Dear Co-authors,

Please find comments on the nvo3 security requirements draft below.

>>REQ2: (Page 8)
This should recommend some authorization mechanisms such as md5 checksum.

>>REQ3: (Page 8)
>>b: The signaling packets SHOULD be encrypted.
We believe encryption should be an optional feature, since encryption impacts 
performance. This is okay as long as Authentication (REQ1) and Authorization 
(REQ2) are met.

>>5.1.1 Data Plane
Need additional requirements for tenant performance isolation so that one 
errant tenant does not affect the other; for example, if one tenant is facing 
an abnormal amount of traffic due to a behavioral security threat such as DDoS 
attack, it should not affect the performance of other tenants in a virtualized 
environment. We would be glad to provide additional text for this.

Thanks,
Ramki & Anoop
