No, I don’t think so. AQM is widely deployed to tens of millions of homes in the US – I don’t think the FCC’s intent is to ban such an obviously beneficial improvement in the internet. Rather, they are focused on the notion of creating paid-for “fast lanes” – such as where destination X pays ISP A to prioritize their internet content over other internet content, etc. > Does it prohibit things that some Ethernet NIC "offloads" do (but which could > be done by a provider) such as TCP data aggregation (i.e. the merging of lots > of small TCP segments into one big one)?

No. The use of ECN as a congestion signal is specified in IETF RFCs, is already deployed, is an improvement on waiting for packet drops, and ECN deployment is growing and is to the benefit of internet users & traffic. > Might it preclude a provider "helpfully" dropping stale video packets that > would arrive at a users video rendering codec too late to be useful? Maybe – this will fall into whether that is considered reasonable network management (and for example, why in must be done at the network layer rather than by the user’s client). > Or might this impact larger path issues, such as routing choices, either > dynamic or based on contractual relationships - such as conversational voice > over terrestrial or low-earth-orbit paths while background file transfers are > sent via fat, but large latency paths such as geo-synch satellite? Maybe – could be a reasonable network management decision & it may take a complaint if some party felt disadvantaged - to define what is judged reasonable here. > If an ISP found a means of blocking spam from being delivered, would that > violate the rules?

Could be an issue – we’ll have to see what complaints arise. But likely also falls under the reasonable network management clause, especially if the traffic is not lawful and/or is malicious/abuse. In the past this has been challenging with shared/virtual infrastructure. JL
