Hi Fabio, Dear all

I have a couple of observations:
t

1.     The quality of the contribution appears to be excellent, however there 
is one thing: the text appears to be kind of loose regarding what the LISP 
Instance ID identifies. While it is not wrong to state that the LISP Instance 
ID identifies the tenant, such wording is misleading. The LISP Instance ID does 
not directly identify the tenant. I suggest to more correctly state, that the 
LISP instance ID identifies a virtual network (this occurs in multiple places 
throughout the document). Of course there will be somewhere some table mapping 
the virtual network to a virtual data center, and the virtual data center to a 
tenant, with whom the virtual datacenter and therefore the virtual network 
belongs.

2.     In that context, I would recommend to the authors of the NVO3 framework 
document to review the definition of tenant. Is a tenant really a “customer”, 
or rather a subscriber of a business service, that is authorized by a customer?

The key question is if adding a  “virtual network” can be subject to a separate 
subscription (where e.g. different SLAs, pricing, legal conditions etc may 
apply) or if adding a virtual network can only be done by changing the 
subscription to a virtual data center service (which has uniform SLAs, pricing, 
legal conditions etc). According to the framework, the latter appears to apply.

3.     And while we are at it: the claim in draft-maino-nvo3-lisp-cp-01.txt 
that draft-lasserre-nvo3-framework-03.txt has defined key terms such as DC is 
correct, however, it is not the term DC that is used, but the term “data center 
network”. And unfortunately, the term data center network is not defined. For 
example, I am not sure, if the term “data center network” refers to

a.     the underlay network inside the boundaries of a single DC, including its 
capability to create virtual data centers comprising multiple VNs, where each 
VN is confined to the boundary of one DC

b.    the underlay network potentially spanning the boundaries of multiple DC, 
including their capability to create virtual data centers spanning multiple DC, 
and thus VNs spanning multiple DC.

c.     Something else

It should be noted that the definition of the term “virtual data center” 
currently does not specify, if it is confined to one DC or may span multiple DC.

IETF repository.



Filename:  draft-maino-nvo3-lisp-cp

Revision:  01

Title:            LISP Control Plane for Network Virtualization Overlays

Creation date:    2012-09-19

WG ID:            Individual Submission

Number of pages: 19

Abstract:

   The purpose of this draft is to analyze the mapping between the

   Network Virtualization over L3 (NVO3) requirements and the

   capabilities of the Locator/ID Separation Protocol (LISP) control

   plane.  This information is provided as input to the NVO3 analysis of

   the suitability of existing IETF protocols to the NVO3 requirements.
