Abstract

Allocation of unused storage into a buffer pool increases the throughput of a receiving station in a system network architecture (SNA) communication environment and eliminates the definition of an alternate communication configuration. The pacing mechanism of SNA controls receiving of data frames and signals readiness for accepting the next group as soon as the required number of buffers is available. At the same time the content of the remaining buffers is being processed so that an overlapping performance of data processing and data transmission is obtained. Within an SNA communications network various protocol mechanisms exist to regulate the flow of data. Control of the data link is defined by the Synchronous Data Link Control (SDLC) protocol.
