[MMUSIC] BUNDLE TEXT: ICE Procedures (18.6)

[Christer Holmberg <[e-mail]>]

Hi,

I did some updates (mostly editorial) to the BUNDLE ICE Procedures section.

So, when reviewing BUNDLE-04, for the ICE parts, please use the text below as base :)

Regards,

Christer

8.  Usage With ICE

8.1.  General

   This section describes how to use the BUNDLE mechanism together with
   the Interactive Connectivity Establishment (ICE) mechanism [RFC5245].

8.2.  ICE Candidates

8.2.1.  Offerer Procedures

   When an ICE-enabled Offerer generates an SDP Offer, with a BUNDLE
   group, the Offerer MUST assign ICE candidates [RFC5245] to each "m="
   line in the BUNDLE group.

   If the Offerer assigns unique addresses to each "m=" line in the
   BUNDLE group, the Offerer MUST assign assign unique ICE candidate
   values to each "m=" line in the BUNDLE group.  The Offerer MUST NOT
   assign the same ICE candidate values to "m=" lines outside the BUNDLE
   group, or to "m=" lines in another BUNDLE group.

   If the Offerer assigns the BUNDLE address to each "m=" line in the
   BUNDLE group, the Offerer MUST assign assign identical ICE candidate
   values to each "m=" line in the BUNDLE group.  The Offerer MUST NOT
   assign the same ICE candidate values to "m=" lines outside the BUNDLE
   group, or to "m=" lines in another BUNDLE group.

8.2.2.  Answerer Procedures

   When an ICE-enabled Answerer generates an SDP Answer, with a BUNDLE
   group, the Answerer MUST assign ICE candidates to each "m=" line in
   the BUNDLE group.  The Answerer MUST assign identical ICE candidate
   values to each "m=" line in the BUNDLE group.  The Answerer MUST NOT
   assign the same ICE candidate values to "m=" lines outside the BUNDLE
   group, or to "m=" lines in another BUNDLE group.

8.3.  ICE Connectivity Checks

   Once a BUNDLE address has been selected for the Offerer and the
   Answerer, it is RECOMMENDED to perform ICE connectivity checks and
   keep-alives [RFC5245] for the whole BUNDLE group, rather than for
   each individual "m=" line in the BUNDLE group.
