How We Did It

Our test environment consisted of a Netcom Systems' SmartBits 6000 chassis with four LAN 6,201-byte modules, each module containing two 1000BaseSX ports with SC connectors. The SmartBits chassis was running OS 1.4.15 with firmware Version 2.1.24. You can visit for more information on this testing product. Autonegotiation on all ports was enabled by default with flow control turned off. All frame loss and latency tests were performed using Netcom's SmartFlow Version 1.12.1. This software allows you to conduct throughput and latency tests in different configurations, and provides tools for analyzing and reporting the test data. The error test was conducted with Netcom's SmartWindow.
