Medicine Hat, AB | Qos question I am using actiontech firmware on telus for quite sometime now. No issues. So i turned qos off.
I am looking at getting an apple tv or something similar.
If i use netflix or anything i am probably going to want to setup qos.
My question however, is does it reserve that bandwidth when needed, or whenever the network detects the ip address?
I have never used it before so im not sure how it works. My concern is if i leave it (apple tv on 24/7) but am not using apple tv or whatever will it still reserve that bandwidth because its detects that ip on my network. Or will it only use the bandwidth when needed.
Maybe someone could specify, or explain it to me. |

| Great Question! I'm also interested in knowing if the Qos feature in (most) routers is "smart" in that is assigns/caps predetermined bandwidth for devices and services in a non linear fashion. |

I hadn't modified the QoS on my setup and I have no issues running Netflix in HD while the TVs are running or using the internet. Try it first and see if it works before changing QoS. |

The QOS for most consumer level hardware is really only designed for the upstream portion. And realistically, thats the only part you can control. Yes you can do some "TCP ACK" tricks to sort of throttle the downstream portion, but it doesnt really work as well as you think it would. The QOS is mainly for bittorrent or other p2p things, and to leave some room to make HTTP requests for your browsing. In regards to apple tv/netflix, it probably wont make a difference as that is all downstream stuff. |

QoS bits are used in IP networks to prioritize packet traffic, and are generally ignored. Wikipedia offers a decent explanation here: »en.wikipedia.org/wiki/Quality_of_service
The exception to this is IPTV and VOIP services, where a minimum flow of traffic is required. However, as jjthegreat says, this normally does not happen in the CPE (Customer Premises Equipment), but in more sophisticated router equipment. |
