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 On 8/13/13 10:49 AM, Chin Guok wrote:

Hi all,

We had a summer intern (Ahmed El-Hassany) working at ESnet on some topology stuff in the last couple months, and he put together a prototype topology service that might be useful for the NSI-WG.

Just some background, Ahmed was the primary architect of the GENI Topology service which uses the RSpec format, so he has a bunch of experience behind him. Unfortunately he has now taken up a research position at UC Berkeley, so the prototype topology service will remain in its current state till we find resources to further its development.

Having said that, a testing instance of the service is running at http://lstest.es.net:8080/urns. The documentation of using it is located at https://github.com/ahassany/topology-service/wiki/Using-NML-NSI-Topology-Ser....

All the tutorial topologies that Jeroen put up on GitHub (see forwarded email) has been loaded into the service.

You can list all NSAs by: curl http://lstest.es.net:8080/urns/

Or get a specific one by: curl http://lstest.es.net:8080/urns/urn:ogf:aruba.example:2013:nsa <http://lstest.es.net:8080/urns/urn:ogf:network:es.net:2013:nsa>

For tomorrow's meeting, Ahmed will do show-and-tell, so please log into www.readytalk.com and use the 7-digit access code 8937606 to access the "show" portion of the meeting.

Hi all,

I have created new topologies for the tutorials. These follow the same schema as the updated Automated GOLE topologies. The new tutorial topologies should follow the same topology as the old ones.

The domain names for all of them are "aruba.example" (using the IETF reserved namespace for examples).

They can be found at the tutorial repository:https://github.com/jeroenh/NSI-Tutorial-Topologies/tree/master/topos
