Re: [Cerowrt-devel] [Cerowrt-users] Missing packages in CeroWrt repository
I note that the cerowrt-devel list is far more used than cerowrt-users, and you should use that rather than this at this point. Also the #openwrt-devel and #bufferbloat irc channels on irc are good. On Thu, Jul 31, 2014 at 4:34 AM, Paul Tow macskeeb...@gmail.com wrote: I installed CeroWrt two days ago and have noticed that some packages are missing from its repository. Specifically, nginx, rtorrent, tmux, and screen are in the official OpenWrt trunk repository for ar71xx ( http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/ ), but not in the CeroWrt repository. Why is this? It takes 10+ hours to build all of openwrt serially and about 3 in parallel. It takes 27 minutes to build cerowrt with it's more limited package set - and I often have to burn time I don't have to fix some obscure package or another. Given our limited resources and time, what I'd done was pick a good package representative of a need - and just do that, rather than have to support and build the entire smorgasbord. I generally do add packages to the build for which there is a demonstrated need... As for torrent, we basically chose transmission as the most useful, flexible torrent daemon... (think also utorrent is in there, but haven't checked). as for ngnix, at the time we were making package selections (3 years back) lighttpd was smaller and faster. nginx has come a long way since then, and while I've considered switching, lighttpd is still reasonably maintained and more importantly, gave no trouble. Screen run as root has some security issues, and in my own case I've mostly switched to using mosh, which has a partial port done for it in cerowrt. I'd rather fix mosh than add screen, but I can see how it's a desirable utility. Not sure what tmux is used for nowadays. Is it possible for me to list multiple repositories in /etc/opkg.conf, and somehow specify their priority? Then I could set it to prefer packages from the CeroWrt repository, but still have access to packages that are only in the official OpenWrt repository. The opkg page on the OpenWrt Wiki ( http://wiki.openwrt.org/doc/techref/opkg?s[]=etcs[]=opkg; s[]=conf#configuration ) doesn't make it clear if this kind of setup is possible. The core problem I forsee is that mixing and matching binary package repositories will ultimately lead to some sort of toolchain mismatch. Speaking of nginx, I've read that it uses less CPU and RAM than lighttpd and is more actively developed, so I'm curious why CeroWrt's developers chose lighttpd instead. Does nginx have a problem or a lack of needed functionality, or was it not considered? http://wiki.dreamhost.com/Web_Server_Performance_Comparison http://www.wikivs.com/wiki/lighttpd_vs_nginx http://wiki.openwrt.org/doc/howto/http.nginx http://nginx.org/en/ CeroWrt is a great project and I appreciate the work its developers do.

Well that is what you typically do, but you can get away with less measurement traffic: in an ideal quiescent network sending two packets back to back should give you the bandwidth (packet size / incoming time difference of both packets), or send two packets of different size (needs synchronized clocks, then difference of packet sizes / difference of transfer times). Apparently common 802.1ah libraries in most routers can do speed tests at layer-2 for ethernet doing exactly this. (Apparently, one vendor's code is in 90% of equipment out there, cause some of this stuff invoves intimate knowledge of PHYs and MII buses, and it's not worth anyone's time to write the code over again vs licensing it...) But this still requires some service on the other side. You could try to use ICMP packets, but these will only allow to measure RTT not one-way delays (if you do this on ADSL you will find the RTT dominated by the typically much slower uplink path). If network equipment would And correct me if I'm wrong, if you naively divide by two, you wind up overestimating the uplink speed. you can't just test that link, you have to connect to something beyond that. So it would be sweet if we could use services that are running on the machines anyway, like ping. That way the “load” of all the leaf nodes of the internet continuously measuring their bandwidth could be handled in a distributed fashion avoiding melt-downs by synchronized measurement streams… sadly, ICMP responses are rate limited, even when they are implemented in the fast path.

It's also not clear if they are targeting common CPE such as cable modems and DSL routers. These too could use a shaking up. So could all the whiz-bang new ipv6 based features.

