• Speed: This test measures your actual download and upload speeds, quality of data, and TCP efficiency. It uses TCP/20000 for download testing and TCP/20001 for upload testing.
• Route: This test validates your connection quality, including packet loss, latency, round trip, and ISP peering points. It uses Internet Control Message Protocol (ICMP).
• Capacity: This test measures your potential maximum download and upload speeds. It uses UDP/8090.
