Hi,

Based on the comments from Christian, I suggest the following new text for BUNDLE:

-----------------------------

6.2.2.  Connection Data (c=)

   The "c=" line nettype value [RFC4566] associated with each "m=" line
   within a BUNDLE group MUST be 'IN'.

   The "c=" line addrtype value [RFC4566] associated with each "m=" line
   within a BUNDLE group MUST be 'IP4' or 'IP6'.  The same value MUST be
   associated with each "m=" line within a BUNDLE group.

   NOTE: Extensions to this specification can specify usage of the
   BUNDLE mechanism for other nettype and addrtype values than the ones
   listed above.

-----------------------------

Regards,

Christer

Aihe: Re: [MMUSIC] Draft new version: draft-ietf-mmusic-sdp-bundle-negotiation-05

Hello Christer,

The SDP grouping mechanism can be applied to different nettype/addrtypes. The BUNDLE draft appears to define behaviour related only to the nettype=IN and addrtypes=IPv4/IPv6. i.e. section 2 defines BUNDLE terminology based on IP.

Is there an intention that the BUNDLE mechanism is only used for the above net and addrtypes? If so should it be mentioned somewhere in the applicability statement?

Regards, Christian
