August 3, 2007 IEEE P1722 AVBTP Working Group Contribution 4 Proposal Summary •Provide a fragmentation/reassembly service based on an integral number of quadlets •Add one additional quadlet to AVBTP header for all stream data frames •Standardize use of packet length field to use in Bartky Networks www.bartky.net •Standardize use of packet length field to use in conjunction with fragmentation and reassembly algorithms (e.g. used as sanity check for reassembly) –Use 1394 isochronous packet byte length field from previous proposals August 3, 2007 IEEE P1722 AVBTP Working Group Contribution 5 Proposal Summary • Add the following new fields: – Fragment Length (quadlet count) – Fragment Control (First and Last bits) – Stream Sequence (quadlet count) • Reuse the 1394 based packet length field, but standardize for all stream types. • Mandate “smart fragmentation”for cases such as 61883 Bartky Networks www.bartky.net • Mandate “smart fragmentation”for cases such as 61883 where packets are to be fragmented on source packet boundaries – Fragmentation rules passed to on a per stream basis • Per stream needed anyway to handle sequence number control • Allow for delivery of received pipelined fragments and/or incomplete reassembled packets at AVBTP to upper layer.

I have updated the GEN Comment Spreadsheet: https://mentor.ieee.org/802.11/dcn/12/11-12-1394-01-000m-gen-adhoc-preballot-comment-collection-resolutions.xlsx   The Tab for Vinko's set of comments is now labeled GEN-1297 Dorothy will have a motion prepared for this morning that accepts the resolution for GEN Motion A (Comments from Sept), and GEN-1297 (Vinko's Comments).  

Will the RAC make the request that IEEE Standard 1394 be modified to use EUI-48?
