I've submitted a revision of my draft, draft-worley-sdp-bundle-03. The proposed bundling mechanism is unchanged (although it will need to be improved, based on the feedback I've received). The useful part of the new version is a draft of a design feature comparison chart for the current bundling proposals. (6 that I've found so far!) The chart can be found at http://tools.ietf.org/html/draft-worley-sdp-bundle-03#section-7 (I'd welcome any corrections or additions to the chart.) The entire draft is at http://tools.ietf.org/html/draft-worley-sdp-bundle-03 Here is a copy of the chart itself (more detailed notes in the draft itself): 7. Design Features and Comparison Key: x = feature present in proposal - = feature not present in proposal . = feature not discussed in proposal N/A = feature is not relevant because of another feature choice worley-sdp-bundle-03 (KUMQUAT) | ietf-mmusic-sdp-bundle-negotiation-03 (BUNDLE) | | holmberg-mmusic-sdp-mmt-negotiation-00 (MMT) | | | alvestrand-one-rtp-02 (TOGETHER) | | | | ejzak-mmusic-bundle-alternatives-00 | | | | | Roach alternative 1a | | | | | |(roach-mmusic-mlines-00) | | | | | | Roach alternative 1b | | | | | | | Roach alternative 2 | | | | | | | | westerlund-avtcore- | | | | | | | | |transport-multiplexing-04 | | | | | | | | |(SHIM) V V V V V V V V V MD grouping: one - - - - - - x - - per type - - - - - x - - - none x x x x x - - x x Separate bundle MD: no - x - x x x x x x m=anymedia - - x - - - - - - m=audio x - - - - - - - - m=multipart - - - - - - - - - Ports in constituent MDs in offer: N/A - - - - - x x - - same - - - x x - - x x different - x x - x - - - - null x - - - - - - - - Immediate update: none - - x x x x x x x for support - x - - - - - - - for compat. x - - - - - - - - Constituent MD ports after establishment: N/A - - - - - x x - - same - x - x - - - x x different - - - - - - - - - null - - - - - - - - - rejected x - x - x - - - - Bundle MD payload types: N/A - - - - - x x - - one MD - x - x . - - x x all MDs - - x - . - - - - encap. x - - - . - - - - Constituent MD payload types: N/A - - - - - x x - - overlapping x - - - . - - x x distinct - x x x . - - - - Demultiplexing based on: N/A - - - - - x x - - PT - x x x . - - - - encap. x - - - . - - x x Rejection of bundle MD based on: N/A - x - x x x x x x media type - - x - - - - - - codec x - - - - - - - - Dale
