[Nsi-wg] Request for developer for NSI visualisation software

[Tomohiro Kudoh]

Hi Jerone, Henrik and all,

The query behavior is specified as:

 *                 Supports querying reservations based on connectionId or
 *                 globalReservationId. Filter items specified are OR'ed to build
 *                 the match criteria. If no criteria is specified then all
 *                 reservations associated with the requesting NSA are returned.

Therefore, for an external agent such as viewer to get information by
query, the external agent should know connectionIDs or
globalReservationIds of reservations somehow.

Tomohiro

I dislike the idea of starting to build a parallel infrastructure for a task which is supposed to be solvable with the NSI protocol. Sure, the polling nature of query and the high entrance bar for SOAP+WSDL is probably not ideal, but I think we should at least try to build something using it, before we start on the parallel infrastructure. If it doesn't work or becomes to convulated or complex, perhaps we should reconsider parts of the protocol. If we cannot use NSI, who can?
