Dual Queue Networking: How to Prepare Your Network to Support L4S and NQB

[@robertmcmahon921]

I think it might be better terminology to use term "fronthaul" for in premise "transit" networks which are from the OSP demarc (e.g. Cable MODEM) to the per room radio heads. Backhual is too confusing here, at least to me. Then there are three fronthaul choices in priority order, fiber fronthaul, copper fronthaul and wireless fronthaul. Copper & ethernet is going got top out at 10Gb/s. The signal loss of 100Gb/s over copper is in dB per inch, roughly 4 meters for a passive cable. Signal loss over fiber is .5db per kilometer and is independent of modulation and will scale to petabits/sec. So, make sure while you're installing communications fronthaul conduits to consider future fiber pulls too. The per room location doesn't really need a wall outlets as the fiber can be connected to wireless radio in the ceiling. It's sorta analogous to irrigation systems where the physical aspects of the landscape and plants should influence both the sprinkler heads placements and how the PVC is laid and zoned. Placing the radios (and antennas) properly and using a proper fronthaul design will help a lot.

How to handle lots of flows through a queue? Focus on the elephants? kzbin.info/www/bejne/j3q2pp2PmNOVias

Individual flow through a queue can be categorized as a micro-flow (based on ip tuple) which could then individually be monitored for good behaviour (Queue Protection).
