Hi Thomas, Matthias, Rajeev, Gorry,
I have read draft-schmidt-multimob-fmipv6-pfmipv6-multicast-06 and I have some comments: Comment_1: The draft is useful since it is providing a solution for seamless and fast handover for multicast applications by extending existing seamless and fast handover solutions used for unicast applications, which are the Mobile IPv6 Fast Handovers (FMIPv6) specified in RFC5568 and the Fast Handovers for Proxy Mobile IPv6 (PFMIPv6) specified in RFC5949. Comment_2: A motivation section is missing from the draft. In my opinion it is very useful to include such section in this draft. In particular, this draft mentions that a seamless and fast handover solutions is needed for multicast applications like IPTV. Other scenarios and applications that should probably be mentioned and that will make use of such solutions are the Public Protection and Disaster Relief (PPDR) scenarios & application types, where mobile multicast communications need to be supported between members of rescue teams, police officers, fire brigade teams, paramedic teams, command control offices in order to support the protection and health of citizens. In particular three main PPDR scenarios & application types could be distinguished: 1) City security scenario: that can be used to support the day to day safety and security of citizens. 2) Disaster recovery scenario that deals with the protection of people and rescue teams during large scale natural or man-made disasters, like flooding, earth quakes and nuclear disasters. 3) Temporary Protection PPDR scenario that deals with safety and security of citizens visiting large planned events like football matches, pop concerts and protest demonstrations. Comment_3: The draft is not clear about the main differences between this draft and draft-ietf-multimob-fast-handover-01. From what I understood after reading both drafts: o) draft-ietf-multimob-fast-handover-01 focuses on the extension of the Proxy Mobile IPv6 (PMIPv6) RFC5213, and the “Base deployment for multicast listener support in Proxy Mobile IPv6 (PMIPv6) Domain” RFC6224, to achieve fast handover for mobile multicast applications, while: o) draft-schmidt-multimob-fmipv6-pfmipv6-multicast-06 focuses on the extensions of Mobile IPv6 Fast Handovers (FMIPv6) specified in RFC5568 and the Fast Handovers for Peoxy Mobile IPv6 (PFMIPv6) specified in RFC5949 to achieve fast handover for mobile multicast applications. Can you please elaborate? Best regards, Georgios _______________________________________________ multimob mailing list [email protected] https://www.ietf.org/mailman/listinfo/multimob
