Sep 09, 2005 · Introduction You can use the Test TCP utility (TTCP) to measure TCP throughput through an IP path. In order to use it, start the receiver on one side of the path, then start the transmitter on the other side. The transmitting side sends a specified number of TCP packets to the receiving side. The definitions for the terminology used in the speed test can be found below. Download Speed: The speed of the connection when downloading from the Internet to your computer. Upload Speed: The speed of the connection when uploading data from your computer to another computer somewhere on the Internet. Test your Internet connection bandwidth to locations around the world with this interactive broadband speed test from Ookla The service competence speed of your TEC connection only affects item three in the list above; but your online encounter hinges on the performance of all of those factors. For example, a user with a defectively performing computer, but who is receiving our highest service capability speed for their service type, could actually have a "sluggish An internet speed test will show you the results of the fastest upload and download burst rates during your internet speed test from your location to the location of the test server you choose. TCP/IP degrades over distance so choose the server closest to you when performing the internet speed test.
Use representative streams to test out how link layer compression affects your achievable bandwidth (-F option). A server accepts a single client simultaneously (iPerf3) multiple clients simultaneously (iPerf2) New: Ignore TCP slowstart (-O option). New: Set target bandwidth for UDP and (new) TCP (-b option).
Download Speed: Capacity speed performs a UDP speed test which eliminates the inherent overhead of TCP window management to accurately assess the maximum capacity of a LAN/WAN connection. The download speed is the maximum data throughput from the server to the client that a connection can support. There are two types of Internet Protocol (IP) traffic. They are TCP or Transmission Control Protocol and UDP or User Datagram Protocol. TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol. Multiple messages are sent as packets in chunks using UDP.
The Speedtest operates mainly over TCP testing with a HTTP fallback for maximum compatibility. Speedtest measures ping (latency), download speed and upload speed. TCP Test Components Latency/Jitter. This test is performed by measuring the time it takes for the server to reply to a request from the your client.

TCP/IP degrades over distance so choose the server closest to you when performing the internet speed test. Find out your internet download and upload speed in mbps per second with our internet speed test! Get lightning fast internet speeds starting at 100 mbps with Spectrum. The test is then run between the two end-end JDSU T-BERD/MTS-6000 or a 6000A and an iperf server. After completion, the user is presented with an easy-to-understand test report that clearly highlights the window size versus throughput performance, as Figure 5 shows. For this test, the link speed was 1 GigE and the RTD was 1 ms.
