Powerful Linux ISP Router Distribution?
fibrewire writes "I'm building a Wireless ISP using commercial grade, low cost equipment. My main stumbling block is that I cannot find a decent open source ISP class routing distribution. Closest thing to even a decent tool is Ubiquiti's AIRControl — but even it doesn't play well with other network monitoring software. I've used Mikrotik's RouterOS for five years, but it just isn't built for what I need. I don't mind paying licensing fees, but $300K for a Cisco Universal Broadband Router is out of my budget. Has anyone seen any good open-source/cheap hardware/software systems that will scale to several thousand users?"
So AirControl "doesn't play well with other network monitoring software" (which one, and why?), and MikroTik "isn't built for what [you] need" (what's that?) - other than that, you don't give us any idea what you really expect. What are your requirements? Suggestions out of the blue: OpenWRT with quagga/zebra, hostapd, radius, olsrd, b.a.t.m.a.n. etc. etc, or you might want to have a look at Vyatta (no affiliation).
So Cisco makes billions of dollars a year selling some ungodly expensive, ungodly powerful head end router like devices (not even routers in the IP sense) and somehow you suspect a Linux distribution with the same features is going to unpack itself and be everything you want it to be? You need to tell us what the rest of your platform looks like if you expect any answers that go beyond 'any linux distribution can act like a router!'. What subscriber equipment is in use? How much user control do you need (access on/off vs. bandwidth filtering, etc.) Details, details, details.
I'm building a Wireless ISP using commercial grade, low cost equipment.
To me, some words in this sentence seem to be mutually exclusive.
To my humble opinion, a good ISP needs to have good reliable equipement. Sometimes, out of the box routers are better because they don't have moving parts and their firmware could be more stable than a full-blown OS (even if it is Linux).
Disclaimer: Not that I don't like Linux, I use it all the time.
Sorry to be blunt, but you're asking the wrong question.
The proper question is: How do I find someone qualified to do this for me?
The fact that you are asking on slashdot shows that you are not qualified, and what you're going to get back is a bunch of others, who aren't qualified, suggesting all sorts of half assed hacks to do it which will just result in a utterly shitty service overall.
You could get by with this in the late 90s, but when you're going to compete with cell phone companies, cable companies and standard POTS companies, you probably need to have a bit of a clue.

Maybe Vyatta @ http://www.vyatta.org/ does what you want. I really don't have any idea what that is from the actual post, tho. You need some routing for thousands of users, and can't afford a Cisco UBR. I'm not sure exactly if you wanted to use the UBR for DOCSIS type support for some reason (a la cable modem) but the fact it'll be wireless leads me to believe it won't be. I'm assuming you don't need a lot of physical ports, just something to manage your VLANS, some routed subnets, a bit of BGP, etc. Maybe XORP is what you want, tho @ http://www.xorp.org/ so you may want to look there. IHeck, 'm not even sure if you want to take a server with a bunch of PCIe ports and slam multiport switchable fabric cards in there like the ones DSS @ http://www.dssnetworks.com/v3/gigabit_pcie_6468.asp makes, or do something else. Maybe these links will help, and hopefully there'll be a detailed followup so we can aim at the real target :)
Routing and ISP's are huge topics- what are you trying to do?
The main problem with routing isn't bandwidth- anyone can pump enough 1500 or 9000 byte frames per second to fill a gigabit pipe. The problem is when you have lots of small packets. At that point, dedicated routing hardware with a high-speed TCAM becomes really important.
What kind of line cards do you need? ADSL? Ethernet? OC12?
What kind of services do you need to run? BGP? OSPF?
What kind of bandwidth are you going to be pushing?
Start off small. Pick up some used Cisco stuff off Ebay at 1% list. Maybe a 6500 with a couple of SUP2s for your core switch, a couple or four 7200s for the upstreams/customer facing bits. Make lots of money, upgrade to newer stuff as needed.
What's your interface to the net, line cards, bandwidth expectations, etc. I spent 5 years building a fairly heavy duty wISP network on a stupid low budget from my boss. You can obtain used cisco stuff for cheap. For instance, you can get your hands on a 7206vxr with a NPE-G1 for $10k or less nowadays... If you need something with high redundancy do do less intensive switching, you can pick up a 6509 with a pair of SUP2-MFSC2 cards for less than $2k. As far as support contracts go, I can't imagine that you need the latest and greatest IOS, let alone a support contract that costs more than the replacement of a piece of hardware. On a side note... why are you asking about the uBR series? Are you not running an ethernet network? Last I checked, there's no such thing as "low cost commercial grade." Depending on where you are, unlicensed stuff may not cut it, dealing with interference etc. And licensed hardware is certainly not cheap. With wireless, as well as so many other areas, you get what you pay for.
Macs, Linux, Windows... who cares, they all suck at something.

It's Linux on low cost wireless routers.
Yeah, that's just what I'd want my ISP to run as a core router.
Seriously, learn to love FreeBSD.
I am assuming that you will be doing a tree style network with a central location providing you bandwidth on a fiber link or T1/T3 etc.
Get a PAIR(at least, add more as necessary) of nice, quad core Dell Poweredge or HP DL series servers. FreeBSD+CARP them giving you as seamless load balancing/fail over as you can realistically get.
at each hub consider either buying commercial wireless routers or build your own. If you build just keep everything fanless as that is where your equipment will fail you.
Use OSPF on branches while being aware of scaling issues and where OSPF isnt ideal, kick in the BGP and you can link your OSPF clusters together giving an extra level on branch redundancy because traffic can hop to another branch if necessary.
OLSR in mesh cells, OSPF on the cells backhaul router linking these cells and providing multiple route options for redundancy, and BGP between groups of cells and between you and other ISPs etc etc.
You dont need to take the Mesh down to the client, only to the neighborhood AP level. The idea of mesh per client creates too many hopps and clients have too much latency. Ideally, you are no more that a 2-4 hops from the backbone, any more and you are going to be adding too much latency from the hops. When a backhaul link goes down and the OSPF saves your butt by routing traffic through a neighboring cell, you are already going to add latency and you dont need that complicated by 6 hops in the neighborhood and 5 more to the backbone (11 hops over wireless is just too many for broadband).
