| May 8, 2017 at 16:11 | comment | added | nijave | Bandwidth control--to me--seems like a broad term to describe any technologies to reduce and restrict bandwidth such as throttling/shaping, caching, whitelisting/blacklisting. Traffic shaping implies certain types of traffic are restricted. QoS is sort of the opposite--certain types of traffic are prioritized in the case of congestion. Maybe it would be good to see how they're being used? | |
| Jun 28, 2011 at 11:00 | comment | added | Caleb | @Mark: My question about usage wasn't about real-world application of the technology, it was about current usage of the existing tags on ServerFault. Is this distinction useful in sorting the current questions and are the proper tags actually applied to questions? Or is everything just tagged with whatever comes to the OP's mind (including all three because they don't know the difference)? | |
| Jun 28, 2011 at 2:17 | comment | added | Chris S | QoS is policy as applied to traffic (queue priority, CBR, CIR, DBR, etc). Traffic-Shaping is applying bandwidth policy to particular types of traffic. While they're very closely related, there's a different. In-App QoS or Traffic-Shaping is part of the paricular app and shouldn't be tagged as the others (unless the question related to their interaction of course). | |

@Gilles, we shouldn't let program/application options/parameters become tags, unless there is some really overwhelming reason to do so, so the apparent similarity of --bwlimit and bandwidth-control is quite irrelevant.

| Jun 27, 2011 at 23:28 | comment | added | sysadmin1138 Mod | @Gilles Since Rsync bwlimit does its limiting in the app itself rather than via QOS, I'd call that use-case traffic-shaping. The entity doing the traffic management is an application well above the TCP layer. QOS is in the TCP/IP protocol stack. | |

Do rsync --bwlimit and friends fall under traffic-shaping? They're surely bandwidth-control.

| Jun 27, 2011 at 22:09 | comment | added | Mark Henderson Mod | @Caleb - qos and traffic shaping are both in theory and in practice quite different things, and they require different solutions. QoS is administered quite differently to traffic shaping. QoS is often a client-side protocol, and traffic shaping is a server- (or gateway-) thing. | |
| Jun 27, 2011 at 22:06 | comment | added | Caleb | I see the conceptual difference you mention, but is that born out in usage? Time for some cleanup or do the available tags need fixing first? | |
