    Defines the sending rate, in packets per second.

-p port
    Specifies the UDP port to use.

-i interval
    Sets the reporting interval, in seconds.

    Timestamp packets and report delay measurements

eutp is a command-line utility designed for performing various UDP network tests. It's an enhanced version of simpler UDP testing tools, providing more control over packet generation, timing, and reporting. eutp can be used to measure network bandwidth, packet loss, latency, and jitter. It supports sending and receiving UDP packets of configurable sizes and rates, allowing users to simulate different network conditions. The tool is valuable for network administrators, developers, and researchers who need to analyze UDP network performance. It's useful for troubleshooting network issues, verifying network configurations, and evaluating the performance of UDP-based applications. It includes functionalities for timestamping packets which allows you to do latency measurements.
eutp helps users to gain deeper insights into the behaviour of UDP traffic.

eutp requires appropriate network permissions to send and receive UDP packets. Results may be affected by network congestion, firewall rules, and other network conditions. Packet loss and jitter measurements can be sensitive to system load on both the sender and receiver. eutp might require root permissions to bind to certain ports.

To send UDP packets of size 1024 bytes to host example.com on port 5000 at a rate of 100 packets per second for 10 seconds, use:
eutp -s 1024 -r 100 -d 10 example.com -p 5000

To timestamp the packets sent to example.com:
eutp -T example.com

The eutp command has evolved to provide more advanced UDP testing capabilities compared to basic tools like ping using the UDP protocol.
It was developed to give network engineers a dedicated tool to test UDP network performance, with more options for packet size, rate and time interval configuration.
