Re: [16NG] WGLC: draft-ietf-16ng-ip-over-ethernet-over-802.16-02

["Jongtaek Oh" <[e-mail]>]

I have some comment about the draft-ietf-16ng-ip-over-ethernet-over-802.16-02,
especially for broadcasting and multicasting issue.

1. Firstly, it describes the functionality of IEEE 802.16 network for MBS services, very pessimistically.
    As it mentioned, the specification and technology for MBS is not perfect. But it is under developing by NWG of WiMax forum,
    and the broadcasting and/or multicasting in the radio link could be possible, not impossible.
    This draft is for standard RFC, not for informative RFC, so only specification related matters must be defined in the draft
    and leave the room for new technology can come in.

2. MBS service is important for network operators and service providers to compete with the other cellular networks.
    For example, 3GPP Release99 can broadcast messages using cell broadcasting technology.
    WiMax forum is developing MCBCS related technologies and specifications which deals with the solution against the problems the appendix A cited.
    For example, the unicasting or the broadcasting methods are to be decided at the BS or AR according to the number of users in the cell.
    If all the IETF documents exclude the possibility of broadcasting and multicasting transmission method, then they could be useless to the WiMax industry.

In conclusion, I suggest to remove all the sentences which state the negative respects of  multicast/broadcast for 802.16 network including Appendix A.
