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.
