SAMRG (Scalable Adaptive Multicast) IETF-79 Chairs: John buford and Thomas Schmidt Note-taker: Matthias Waehlisch 1. Introduction by Chairs 2. Presentation "A Common API for Transparent Hybrid Multicast - Update and Report on Implementation Experiences draft-waehlisch-sam-common-api-04 (Matthias) Thoerless: The goal of the implementation is to provide ASM service that is dynamically instantiated via native or overlay multicast, correct? Matthias: Yes, but SSM is also supported Thoerless: Is there support for ASM over SSM? Matthias: No, but tp come in future work Thomas: Which implementation experiences had feedback for API design? Matthias: Some API calls had been changed. 3. Presentation Labelcast Protocol draft-sunzhigang-sam-labelcast (Sun) Thomas: You use IP-Multicast addresses at the IP layer. How do you assure that packets are delivered to switching nodes without interference with IP-Layer multicast routing activities? Sun: IP-layer transmission needs to be defined Thoerless: What is the analysisis of the problem you are trying to solve? Sun: this is a project for IPTV with China Telecom Thoerless: What would not work with existing protocols and technologies of today? Sun: Monitoring of intermediate distribution nodes, important for IPTV & service quality assurance Thoerless: Why not use RTP? Sun: RTP is not part of the network stack, applications do not support point-to-multipoint distribution Wang: What is the label distribution mode: centralized or distributed? Sun: Centralized. 4. Presentation CERNET IPv6 multicast design and deployment (Xing) Thoerless: Does your access grid support IPv6 + SSM? Xing: Only ASM Thoerless: What are the main IPv6 hinderences - IPv6-supporting Apps or the campus routing? Xing: Continued use of IPv4 is just convenient, people don't care. Thoerless: How many IPv6-enabled campuses do you have? Xing: 200 out of 2.000 Thoerless: Is multicast translation specified in IVI? Xing: Not yet Thoerless: Do you want to propose this? Xing: Yes, together with Stig in Behave. Thomas: Are your ASM/SSM gateways self-implemented or standard components? Xing: Self-implemented, no standard components available yet. Stig: I would like to hear more details on technical specifications in mboned Xing: The gateway developer is here, you can ask more detailed questions to him Thomas: Should take additional information to the list 5. Presentation Design Updates for a RELOAD Usage for Distributed Conference Control (DisCo) - draft-knauf-p2psip-disco-00 (Thomas on behalf of Gabriel) 6. Presentation Document status (Thomas) Thomas: Finish RG adoption call for common-Api draft? Thoerless: Nothing agains adoption, just wondering wheter it might interfere with NBS activities Thomas: API specifications should then be broutht into IETF in a revised status Thomas: Transport approaches - shouldn't transport people go for a problem statement / requirements analysis? Sun: Yes, can work on a problem statement Thomas: Should be taken to list to include other transport activities Closing of the meeting
