Fluke Networks has released an enhanced suite of LAN validation tests as part of its EtherScope Network Assistant. The tests are made up of the expanded Service Performance Tool and the improved Ethernet Performance Tests Suite. These new EtherScope capabilities are designed to maximize network performance and minimize downtime by identifying and correcting problems at the conclusion of a LAN infrastructure project. The expanded Service Performance Tool verifies that key network services are available and responding appropriately. The Service Performance Tool tests the performance of DHCP, DNS, e-mail, FTP, NT file, web and WINS servers. The user can apply custom, service-specific pass/fail limits to each test for quick and easy analysis. The enhanced Ethernet Performance Tests Suite provides the essential RFC2544 tests (throughput, latency, loss, back-to-back), plus advanced tests such as loss rate, jitter and bit errors. Custom test scripts can be created to automate tests for the turn-up of specialized services and to establish test limits for simple pass/fail results analysis.
