scope:

This is a full-use standard whose scope is the definition of a peer-to-peer data transport (PPDT) protocol between Serial Bus devices that implement ANSI INCITS 325-1998¹ .The facilities specified include, but are not limited to, the following:

- Device and service discovery. PPDT devices may use uniform discovery procedures to locate other PPDT devices on the same bus.These procedures are extensible to an interconnected net of buses, when specified by IEEE P1394.1™ [B2 ]. Once other PPDT devices are identified, facilities are provided to permit client applications to discover services;

- Self-configurable (plug and play) binding of device drivers to PPDT devices in a dynamic environment where users are free to insert and remove devices at will; and

- Connection management. A PPDT device [either a Serial Bus Protocol 2 (SBP-2) initiator or target ] may establish and manage uni-or bi-directional connections for data transfer with other PPDT devices.The connections may be blocking or nonblocking, dependent upon application requirements, and operate independently of each other.

Although this standard was developed by printer and scanner experts, it is relevant o any application that requires efficient, peer-to-peer transport of data between SBP-2 devices.
