Abstract:
A computer implemented method for providing status information in a system comprised of multiple components, comprising:receiving, at a first processor node, status information indicating a state of a system component; generating a status message, with the first processor node, indicating the state of the system component; transmitting, with the first processor node, the status message to a second processor node; determining, with the second processor node, whether the status message has a first sequence number that is consecutive with respect to a last received status message having a second sequence number; when it is determined that the first sequence number of the status message is not consecutive, determining, with the second processor node, that a previously generated status message having a third sequence number was not received by the second processor node; and when it is determined that the first sequence number of the status message is consecutive, updating, with the second processor node, status information maintained by the second processor node with the state of the system component indicated in the status message; and returning status information maintained by the second processor node to a request for status.
