WIMS> DiscoverAgents and Fix for RegisterForManagement

Hi,                                             Tuesday (10 August 2004)

Here are two problems that Harry Lewis identified in a phone call
last Friday:

(1) RegisterForManagement doesn't scale
    - one for EVERY end legacy or WIMS agent
    - not a reasonable model over the public Internet

(2) WIMS Manager can't request WIMS Proxy to do discovery
    - makes WIMS Proxy installation much more difficult

Below are proposed solutions.

Cheers,
- Ira

------------------------------------------------------------------------

(1) Add one new parameter to RegisterForManagement operation
RegisterForManagement (sourceURI : URI, targetURI : URI,
    agentURIs : URI,
    operations : WIMSOperationsSupported,
    actions : WIMSActionsSupported,
    objects : WIMSObjectsSupported)
        statusString : StatusString,
        operations : WIMSOperationsSupported,
        actions : WIMSActionsSupported,
        objects : WIMSObjectsSupported,
        schedule : Schedule

Parameters:

    agentURIs : xsd:anyURI
    - URIs of the WIMS Agents or Legacy Agents currently managed by this
    WIMS Proxy.  These values MAY use the 'pwg-wims:' URL scheme and
    MUST conform to [RFC2396].
    Note:  This parameter allows a WIMS Proxy to bundle multiple
    registrations into a single operation sent to a WIMS Manager (for
    scalability of the WIMS protocol to large networks).

(2) Define new DiscoverAgents WIMS action

DiscoverAgents (targetURI : URI,
    parameters : any)

Description:
    Discover legacy and WIMS agents visible to this WIMS Proxy, which
    MUST include a list of the discovered Agent URIs in a subsequent
    RegisterForManagement to the WIMS Manager identified in the Schedule
    or ExecuteAction.

Parameters:
    targetURI : xsd:anyURI
    - URI of the WIMS Proxy to perform the discovery.  This value MUST
    use the 'pwg-wims:' URL scheme and MUST conform to [RFC2396].
    parameters : pwg-sm:ActionElementAny
    - Vendor extension parameters from any namespace.
