Throttling bandwidth with Go

Throttling bandwidth with Go

Imagine a service that is serving big log files over raw TCP, you decided to implement simple QoS for an existing server.

The goal of the task is to create small Go package that would allow for throttling bandwidth for TCP connections.

Requirements:

  • keep it simple
  • think of it as open-source software that builds upon existing solutions

video and latency

  • Vehicle moving at the speed of 130 km/h moves 3cm/ms Typical reaction time of a driver is 500ms-1s. We want to target 1-5% of the driver reaction time (regulaton will say it's word for sure if the remote driving gets popular). This is 5-50ms round trip. For slower moving vehicles like forklifts the network latency can in the 100-500ms range? Under 5ms roundtrip latency is not realistic in the modern generally available IP networks (proprietary microwave relay here?).
  • We need to deliver high quality video only for the area where the driver has his eyes on.
  • We shall ensure under 5ms latency between recognition of a saccade and displaying a high resolution image in the right place.
  • The car can record 360 degrees view in high resolution, but send only low resolution stream for all or most areas.
  • We want to minimize the network latency and impact of the network congestion. One of the ways to do this is to require 100% visibility for the microwave transmitters.

Have happy days and cozy evenings,
Onerous tasks being easy dealings,
Travelling the world enjoyable and fun,
Wonders of the nature being a sweet bun.
Ignorance of ever young and merry
Never you neglect, but always carry.
Do not forget your serfs, my charming fairy.

Моих желаний томных несосчесть,
