Re: What software do you use to manage your connection speeds? said by jcremin:Assuming you are using a PPPoE server at the core, I don't quite understand how this is possible. Yes, lots of small packets can cause problems no matter what, but if you use PPPoE, the CPE basically has a VPN to your core router. Clients can only push or pull traffic at the speed of their connection and they can't get an unlimited amount of bandwidth between other customers because it has to flow through the core. The one downside is that if you have two customers on the same tower transferring a file between them, the traffic has to flow over the backhaul to the to the core, then back over the backhaul to the tower again. I use static routing.. so it is indeed possible, however, you are correct with the PPPoE |

said by j2sw:I think it is a given in which every POP should have a router. We try to let the AP do AP stuff and let a router at the bottom do the ques and other such functions. I would say that is a lot better than relying solely on the CPE to do the limiting/queues, however I think having extra routers at each tower adds extra complexity and more points of failure. I have chosen in my network to keep everything as simple as possible. A tower does two things... 1) broadcasts to the client, and 2) backhauls to other towers or the central "hub".
I have my main site which has my PPPoE server, and a second site where my backup bandwidth is that has a failover server. |

said by Inssomniak:I and many other users control the speed of hundreds of users no problem with mediocre hardware. I would agree with this statement 100%. My main PPPoE server is a simple Mikrotik RB450G. Handles around 200 simultaneous users and hovers just over 10% CPU usage. I use the Userman package on the router as my radius server, so once I throw in a power supply and enclosure, I have a PPPoE server which is capable of hundreds of users for just over $100 and only consumes around 5 watts... My battery backup systems love me  |

On some of the larger, more busy networks we actually have two routers. One is a "backhaul" router with nothing but backhauls. This can be a high end Mirkotik or a Cisco Layer3 switch. Then we have a an "Ap router" which does queing, PPPoE stuff, and the like.
