TCP Test

TCP Test

The NQA TCP test measures the time taken to set up a TCP connection between an NQA client and a TCP server through the three-way handshake.

The TCP test process is as follows:

  1. The source (SwitchA) sends a TCP SYN packet to the destination (SwitchB) to set up a TCP connection.

  2. The destination receives the TCP SYN packet and responds with a TCP SYN-ACK packet.

  3. The source receives the SYN-ACK packet and sends an ACK packet to the destination. The connection is now established and the source can calculate the time taken.

Figure 6-7  TCP test scenario

Frequent TCP tests can consume too many resources and affect device performance.

TCP test results and historical records are collected in test instances. You can run commands to view the test results and historical records.
