For a cable built-out to be 'profitable', you have to get some particular percentage of the 'covered' households to sign up for service. To support multiple providers the total 'penertration' in that area has to be at least: #providers * break-even_subscriber_percentage I have no idea what the current break-even percentage is, but (picking numbers out of thin air for the sake of argument) if it is, say 30% of the households within the service area, then there are simply "not enough customers to go around", even at complete market saturation (where 100% of the households have cable service) to support _four_ "profitable" cable providers. "Overbuild" is practical *ONLY* where: (a) the population density is high, lowering 'per customer' costs, and (b) service 'penetration' is high enough that the active subscriber base (as distinct from 'potential' subscribers) sufficient to support the 'overhead' of two complete, parallel, physical plants. This tends to be 'self-limiting', to up-scale, high-density housing, neighborhoods. The 'raw economics' of the situation may well be distorted by local government 'intrference' -- e.g., requiring a provider serve _all_ households within arbitrary boundaries, rather than just 'low hanging fruit' areas.

Throttle traffic for a single local IP on a Linux router?
by johnc＠hush.ai 24 Dec '10

24 Dec '10

Hi, I know this might not be 100% on-topic and might be better suited for a Linux-distro mailinglist, but I hope to get more diverse methods from you networking experts. Basically, I have a small residential connection, 5 Mbit down, 0.5 Mbit up. A user on my local network, who we will call 192.168.1.105, is using too much bandwidth. I have tried social engineering to get him to stop, he claims to, but iftop says otherwise. My network is setup like this: Cable modem goes to eth0 on router running Ubuntu server, eth1 on the Ubuntu box goes to a wrt54gl (behaving purely as a bridge), and all clients are connected wirelessly. The Ubuntu box handles everything. So I have tried this script, and it does not work -- download speed gets limited just fine, but upload remains unlimited for some reason: TC=/sbin/tc OUTIF=eth0 # Interface for WAN (internet) INIF=eth1 # Interface for LAN (internal network) DNLD=0.5mbit # DOWNLOAD Limit UPLD=0.1mbit # UPLOAD Limit IP=192.168.1.105 U32="$TC filter add dev $IF protocol ip parent 1:0 prio 1 u32" $TC qdisc del dev $INIF root $TC qdisc del dev $OUTIF root $TC qdisc add dev $INIF root handle 1: htb default 30 $TC qdisc add dev $OUTIF root handle 1: htb default 30 $TC class add dev $INIF parent 1: classid 1:1 htb rate $DNLD ceil $DNLD $TC class add dev $OUTIF parent 1: classid 1:1 htb rate $UPLD ceil $UPLD $TC filter add dev $INIF parent 1:0 ip pref 1 u32 match ip src $IP/32 0xFFFFFFFF flowid 1:1 $TC filter add dev $OUTIF parent 1:0 ip pref 1 u32 match ip dst $IP/32 0xFFFFFFFF flowid 1:1 Anyone see any problems in my setup, this script, or have any idea how I can limit the speeds of Mr. 192.168.1.105 without social engineering? Thank you for your time.

Try a Linksys RV016, it has some decent traffic shaping tools for larger home and small business networks.

Re: Wake on LAN in the enterprise
by Owen DeLong 23 Dec '10

WOL is unfortunately terribly deficient in that the spec. never envisioned the possibility of a need for wake on WAN. Bottom line, it's a non-routeable layer 2 protocol. Your choices boil down to the helper address nightmare you describe or proxy servers on every subnet.

Sprint data network contact?
by Stephen Lau 23 Dec '10

23 Dec '10

I'm trying to find a contact for someone who might know something about the proxies running on Sprint's data network. Basically our Android app uses a local http server to serve content to the Android media player, i.e. listening via 127.0.0.1. Unfortunately, a system update that Sprint pushed last week seems to enforce a Sprint proxy (pd.vog.sprintpcs.com:8085) on all HTTP & RTSP traffic... including traffic to 127.0.0.1, which as you can imagine, predictably fails. The EVO is our most popular Android device amongst our subscribers, and we're rapidly losing subscribers because of this problem. This breaks streaming for many Android apps that have to use a local content server (for a variety of reasons, some for playing encrypted content like ourselves, others who need to maintain backwards compatibility with <2.2 Android which lacked RTSP streaming). I'm running into brick walls so far and hoping that someone in NANOG might know a responsible network engineer at Sprint who could help resolve the issue quickly? cheers, steve -- stephen lau | steve(a)grommit.com | http://whacked.net | @stevel

TCP congestion control and large router buffers
by Vasil Kolev 23 Dec '10

23 Dec '10

https://gettys.wordpress.com/2010/12/06/whose-house-is-of-glasse-must-not-t… I wonder why this hasn't made the rounds here. From what I see, a change in this part (e.g. lower buffers in customer routers, or a change (yet another) to the congestion control algorithms) would do miracles for end-user perceived performance and should help in some way with the net neutrality dispute. I also understand that a lot of the people here operate routers which are a bit far from the end-users and don't have a lot to do with this issue, but the rest should have something to do with choosing/configuring these end-user devices, so this should be relevant. -- Regards, Vasil Kolev
