[Nsi-wg] Topology Service presentation/demo for NSI call for tomorrow (Wed 8/14)

[Chin Guok]

Hi all,

Just a quick recap of the topology presentation this morning.

- the topology service in its current form is a prototype suitable for demos
- for production deployment, there are some fundamental issues that need 
to be worked out, such as bootstrapping, security, and authenticity
- an interim step might be to limit posting of topology, and make it 
"read-only"
- more discussion on this is necessary to formalize a production 
deployable service.

In terms of the bootstrapping, security, and authenticity issues, we can 
look at how the GENI folks approached it.  The work Ahmed did with GENI 
can be found at http://incntre.iu.edu/research/Gemini, it was a GENI 
grant to IU with Martin Swany as the PI.

If folks have any further comments or suggestions, please feel free to 
send it this way.

Thanks!

- Chin
