DreamHost Web100 based Network Diagnostic Tool (NDT)
Located at Los Angeles - CA;
1000 Mbps (Gigabit Ethernet) network connection
This java applet was developed to test the reliablity and operational
status of your desktop computer and network connection. It does this by sending data between your
computer and this remote NDT server. These tests will determine:
- The slowest link in the end-to-end path (Dial-up modem to 10 Gbps Ethernet/OC-192)
- The Ethernet duplex setting (full or half);
- If congestion is limiting end-to-end throughput.
It can also identify 2 serious error conditions:
- Duplex Mismatch
- Excessive packet loss due to faulty cables.
Systems behind firewalls must permit TCP ports 3001, 3002, and 3003.
A test takes about 20 seconds. Click on "start" to begin.
