The TCP test uses the standard TCP protocol with acknowledgments and follows the TCP algorithm on how many packets to send according to latency, dropped packets, and other features in the TCP algorithm. See TCP – Test Equipment Requirements for a list of test equipment, including specifications, required to complete the TCP. The higher layer, Transmission Control Protocol (TCP), manages the assembling of a message or file into smaller packets that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. This is more common than you might think because a lot of people use VPN for media streaming and torrenting, both of which typically use TCP. These tests can measure maximum TCP bandwidth, with various tuning options available, or, by doing a UDP test, the delay, jitter, and datagram loss of a network. PsPing Network Latency Test The major drawback of this web based Azure speed test tool is that this tool does not measure latency with ICMP ping or TCP ping, due to browser limitation. 43 mbps Linux host.
