ABSTRACT:
A computer program product, apparatus and method for providing a performance neutral heartbeat in a computer communication system, the computer program product including a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method including 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.
