Hello All,

Juan-Carlos and I worked on this last paragraph in section 6. We believe that section 6 is OK
with the following change: 

1) Replace this paragraph:

It is mandatory the use of UDP and TCP as default transport
   mechanisms implemented in the server side.  The MN SHOULD discover
   server transport options.  The MN can choose one of the mandated
   transport protocols.  It is optional the use of SCTP both for server
   side and MN side.


with this one:

The server side MUST support both UDP and TCP for MIH transport, and the MN MAY support either UDP or TCP. 
Additionally, the server and MN MAY support additional transport mechanisms.
The MN SHOULD discover the server's preferred transport mechanism to use in each service as defined in [I-D.bajko-mos-dns-discovery].



2) Add the following sentence at the end of last paragraph of section 6.3:

Additionally, instead of retransmitting an unacknowledged message, the MIH may choose to update the information and transmit a new message.



3) Add the following reference to the end of first sentence of section 6:

Once the Mobility Services have been discovered, MIH peers MAY
   exchange information over TCP, UDP or any other transport supported
   by both the server and client, as described in [I-D.draft-rahman-
mipshop-mih-transport].

4) Add the following reference

[I-D.draft-rahman-mipshop-mih-transport]Rahman, A., Olvera-Hernandez, U., Zuniga, JC., Wafta, M., and Kim,
H.W., “Transport of Media Independent Handover Messages Over IP,” draft-rahmanmipshop-mih-transport-03 (work in progress), July 2007.

Any comments?

-Nada and Juan-Carlos
