Abstract (Summary)

This standard specifies a connection-oriented data transfer protocol supporting flow-controlled Read and Write sequences and non-flow-controlled, persistent-memory Put, Get and FetchOp sequences. For all sequences, small control messages are used to pre-allocate buffers at the data Destination before the data movement begins, thus allowing the data to be moved immediately from the physical network into the end deviceís memory.

The control and data messages may use different physical media or may share a single physical medium.

Procedures are provided for moving data over the High-Performance Parallel Interface (HIPPI) and other media.
 

Audience

Purchasing users: can require conformance to the standard in order to insure interoperability among applications software, driver software, host operating system software, and adapter hardware to obtain maximum portability and system independence.

System and Adapter Vendors: can build system using Scheduled Transfer to provide efficient data movement.
 

Scope (Intention)

Scheduled Transfer is a generically applicable transport layer protocol suitable for moving data on any network where efficiency, high speed, and low latency are desired.
