Method of dynamically adjusting NCP program memory allocation of SNA network

摘要

A method in accordance with the invention is implemented via a novel computer program referred to for convenience as NEWPROG. NEWPROG resides (executes) in one or more communication controllers on a SNA network "front end" processor for the NCP executing in that controller. NEWPROG makes it possible for the NCP memory management routines to dynamically increase the number of control blocks by scavenging available NCP memory. Those control blocks created by NEWPROG may also be deleted. Use of the method permits the NCP to improve its resource availability by generating user requested control block structures as needed (within total NCP load memory limitations).
