Re: [Ibnemo] [Nfvrg] 答复: Defining a Common Model for intent

["Susan Hares" <[e-mail]>]

Yinben and Pedro:

 

I agree you that the role of the user is more accurate than layer, but could you provide examples at lower layers.  At the user level, a user can signal intent to create a connection from Boston Office to Denver office across the whole network.

Pedro,

 

Agree with you. 

According to your example, I think ‘intent’ should be classified by user’s role  more accuracy than by layer.

Sometime users’s role have layer relationship, but not always same layer relationship.

 

Best regards,

Yinben

Hi,

 

A small clarification proposal for draft  <https://datatracker.ietf.org/doc/draft-xia-ibnemo-icim/> https://datatracker.ietf.org/doc/draft-xia-ibnemo-icim/ .

 

In section 2.4, I would leave the following as a paragraph

For example, in the network area the intent of end-users could be
safe connectivity between two sites which a technology independent
and device independent requirement. For business-based network
designers, the network connectivity can be selected which is device-
independent but technology specific. An example of the business-based
technology is the L3VPN. 
And change:
For network administrators, intent can be
specific operations on a set of devices such as configuring IP
addresses on network servers in a data center.

To

 

For network administrators, intent can be <new>defining a network topology like a router connected to a firewall, connected to a load balancer and this to two L2 networks where WWW servers sit or specifying the</new> operations on a set of devices such as configuring IP addresses on network servers in a data center.
 
Rationale behind this is again, that intent should be anything that is invariant and that expresses what a network operator/administrator may need to do, as opposed to how he would do that, i.e. The router is a HW device from vendor X or a virtual machine running a specific routing daemon over a given data-path implementation.
Best, /PA
