rtcping v0.1.0 (Initial Release)

We are excited to announce the initial release of rtcping, a lightweight and efficient TCP latency measurement tool written in Rust.

Features

  • TCP Latency Measurement: Measures the Round Trip Time (RTT) by establishing TCP connections to a target host and port.
  • Warmup Support: Optimized for accurate measurements by including a configurable warmup period (default 1s) to prime the network path.
  • Flexible Execution Modes:
    • Ping by count (e.g., -n 10).
    • Ping by duration (e.g., -n 60s).
  • Configurable Intervals: Control the frequency of pings with the -i flag (milliseconds).
  • Protocol Forcing: Explicitly force IPv4 or IPv6 connections using -4 or -6.
  • Comprehensive Statistics: Displays real-time connection results and provides a final summary including:
    • Total packets transmitted and received.
    • Packet loss percentage.
    • Minimum, Average, and Maximum RTT.
  • Graceful Interruption: Integrated Ctrl+C handling allows you to stop the pings early while still viewing the collected statistics.

Installation

You can build the tool from source using Cargo:

cargo install --path .
