By implementing rate limits, users can optimize application performance, prevent excessive bandwidth consumption and ensure stable and reliable connections. This guide will introduce step-by-step how to configure the rate limit settings of Yi2, covering a variety of platforms and scenarios to meet the different needs of users.

Yi2 Rate Limit

Introduction

Yi2 is a command line tool for rate-limiting network traffic through a time-based sliding window. It allows users to limit inbound or outbound traffic based on bit rate or messages per second (MPS).

Implement rate limiting

To implement rate limiting using Yi2, follow these steps:

1. Install Yi2: Use a package manager (such as npm or yum) to install Yi2.
2. Set rate limit rules: Create a rule to specify rate limits. For example, the following rules limit outbound traffic to 100 kilobits per second:

 yi2 -o -r 100kb/s

3. Startup Rate Limit: Run the command to start the rate limit:

 yi2 -s

Advanced Options

Yi2 provides additional options to configure rate limiting:

• Time-based sliding window: Rate limiting is based on a time window that moves over a certain period of time. Use the -w option to specify the window size in seconds.
• Burst rate: In some cases, the allowed traffic temporarily exceeds the specified rate limit. Use the -b option to specify the burst rate in bit rate or MPS.
• Inbound/outbound traffic: Use the -i and -o options to specify rate limits for inbound or outbound traffic, respectively.

Example

The following example creates an inbound rate limit that allows 1000 messages per second and has an outbreak rate of 2000 messages:

 yi2 -i -r 1kmsg/s -b 2kmsg

Uninstall rate limit

To uninstall Yi2 rate limit, run the following command:

 yi2 -r
