Abstract
A data stream is created for moving data from a source to a target in accordance with a stream protocol defined by controlling stream protocol control blocks (SPCBs) created from a predefined source SPCB and a predefined target SPCB. The controlling SPCBs include information establishing a plurality of data buffers that are used to efficiently stream or transfer data on a real-time basis. The controlling SPCBs are formed by a process of negotiation in which differences between the source and target SPCBs are reconciled in accordance with rules of negotiation. Once the data stream is created, it is then started by the application program and data is streamed until an end of stream is reached.
