Distributed platform for testing filtering rules
InactiveUS7685271B1Quickly and efficiently testEfficient and quick testMemory loss protectionError detection/correctionTraffic volumeTraffic capacity
A distributed testing platform tests network traffic filtering rules. A control point receives a network traffic filtering rule and test parameters describing how to test the rule. The control point distributes the rule and parameters to a plurality of testing nodes. The testing nodes are located on a network at locations where they receive a variety of different network traffic. The testing nodes test the rule against traffic received by the nodes according to the test parameters. The traffic can include real-time traffic and corpora of traffic designed to test different types of rules. The testing nodes return test results describing the testing to the control point. The control point analyzes the test results to determine the accuracy and performance of the rule.
