[Sdnp] updated SDN problem statement draft

[Ken Gray]

In section 3.1, will the architecture define:

A plug-in/modular architecture to accommodate multiple topology sources (BGP-TE, ALTO, etc)?
A plug-in/modular architecture to accommodate the multiple provisioning tools available (PCE, OF, your-brand-of-IP-tunnel, etc)?

I'm just looking for the value statement here, and one of the problems (to me) is the proliferation of options on these "interfaces" (as far as building the perfect application beast goes).  So, for topology, for example … would the Service Mediator define some sort of topology abstraction at ingest that normalizes the formats of the example topology providers above …or maps provisioning capabilities per object managed to hide the syntactical/semantic differences between cross-connecting a flow with OF vs some-other-config-semantic?

Other than a platform to tie together all the elements, what will the value add be …

Subject: Re: [Sdnp] updated SDN problem statement draft

The new draft is trying to outline:

1. What is it? An overlay architecture that presents the underlying network to the applications for monitoring and provisioning at abstraction level.

2. Architecture outline: after speaking to many and tried out quite a few solutions, here is the architecture that we believe is reasonable. (more details to follow)

3. Use cases: network slicing, virtual dc and l3 hypervisor. (more details to follow)

Please take a look, and provide comment.

(Sorry about many editing mistakes, as we are bouncing between projects)
