What is protocol testing?

Protocol testing is the process of verifying and validating communication protocols in networking systems to ensure they function correctly and comply with standards. It involves checking the data transfer, error handling, and security features between devices that use protocols like TCP/IP, HTTP, or FTP. Protocol testers use specialized tools and scripts to simulate network traffic and analyze how protocols behave under various conditions. This ensures reliable, secure, and efficient network communication, which is crucial for seamless data exchange in modern IT infrastructures.
