On DSL, the sync rates in each direction should usually be readable from the modem; they are typically reported on the router's status page. The advertised rate is less reliable, to say the least. On wireless links, all bets are off - even with stationary endpoints, link capacity varies wildly over time. This needs to be solved in the radio-modems. If it's wifi, however, a link-rate-independent solution now exists for certain hardware, and there's nothing theoretically stopping something similar being put into future HardMAC implementations. If we get the choice of hardware, naturally we choose wisely. - Jonathan Morton ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel

Re: [Cerowrt-devel] Invisibility of bufferbloat and its remedies
I have been one of the most prominent advocates of network neutrality. I'm constantly informing my friends and the press about "buffering" not being related to neutrality at all. I think that's the best we can do. Packet neutrality is actually a key part of the Internet's design, pushing control mechanisms to the edge, with a minimum of "intelligence" in the routers/switches/gateways. In particular, "content-based" and "endpoint-address-based" targeted throttling was never how the Internet Protocol layer was supposed to work. That's a fundamental result of the "end-to-end argument" applied to congestion management. I've spent a lot of time on that issue technically. The original discussions going back before Van Jacobson's early work, up to RED and ECN, all are based on providing congestion signalling sufficient to cause endpoints competing for resources to adapt their behavior cooperatively in real time, while maintaining minimal latency under load. Latency under load is the crucial metric across the entire IP layer, endpoints and routers. It's clear that minimizing latency under load has to be achieved by avoiding buffering insite the network, moving it to the source (and destination). I've given this lecture to policy people a lot. In fact, deliberate creation of "bloat" is a technical strategy that has been used in the past to destroy VoIP and other real-time communicaitons. Microsoft was caught doing it decades ago, as were some other conflicted communicaitons providers. They could selectively delay small packets using DPI, while letting FTPs get full speed. That's one of the reasons we coined the idea of Network Neutrality. But radical right wingers of the sort that blossom in the paranoid world of the dark net started arguing that the routers should have political freedom to do whatever they damn well pleased with packets, because routers are people just like corporations, and a "free market" is the solution to everything. Well, technically, the Internet doesn't work if their is not some mechanism for eliminiating lag under load by eliminating queueing delay in bottleneck nodes. That's ultimately what Network Neutrality is about. There's a lot of other crap being pushed by folks who pile on to the Network Neutrality discussion. People want to "fix prices" for example, arguing that profits are bad. Those guys are not the problem. The problem is that the vertically integrated monopolists want to claim that the Internet should be subject to Deep Packet Inspection at every router, designed to charge rents based on content of the packets and who is the original sender or destination of the packet - that is, charging Netflix or NBC Universal packets nothing, and charging IPFS packets 100x as much. So, no, the Network Neutrality people are NOT the problem with Bufferbloat. Comcast, on the other hand, has been slow-rolling DOCSIS 3.0, because their customers on DOCSIS 2.0 are just ordering faster service tiers to overcome the Bufferbloat in their DOCSIS 2 CMTS's. -Original Message- From: "Dave Taht" Sent: Monday, June 18, 2018 3:07pm To: "dpr...@deepplum.com" Cc: cerowrt-devel@lists.bufferbloat.net, "bloat" Subject: Re: Invisibility of bufferbloat and its remedies On Mon, Jun 18, 2018 at 9:26 AM, dpr...@deepplum.com wrote: > https://www.cordcuttersnews.com/3-easy-tips-to-fix-constant-buffering/ > > It's distressing how little the tech press understands the real problem.

A thing that I tried to get ISOC's "deploy360" to do was to create a wall of shame on bufferbloat five or eight years ago. It was before the AQM WG did any work, I think. I wanted ISOC to collect the data, because I wanted it visible at the CTO level. At the very very least, I wanted a series of curated links to statements from various equipment vendors about the problem. I.e. www.example.com/bufferbloat.html for example in {cisco,juniper,huawei,calix,...} I asked many of my IETF contacts at these places if they knew who at their company was dealing with it. I also asked salespeople that I dealt with, hoping to put pressure the other way. I got nowhere. I wanted, at the very least, to get them to acknowledge that there was a problem, even if they didn't have an estimate on a solution, at least I could point the salesperson at the page on their site, and say, "I'll buy when you get me a delivery date". A major client of mine lost three large (VoIP) customers because of hidden bufferbloat in Bell Canada's LAN extension service... which "never lost any packets", the sales people explained. It was at a time when we weren't quite using the term bufferbloat, and we didn't quite know how to measure it in convincing ways.

My principle observation is that with the changes in traffic patterns in the last decade, and the predominance of application-rate limited streaming, that most folk are merely forced into a bandwidth tier that is less rarely annoying. This does not of course solve the corporate gateway problems very well, nor does it truly kill it dead, but until that day when "the right stuff" is readily available, and more informed demand exists.

I have essentially abandoned the IETF as the inmates are running the asylum, and trying to continue to make our points there was seemingly fruitless - and out of my budget. I'd rather stay home and get better code out the door. Or come up with some other set of orgs to annoy into paying attention.
