Tony, Thanks for this write-up. Very helpful for those of us unable to be on the call. Adrian From: CASM [mailto:casm-bounces@ietf.org] On Behalf Of Pengtao (Tony) Sent: 23 March 2017 02:19 To: casm@ietf.org Subject: [Casm] minutes of CASM meeting on March 22 Hi all, Please find the minutes of yesterday’s WebEx meeting below. Regards, 彭韬 Tao PENG (Tony), Ph.D. Senior Researcher Huawei Technologies Co.,Ltd dr.pengtao@huawei.com www.linkedin.com/in/tao-peng Minutes CASM 2017/3/22 Host: Marc Blanchet Attendees: Agustin Formoso Benoit Claise Telecom Italia: Giuseppe Fioccola ZDNS: Declan Ma China Telecom: Chen Li, Chongfeng Xie China Unicom: Ying Cheng Huawei: (David) Weiping XU, Will Liu, (Tony) Marc: it is not yet clear about the scope and deliverables. Li explained the draft “casm-pool-management-arch” - address management procedure and showed slides to explain the architecture. Marc: Architecture in Figure 1 seems from Rakesh, which is broader. We need to get things converged. Benoit: what you explained seems to be a subset. Ma: you may also consider the RPKI system (Resource Public Key Infrastructure). After the prefixes are allocated, certificates need to be generated. This should connect with IPAM. Benoit: what are the building blocks that you touch in the figure (slide 2)? Xie: the south bound of ASMS system should be defined and standardized. A portal may be used for address configuration. A north bound interface could be defined. Benoit: what is the flow among these entities (DHCP message/Yang?). Xie: if we deploy centralized interface, there is only interaction between BNG and our management server. Currently, there is no management server; the configuration is done on BNG. Benoit: I see disconnection between requirement and current implementation, which is a subset. Xie: this architecture can cover several use cases. For example, it can be used on DHCP configuration, IPTV. Benoit: do these people want to work on the full scope, or the scope is to only have BNG interaction? Xie: address allocation in the cloud may be considered in the architecture. It is very important; some automatic mechanisms can be used. Giuseppe: dynamic service creation could be an important use case. The application is crucial. Liu: I was looking at the draft from Rakesh. Chen Li addressed most of the scenarios in Rakesh’s draft. Benoit: how the use cases are covered by your draft? What is the current interaction flow from operator to network elements (BNG/DHCP…)? Do we have meeting agenda? TODO: 1, identify the details on south/north bound interfaces 2, show how the use cases are covered 3, consider the interaction flow of Address Space Management & Control 4, chairs decide the topics during BoF 5, start a thread to find a timeslot for a meeting on Sunday for better preparation