HI Michael, On Aug 1, 2014, at 06:21 , Michael Richardson m...@sandelman.ca wrote: On symmetric links, particularly PPP ones, one can use the LCP layer to do echo requests to the first layer-3 device. This can be used to measure RTT and through some math, the bandwidth. Sure. On assymetric links, my instinct is that if you can measure the downlink speed through another mechanism, that one might be able to subtract, but I can't think exactly how right now. I'm thinking that one can observe the downlink speed by observing packet arrival times/sizes for awhile --- the calculation might be too low if the sender is congested otherwise, but the average should go up slowly. If you go this rout, I would rather look at the minimum delay between incoming packets as a function of the size of the second packet. At first, this means that subtracting the downlink bandwidth from the uplink bandwidth will, I think, result in too high an uplink speed, which will result in rate limiting to a too high value, which is bad. But given all the uncertainties right now finding the proper shaping bandwidths is an iterative process anyway, but one that is best started with a decent initial guess. My thinking is that with binary search I would want to definitely see decent latency under load after the first reduction... But, if there something wrong with my notion? My other notion is that the LCP packets could be time stamped by the PPP(oE) gateway, and this would solve the asymmetry. If both devices are time synchronized to a close enough delta that would be great. Initial testing with icmp timestamp request makes me doubt the quality of synchronization (at least right now). This would take an IETF action to make standard and a decade to get deployed, but it might be a clearly measureable marketing win for ISPs. But if the “grown ups” can be made to act wouldn’t we rather see nice end-user query-able SNMP information about the current up and downlink rates (and in what protocol level, e.g. 2400Mbps down, 1103Kbps up ATM carrier) (For all I know the DSLAMs/BRASes might already support this) Best Regards Sebastian -- Michael Richardson -on the road- ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel
Re: [Cerowrt-devel] How is DSL sold and bandwidth managed in the UK?
I shall attempt an answer, probably to a slightly different question to the one you are actually asking. Remember, the UK is a member state of the EU. Cable cost too much to install in the 1980s, partially causing the demise of Nynex. Cable is routed underground here, like most services. All cable, which covers most major cities, out as far as here in the suburbs, is run by Virgin Media. No price competition. Lost a lot of video content to BT and Sky. Probably price competitive with Sky satellite TV. Tiered bandwidth offering, comparable to fibre in speed, heavily traffic-shaped. The telecom operator BT has no state involvement. BT is comprised of two parts. One is BT Retail, which has circa 38 per cent of the retail market. The other part is the supposedly separate OpenReach, which owns and maintains infrastructure, and sells services to 3rd parties. AFAIK, BT Wholesale also sells telephony services to third parties on top of OpenReach services. Because of its dominant position, the regulator, OfCom, regulates OpenReach prices for services to third party service providers. It is currently investigating fibre prices, on the basis that these are too high. Not all services come via BT. TalkTalk has the most separated infrastructure. Sky uses OpenReach fibre backhaul. Local Loop Unbundling means that there are eight or so different DSLAMs in each telephone exchange. Sky and TalkTalk in addition have their own non OpenReach voice telephony equipment. There are two tiers of ISP. One is composed of the big players. These are BT Retail, Sky and TalkTalk. BT Retail have 5 brands operating as separate entities, including Plusnet, notable for carrier grade NAT and traffic shaping. None have caps or download limits. These three are focused around content delivery, principally video. The service is cheap, with a plug in gateway provided. Contracts are generally for one year. Customer service is hopeless. You are paid inducements and cashback to change provider. Whilst the ADSL price is cheap, the cost of the phone line is steadily ratcheting up. If the price of a service increases by 10 per cent or more in a year, the retail customer can leave the ISP, whatever the contract says. I am obliged to pay money to a public corporation, the BBC. These are a major online video content provider, and the main competitor to the three main ISPs for content. These ISPs pay fees to Akamai principally to access iPlayer, and complain about it. The others are the smaller players such as EE, and boutique providers like Zen and AAISP. EE, or Everything Everywhere, are T-Mobile and Orange, a combined unit in the UK providing mobile telephony, and internet services over the BT network. BT Wholesale, I think, provide and run their infrastructure. Zen and AAISP provide a good service over lines rented from OpenReach or TalkTalk. They have customer dervice and respond to faults. They cost ten times as much as the big three, because they make their money by charging for bandwidth. There are many others in this category. Some provide ipv6. Retail customers find deals through sites such as this http://www.moneysavingexpert.com/phones/cheap-broadband The fibre infrastrucure has been rolled out by BT. Fujitsu, and Digital Region, a public enterprise, have pulled out or folded. Sky and TalkTalk currently use OpenReach infrastructure for fibre, but are introducing some of their own cabinets as a joint experiment. OpenReach FTTC uses Huawei or ECI MSANs. I have fibre cabinets 200 metres in either direction along the road. CPE for ADSL is customer installed, and is generally a TrendChip/Ralink or BroadCom based device with the usual driver BLOBs, a 2.6 series kernel, and telnet access.

Perhaps I should add that ADSL2plus services are generally not speed-limited, as well as being mostly uncapped. There are exceptions. Free Sky broadband for Sky TV customers is capped at 2GB per month. Primus, a Canadian company reknown for cheap offerings, has a capped option alongside an uncapped one on TalkTalk infrastrucure. OpenReach offers 40/2 40/10 and 80/10 megabits/s as fibre options. Competitors tend not to offer the middle option. FTTH is capped at circa 350/? megabits/s.
