Dear Luis, all Sorry for my delayed response. I am fine with your porposal, thanks for that. As suggested I'd like to propose some text for an annex on performance comparison between both proactive, reactive SIAL and RFC 6224 in terms of amount and length (# of Bytes) of messages exchanged between MN and MAG, and between MAG and LMA, and the impact on expected end-to-end delay (between service stop at start of HO and service resumption at HO completion) for different typical messsage exchange delays on MN-MAG and MAG-LMA path (same for LMA-pMAGand LMA-nMAG). Hope this is what you also had in mind, otherwise please correct me. As a first approach I would assume - 4 msgs with 84 bytes length on MN-MAG and 3 msgs with 64 B on LMA-MAG for RFC 6224, - 2 msgs with 92 bytes length on MN-MAG and 5 msgs with 65.2 B on LMA-MAG for proactive SIAL, - 2 msgs with 92 bytes length on MN-MAG and 5 msgs with 76 B on LMA-MAG for reactive SIAL. (I'll have to check whether those data are still valid since I compiled them some time ago)
Corresponding to your paper (Contreras L. M., Bernardos, C. J., and I. Soto, "RAMS: A Protocol Extension to PMIPv6 for Improving Handover Performance of Multicast Traffic", Journal of Wireless Mobile Networks, Ubiquitous Computing, and Dependable Applications, Vol. 2, No. 2, pp. 67-82, 2011) I would suggest to consider an average MN-MAG delay of 65.3 ms (UTRAN) and the backhaul (MAG-LMA) delay of 5 ms. However for LTE also lower RAN delay of 5 ms could be assumed. Do you think that makes sense?

Mai 2012 16:57 An: [email protected] Betreff: Re: [multimob] I-D Action: draft-ietf-multimob-fast-handover-00.txt Dear colleagues, We have produced the -00 version of the WG draft on fast handover. Some comments received on the list have not been yet addressed so far, but our intention is to include the following material in -01 version once discussed/agreed on the list: .- Hitoshi's comments regarding MLD filter information: we plan to include the MLD filter information on the messages to help the nMAG to get knowledge of the MN's on-going subscription. The original idea of the draft was to optimize (if possible) the information passed among entities by transferring the minimal information to help during the handover process. In our opinion it is worthy to explore that way, but including the MLD filter information can be seen as the regular solution. .- Hitoshi's comment on message format conforming RFC3810: this is linked with the comment above, and it would be addressed, as well. .- Hitoshi's comment on RAMS acronym: we have already changed from RAMS to SIAL = Subscription Information Acquisition through the LMA to avoid confusion with RAMS meaning on the context of the AVT, and to better address the nature of the solution, providing space to further solutions based on MAG to MAG direct communication. .- Dirk's comment on performance evaluation: we are open to include some comparison to RFC6224 as guideline for solution deployment. Apologies if we have left some comment not yet covered. Of course, any new comment is more than welcome. Thanks in advance, Best regards, Luis -----Mensaje original----- De: [email protected] [mailto:[email protected]] En nombre de [email protected] Enviado el: martes, 22 de mayo de 2012 16:30 Para: [email protected] CC: [email protected] Asunto: [multimob] I-D Action: draft-ietf-multimob-fast-handover-00.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Multicast Mobility Working Group of the IETF. Title : PMIPv6 multicast handover optimization by the Subscription Information Acquisition through the LMA (SIAL) Author(s) : Luis M. Contreras Carlos J. Bernardos Ignacio Soto Filename : draft-ietf-multimob-fast-handover-00.txt Pages : 37 Date : 2012-05-22 This document specifies a multicast handover optimization mechanism for Proxy Mobile IPv6 to accelerate the delivery of multicast traffic to mobile nodes after handovers. The mechanism is based on speeding up the acquisition of mobile nodes' active multicast subscriptions information by the mobile access gateways. To do that, extensions to the current Proxy Mobile IPv6 protocol are proposed. These extensions are not only applicable to the base solution for multicast support in Proxy Mobile IPv6, but also can be applied to other solutions envisioned as possible architectural evolutions of it. Furthermore, they are also independent of the role played by the mobile access gateway within the multicast network (either acting as multicast listener discovery proxy or multicast router).
