Dear MOPS Hope the IETF meeting going well on your end. Although I might not have the slot to present the updated version of the contribution again in the MOPS session, I want to bring your attention and solicit more comments from you through our email list. Here is the summary of feedbacks from the last meeting: * The comments are mainly related to how to reveal the characteristics of microblocks contained in the packet to the network and implement the selective packet dropping at packet level. * For the comment from Jake regarding DiffServ could be applied at the packet level, I would like the help to find the reference(s) about it. After I confirm it is doable, I will update the draft accordingly by removing this shortcoming of DiffServ, but indicating DiffServ could be one implementation method. * Very glad that the concept is very well received: it is beneficial to improve QoE of video streaming by reducing the packet dropping granularity from current traffic class level to the individual packet level, even portions within the packet. * Yes, exactly, we need such information of whether this packet is significant or not to be revealed to the network nodes. For example, an API could be implemented to input such information or metadata from the application. which might be mapped to IPv6 extension header, IPv4 options or a dedicated metadata field in the IP header. For the updated version, I mainly added more discussion on the important characteristics of MPEG video packets that would affect the packet significance and the requirements that need to be satisfied by both video applications and network side. https://datatracker.ietf.org/doc/draft-dong-usecase-packet-significance-diff/01/ I attached some new slides for your reference. I would like to receive more suggestions on how to improve the draft and how to move forward. Thanks for your attention during this busy week. Lijun
