This case outlines corrections to the LDC specification approved under ARC case number 2006/140. The major changes are document corrections and addition of streaming capability as part of the reliable protocol. The project team has been using the below mentioned changes in its implementation. This case is to document these changes. Here are the details. 1. The reliable mode now includes data streaming to improve performance by allocating large Tx/Rx queues for data transfer. 2. The mode number of 0x2 was previously used for reliable mode, and is now replaced with mode number of 0x3. Mode value of 0x2 is now reserved and should not be used by any client. The mode value of 0x3 is used to support both older and newer clients in the implementation. The Packet Envelope (Word 0, Bits 24-31) field in a RTS or RTR message also now specifies mode 3 for reliable mode since mode 2 is marked as reserved. 3. Correction to both unreliable and reliable datagram. The original session id is now a sequence ID. The original sequence ID field is now marked as reserved field. The Session IDs are not used as the HV provides the ability to detect session resets via asynchronous notifications. All clients have been using the new datagram structures for a while. This case correct the documentation error. 4. Changes through out the document related to above mentioned changes. I have copied both the new specification and a PDF of diffs generated from start office document source in the materials directory. An interface table is also in the materials directory, http://sac.sfbay.sun.com/Archives/CaseLog/arc/FWARC/2006/571/materials/ Thanks. -- Hitendra Zhangada ============================================= SPS Common SW Features Engineering Systems Group, Sun Microsystems, Inc.
