PERFORMANCE NEUTRAL HEARTBEAT FOR A MULTI-TASKING MULTI-PROCESSOR ENVIRONMENT
First Claim
1. A computer program product for providing a performance neutral heartbeat in a computer communication system, the computer program product comprising:
- a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising;
maintaining a send flag;
maintaining a receive flag;
determining that a heartbeat timer has activated;
checking a state of the send flag to determine if packets have been sent since a prior heartbeat timer activation; and
checking a state of the receive flag to determine if packets have been received since a prior heartbeat timer activation.
