Re: [Nfvrg] Research Group Preparation (a.k.a. "Last Call") for draft-irtf-nfvrg-gaps-network-virtualization

[Rafa Marin Lopez <[e-mail]>]

Dear authors:

I have reviewed the I-D and, in my opinion, it is well written and very comprehensible. Good work.

I have several minor comments:

1) OpenFlow is explicitly mentioned, however there is no reference to NETCONF or RESTCONF, which in my opinion are also important in this context.

2) Regarding security and privacy section. You mention somehow the possibility of a key material distribution ("For
   example, who will be in charge of provisioning and maintaining security credentials such as public and private keys?”). My comment is that we are contributing in I2NSF (https://datatracker.ietf.org/doc/draft-abad-i2nsf-sdn-ipsec-flow-protection/) in a way to manage IPsec SAs from a centralized security controller. In I2NSF, the Network Security Function (NSF) can be also a virtual NSF. My question is whether this is what you had in mind (management of security associations besides distributing credentials ).

3) Also under a security point of view, the AAA servers can be also considered as VNFs that needs to be managed, correct?. Just as a note, this may be related with this other (old) work about the management of AAA infrastructures (https://tools.ietf.org/html/draft-marin-sdnrg-sdn-aaa-mng-00)  

My 0.02 cents

Best Regards.
