X-BeenThere: bloat@lists.bufferbloat.net X-Mailman-Version: 2.1.20 Precedence: list List-Id: General list for discussing Bufferbloat List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 25 Aug 2018 16:57:48 -0000 I'm always casting about for some simple metric, some simple phrase, that we can use to describe what we're about. Lately - without formally defining it mathematically as yet - I've been talking about "badwidth" - what you get from your typical ISP - and "goodwidth", what debloating does - which originally sprang from me typo-ing "bandwidth". More recently I tried combatting the perception that packet drops/marks are "bad", by renaming them to "debloats/day". Codel kicks in rarely, but I'm pretty sure every time it does it saves on a bit of emotional upset and jitter for the user. For example I get about 3000 drops/ecn marks a day one inbound 100mbit/20mbit campus link (about 12,000 on the wifi links), and outbound a mere ~100 or so. But: Every one of those comforts me 'cause I feel like I'm saving a ~500ms latency excursion for all the users of this (640ms badwidth down/280ms up) comcast link. I am kind of curious as to y'all's regular "debloats/day"? --=20 Dave T=C3=A4ht CEO, TekLibre, LLC http://www.teklibre.com Tel: 1-669-226-2619
