• Peer to Peer Data Transport Specification - PPDT_r12.pdf - Updated June. 27, 2000

In the area of device discovery and enumeration, the group had identified requirements which were not addressed in existing standards (IEEE Std. 1212-1994). The 1394 PWG applied for a PAR to the IEEE MSC for this effort. Instead of a new effort, the MSC recommended these efforts take place as part of the IEEE P1212r revision effort. Some members of the 1394 PWG participated in that effort. The IEEE P1212r working group has completed work on the revision and it currently headed to ballot. More information is available on the IEEE P1212r web site.

Many discussions and proposals were considered for transport solutions. Other efforts were looking at 'lighter weight' solutions that were focused on direct links between data producers and consumers. The 1394 PWG was looking for a reliable solution that could be used across multiple device classes. Consensus was reached that a transport solution should be able to support a 'sockets' type of API and would make efficient use of the underlying link. After research and discussion, a decision was made to use Serial Bus Protocol 2 (ANSI NCITS 325-1998) for the underlying transport. The major focus of the WG has been the development of a byte stream oriented command set and communication profile for the SBP-2 transport that could support connections to multiple services over a single SBP-2 login.

In October of 1999, the 1394 PWG presented a Project Authorization Request (PAR) to the IEEE Microprocessor Standards Committee (MSC) to standardize this effort. The MSC approved the PAR and passed it on to the IEEE New Standards Committee (NesCom) for review at the January 2000 meeting. NesCom approved the PAR and the formation of the P1394.3 Working Group.

• DRAFT documents represent the current sections of the IEEE-P1394.3 standard that have been agreed to in principle, documented and or reviewed by this working group. Official document names are assigned by the WG Chair.

• Proposal documents represent submissions to the working group that may or may not be included in the final results published by this group. Refer to the meeting minutes to understand the current status of these documents.

  The naming convention used represents a compact encoding that provides year, document number and revision information.

  <Year>-<Document><Revision>.pdf

  • <Year> - Two digit representation (i.e. 1999 - 99, 2000 - 00, 2001 - 01, etc.)
    
  • <Document> - Three digit sequential representation (001, 002, 003, etc.)
    
  • <Revision> - Single digit sequential representation preceded by the letter 'r'(r0, r1, r2, etc.)
