Abstract
A retrieval system and method which allows a computer system to adjust the data retrieval start times of the data retrieval requests from the different users in order to achieve overall system objectives. Each user is assigned a percentage availability which then determines a factor for all of the applications run by that user. This factor is associated with each request for data retrieval from any application. For any given batch of data requests there is calculated a start time for each data request, with the start time dependent upon the assigned factor. The start times from all users for that batch are then ordered in accordance with the calculated start times. The system will reorder the start times when efficient operation requires such reordering.
Claims19
The method of operating a system where multiple users must from time to time access a bandwidth limited device and wherein each user desires to have a certain percentage of access to said device, the method comprising the steps of:
- having assigned to each user a percentage of access time relative to the other system users;
- from time to time accepting from said users requests for access to said device, and
- determining for each such request a start time for such request, the start time being dependent upon the assigned percentage of access for the user from whom the request was accepted.
A system where multiple users must from time to time access a bandwidth limited device and wherein each user desires to have a certain percentage of access to said device, the system comprising:
- apparatus for assigning to each user a percentage of access time relative to other system users;
- apparatus operative from time to time for accepting from said users requests for access to said device, and
- apparatus for determining for each such request a start time for such request, the start time being dependent upon the assigned percentage of access for the user from whom the request was accepted.
