The Reserved Availability Method is a software mechanism for allocating a non‐sharable machine resource such as multi‐access ports according to different user catagories and priorities. The method avoids the queuing of user requests for allocation. Instead, some of the available resources are reserved for allocation to high‐priority, or particular categories of users. The resources reserved vary with machine usage in order to optimize machine utilization with user demand. The method is applied to the partitioning of a machine's ports between different user groups, and to access according to user priority.
