Dear all, Let me inform you that the IPPROV <https://trac.tools.ietf.org/bof/trac/#OperationsandManagement>BoF was declined by the IESG/IAB. Even if the IETF discussion started three IETF meetings ago (draft-sun-i2apm-address-pool-management-arch <http://tools.ietf.org/html/draft-sun-i2apm-address-pool-management-arch> and draft-sun-i2apm-address-pool-management-yang <http://tools.ietf.org/html/draft-sun-i2apm-address-pool-management-yang> were presented at IETF 94 in OPSAWG), this BoF request came as a surprise, on the last day just before the BoF submission deadline. As such, it didn't generate much (visible) discussion among the community. draft-sun-i2apm-address-pool-management-yang <http://tools.ietf.org/html/draft-sun-i2apm-address-pool-management-yang> is about a YANG model for IPv4 management. Coming from an operator, it was specifically welcome, and OPSAWG seems like the perfect WG. This document describes an mechanism for a standard, programmatic interface for address pool management. With the remaining IPv4 address becoming more and more scattered, it is complicated to manually configure the address pools on lots of Broadband Network Gateways(BNGs) for operators. By introducing SDN/NFV in BNG, the address pools can be allocatedin a centralized way. It will not only simplify the address management for operators, but also improve the utilization efficiency of the address pool. One issue is that IPAM use cases involve many different NMS/OSS different systems: IPAM, DHCP, DNS, Orchestrator, CMTS, Router, Firewall. All these different key players need to agree on these protocol exchanges/APIs/data models. Btw, I consider YANG models as APIs, as the APIs can be deduced from the models. While we understand that any operators have this issue today and would like to have a simplified solution for address pool management, do we have all the key players from the NMS/OSS ecosystems involved, and a willingness to implement what would become a standard? On top of that, some integration happens today, as those independent different systems have some embedded automation and event mechanisms. Today, the controller/orchestrator will take whatever is APIs are available. Granted, the integration is certainly clean and standardized, but aren't we risking to be late if a standard is approved in 1.5 years? Or maybe this effort should be supported in opensource, with de facto solutions? Looking at the scope, it seems that it extended along the time: From IPv4 address management to IPv6 (well, obviously, we have the same issues with IPv6) to bandwidth and services management, along with some "possible protocol work", as mentioned in the BoF description. A well defined scope is a plus for a BoF request. This BoF would be have benefited from some more preparation and preliminary discussions with the community and the ADs. The connection with ANIMA, as discovered on the mailing list, is certainly a prove of that. Finally, not having a BoF is certainly not a reason for the community to stop organizing itself. Regards, Benoit
