Abstract
A system is disclosed for sharing the work load of incoming calls between two computers. The system employs memories recording the total number of calls to be processed and the number to be processed by a particular one of the two computers in a given time period. The first calls received are sent to the one computer. When the number of calls actually processed by the one computer has been received the following calls are sent to the second computer to be processed. When the total number to be processed is actually reached, the system is reset to its initial state and the cycle is repeated.
Claims2
A call load sharing apparatus for a communications system in which said apparatus processes the completion of calls through the system, said apparatus including a first processor for processing a first plurality of calls through said system and a second processor for processing through said system calls other than said first plurality of calls, said apparatus including a first memory for storing a predetermined first number indicative of the calls which are to be processed through said system, a second memory for storing a lesser number, the lesser number representing the number of said first plurality of calls to be processed by said first processor, scanning means receptive of calls from the system for initiating the processing of calls by said first processor, a first counter responsive to all calls received by the scanning means for producing a first count representing a total of the calls received for processing, a second counter responsive to calls being processed by said first processor for producing a second count, a comparator for comparing the second count against the number stored in said second memory, said second comparator responsive to an equality between said second count and the second number for producing an output signal, and a control unit responsive to the output signal for causing subsequent calls received by said scanning means to be processed by said second processor.
