Asunto: 答复: 答复: [Ibnemo] How to group/reuse definitions


[Yali] Our expressions of new DMZ are similar, except you omit parameter lists. And firewall and l2-group(L2Switch in your expression, I think) are predefined node types, so I omit them.

    A key point/difference is how to express the connection/connectivity between the two nodes. I think resource is a essential element to allow the communication between nodes no matter where it is, that is, if there is not "real" connection between nodes, they will not be connected.

Sorry, but I would distinguish a ‘logical patch panel’ implemented in an Open VirtualSwitch inside a server blade or even inside a data centre supporting SDN, NFV, etc. from a real link (i..e. my second example). Why? Because these connections have no specific characteristics, while a "connection over a cable” has characteristics like Bandwidth etc.


    And what if user wants to assign a bandwidth in this connection? So I am not sure if the "Connect" includes enough information.

The Connect is used when I have no specific requirements. In an example related more to ETSI/NFV, I could see the Connect as the logical connection between Virtual Network Function Components (VNFCs) inside a VNF.

My .02 cents, /PA
