[Nsi-wg] Open dynamicKL NSA

Wed Sep 7 13:55:50 CDT 2011

All,

I generated a request through OpenDRAC and here is the format of the reservation message.  I have compared it to Henrik's message and there is definitely an issue with the "<ns6:reservation>" in my message and the "<ns0:reservation>" in his message since they are from two separate namespaces.  If you look in the file ogf_nsi_connection_interface_v1_0.wsdl you will see that ReservationRequestType is referencing the reservation message definition (ref="types:reservation") from the type namespace.  This means that <ns6:reservation> shown below is correct.  Henrik's implementation seems to be using the interface namespace.  Looks like there is a bug in his SOAP stack.  Now we can get around it but I will need to modify the WSDL definition to not reference elements, but use imported types instead.  This will require everyone to make changes to their implementations.  I assume this is too risky for Rio...

John.
