Detailed Description

IPv4 Deduplication Performance Test.

This test case sets up a fully connected network of 10 nodes. Each node transmits 2 packets / second for about 20 seconds. Packets are relayed from every receiver. The test outputs the number of events that have been processed during the course of the simulation. Test runtime is also a metric.

The de-duplication cache entry expiration algorithm has evolved from an event-per-expiry (EPE) algorithm to a periodic event, batch purge (PBP) algorithm. The current metrics are taken from tests on the development box. Periodic batch purge period defaults to 1s.
