[Nsi-wg] Please begin testing

Hi All-

I did not mean to imply everyone had to implement an HTTPS interface - I 
just meant the issue needs to be resolved and the solution tested.

The Spec says "authenticated and secure" - but it does not require 
HTTPS.   So we are in grey area.    For the SC demo we will do the 
following:

1- The Aggregator NSAs *should* implement both HTTPS and HTTP transports 
for their RA.  This will allow them to segment requests to either type 
of PA.   The aggregator NSAs are G-LAMBDA-A, AutoBAHN, and OpenNSA.  
(OpenNSA plans to implement both modes for the RA for the SC demo...but 
will be close.  TK: What about GL-A?  RK: Is this possible for AB prior 
to SC?

2- For the SC demo, PAs can do either HTTP or HTTPS.  The RA client must 
be able to conform to the PA they intend to interact with.

If your client RA is HTTP only, and it wants to interact with a HTTPS 
only PA, it can forward its primitive request to an HTTP Aggregator PA 
which will "segment" the request and send it to the HTTPS PA.  This adds 
one layer to the service tree, but is otherwise is a fully compliant 
property of the protocol.

Does this help resolve the problem?

We still do not have HTTPS and can’t talk with DRAC at NetherLight, who is direct peer and GEANT related NRENS way to US and Japan. It's critical for us. I would appreciate if for SC demo we could use HTTP mode as well.
