definition a few important points are missing. #1, #4, #3 second part, #5 second part, #6 second part of what I sent. Also it becomes very implementation focused. Sounds like if one would do 1-5 and 1-2 things will work, but that is not so unless some higher-level concerns (e.g. #5) are taken into account.

Subject: RE: [wsdm] [Uarch] processing model

 

I'd like to offer up the following two basic processing: discovery  (the process of gaining the understanding to interact) and interaction - for discussion.

 

I'm going to use MP = manageability provider and MS = manageability service and MC = manageability consumer.

 

Discovery:

1. The MC must determine the manageable resource to be managed

2. MP has a description of the information model for the manageability capabilities - access to which is provided via the MS. For each manageable resource that the MP is providing an MS for.

3. MC obtains the description of the appropriate MS and the associated information model

4. MC determines that it can interact - makes this possible

5. MC has endpoint reference for the appropriate endpoint with the capabilities that the MC wishes to use

 

Interaction:

1. MC understands and meets the endpoint requirements for interaction

2. MC monitors and controls resource by exchanging messages with the MS

 

After tomorrow's meeting, I can take an action to provide diagrams for this.

 

Zulah

Subject: [wsdm] [Uarch] processing model

I promised to start the Processing Model and Interaction Patterns section in Uarch, and so here is the first part -- the Processing Model. The diagram is attached and the words are as follows.

"
The compliant implementations of the roles defined in the logical model act according to the following basic processing rules:

#1: Manageability consumer and manageability provider have to understand information model in which semantics of a manageability capability is described. For example, it could be a UML model that expresses a group of properties, operations, events and metadata. Meaning of what model defines has to be equally understood by both parties.

#2: Manageability consumer exerts control over and obtains information about the manageable resource by exchanging messages with one or more manageability endpoints that provide access to the manageable resource.

#3: Manageability consumer has to be able to obtain the description of the manageability service, its endpoints and necessary manageability interfaces. Manageability provider has to be able to obtain description of the manageability interfaces for the capabilities it wants to support.

#4: Manageability consumer and manageability provider both have to equally understand how to establish which manageability interface corresponds to which manageability capability and vice versa.

#5: Manageability consumer establishes which capabilities are supported by the manageable resource either from the description of the manageability service or by exchanging messages with the manageability endpoint.

#6: Manageability consumer discovers necessary manageable resources by discovering manageable endpoints, reading their descriptions and exchanging messages as required. Manageability provider advertizes/registers available manageability endpoints.
