Hi Chen Li,

Okay, thanks.
Are you then  planning to use NETCONF/YANG data models for these interfaces?

Best regards,
Georgios

Hi Chen Li,



From what I understand, by using CASM you would like to enhance the operation of IPAM (IP Address Space Management) tools by defining standardized interfaces for a centralized management of IP addresses.



Are you planning to work in IETF on specifying both the interfaces that are mentioned in the draft?

•         CASM App-facing Interface

•         CASM device-facing Interface

If that will be the case are you then planning to use NETCONF/YANG data models?



Are you also willing to prioritize any of these two interfaces?

 <Answer> Yes. Both interfaces of the Coordinator are in the working scope. We think that they all play an important role. As stated in the architecture, the Coordinator should cooperate with various CASM apps to implement address management, operation and maintenance. Similarly, it must cooperate with various network devices through device-facing interface to realize the shared use of IP address resources.



It might be possible that CASM could work use in addition to the address management attributes also on other attributes, e.g., billing. Are you also willing to consider other attributes  than address management attributes in this work?

<Answer> We want to consider the various attribute, the CASM architecture is flexible to supports centralized management of various resources. Currently, IP address is the primary initial focus, and other attributes are considered in the future.

Best regards,

Georgios

Hi all,



We have updated the new version of I-D, draft-li-opsawg-address-pool-management-arch-01.txt, the revision was made based on the comments raised in London meeting,

Telecom Italia also provided a new use case afterwards, which was also included in this new draft.



Here is the  link of the draft .  wish for your comments, Thanks.

Best Regards,



Chen Li
