Hi, all,

The updated text looks good to me.

Regards,

We (Lou and I) hacked on the wording a little bit, mainly from a clarification standpoint (not really trying to substantively change anything). The changes are in the etherpad: http://etherpad.tools.ietf.org:9000/p/teas-actn-def<http://www.google.com/url?q=http%3A%2F%2Fetherpad.tools.ietf.org%3A9000%2Fp%2Fteas-actn-def&sa=D&sntz=1&usg=AFQjCNFF5PidSDEuHcotj1m0c2gkQnTa8A>

Please feel free to go edit it. One open question we have (and is on the etherpad) is on the use of customer vs client (was a bit inconsistent). We don't have a strong opinion on which, and have changed the single instance of "client" to "customer".

Let us give folks a little bit more time to chime in on this thread.

Pavan and Lou

Hi Lou,

Here's the updated version and also in word if that helps.

Thanks.
Young

----------------------------------------------------------------------------------------------------

Abstraction and Control of TE Networks (ACTN) is aimed to support virtual network operations needed to orchestrate, control and manage large-scale multi-domain TE networks so as to facilitate network programmability, automation, efficient resource sharing, and end-to-end virtual service aware connectivity and network function virtualization services. These are summarized as follows.

-       Abstraction and coordination of underlying network resources to higher-layer applications and customers, independent of how these resources are managed or controlled, so that they can dynamically control their virtual networks by creating, modifying, monitoring, and deleting them.

-       Multi-domain and multi-tenant virtual network operation via hierarchical abstraction of TE domains that facilitates multi-administration, multi-vendor, and multi-technology networks as a single virtualized network. This is achieved presenting the network domain as an abstracted topology to the customers via open and programmable interfaces. This allows for the recursion of controllers in a customer-provider relationship.

-       Orchestration of end-to-end virtual network services and applications via slicing of network resources to meet specific service, application and customer requirements.

-       Adaptation of customer requests (made on virtual resources) to the physical network resources performing the necessary mapping, translation, isolation, security, and policy that allows conveying, managing and enforcing client policies with respect to the services by the network to said customers.

-       Provision of a computation scheme and virtual control capability via a data model to customers who request virtual network services. Note that these customers could, themselves, be service providers.

Young,

In the process thread, you said:

can you send the proposed wording? (presumably on top of Igor's changes)

Thanks,
Lou

Now it is certainly normal and good practice for  WG chairs to ensure support for the work via such things as polls, but this isn't procedurally required.  Also, chairs always evaluate the filename as part of our approval process, and while less common,  approve file names different than the form used by the individual draft.  Feel free to look around and you'll find a few examples.
