Patent ID: 8051165

Claim:
A mediation method for processing event records by means of a mediation system comprising at least two independent processing nodes and at least one node manager, the method comprising the following computer-implemented steps: receiving the event records from a communications network, processing a content and/or a quantity of the event records in the independent processing nodes and keeping counts relating to the processed event records in audit counters in the independent nodes, wherein said processing is performed by operating each of the independent nodes according to individual settings thereof and independently of the other independent nodes of the mediation system, reporting the counts in the audit counters to the node manager, and monitoring the functioning of the independent nodes by the node manager, wherein the monitoring includes checking whether the counts of the audit counters, including the counts of the event records processed, provided by the independent nodes match, in order to ensure that none of the event records is lost during processing, wherein the audit counters include: a counter for the event records output from the node, a counter for the event records input to the node, a counter for the event records residing in the node, a counter for the event records split in the node, a counter for the event records duplicated in the node, a counter for the event records generated in the node, a counter for the event records filtered in the node, a counter for the event records discarded in the node, and a counter for the event records aggregated/correlated in the node.
