wet-behind-the-ears whippersnapper seeking advice on building a nationwide network

Wow this turned into a very long post.... On 09/16/2011 01:10 PM, hasserw(a)hushmail.com wrote: > No one replied with any useful information. I guess no one wants > competition on this list?

The fact that you write from a hushmail address is intriguing to me. That may have kept others from answering entirely. Using ones real name/personal e-mail address builds a reputation. It also helps if you've posted other threads in the past. Looking over my post history (both replies and threads i started), one will see a progression of learning and participation. I don't recall seeing any posts from you in the past. As such, it may not have been wise to burst onto the scene and say "please to do my homework for me". Contributing to a few threads, starting a couple of your own (on a more specific subject) and saying "this is what I'm planning to do, here is what I've researched, please tell me if I'm doing it horribly wrong" is a good way to start in any community. I had high hopes for the thread you had started, but am disappointed by the somewhat juvenile response that you sent. I believe you killed off the opportunity for some excellent discussion. So I'm starting another one, in the event people are ignoring the previous thread. Plus my title is cooler! I did learn some things from that thread (such as nsrc.org) Thank you for posting those links and inspiring the title of this thread Bill. In my case, I have knowledge (through consuming way too much *NOG lists and other resources). However all of my experience is in data center/enterprise LAN networking. WAN experience is limited to default BGP route delivery or statically configured links. So I have never built an ISP network before. I want to join the community, and as such am seeking advice before I blindly go off and end up being one of "those" AS. :) Here is what I am doing and how I plan to go about doing it. Feedback most welcome. Please be critical but polite. :) The previous thread mentioned business plan. That's absolutely critical. Competing on delivering the Internet is foolish at this point in the game. I'm giving net access away for free, and making money off of hyper localized advertising). I'm also using existing co location facilities and networks. Looking over my linked in profile will demonstrate my existing expertise on the business and tech side of both online and hyper local advertising, and large scale, distributed server operations. However I'm currently not experienced on the network build out side. I figured the only way to get the level of experience I want, is to build a service provider network. I'm in the process of building out a backbone network across the United States. Starting off small (3 points of presence: 600 West 7th st Los Angeles, 60 hudson NYC , 324 E 11th KC MO). In two cases I'm leveraging existing relationships with strong WAN engineers who will be receiving some equity in my startup, in one I'm a new customer off the street and doing everything myself other then the basic colo services (net drop, power, cooling, security, smart hands). This backbone network will be used to terminate regional wireless networks. The wireless networks are being funded by the communities that the network serves through direct donations and by hyper localized advertising sales. So here we go with technical nuts/bolts of the plan (as bill so eloquently put it): "I am going to presume OSS and fully depricated kit to keep your costs down and to boost your learning skills." Something like that. 1) Obtain ASN from ARIN (using LOA from existing upstream relationships). 2) Obtain ipv6 space from ARIN (inquired about getting space and ran into some issues. need to speak with my co founder and get details. evidently getting brand new v6 space for a brand new network is fairly difficult. for now may just announce a /48 from he.net. ) Yes I did come up with a sub netting plan for the entire United States out of a single /48. It's quite ingenious really. More details on request if anyone wants them. 3) Announce prefixes from initial point of presence locations for availability / traffic engineering reasons. Using a mix of Quagga on Linux virtual machiens, pfSense on dell servers and Cisco gear. So more or less the steps that Bill mentioned in his response. It was somewhat tongue in cheek, but also quite accurate. I'm bootstrapping with personal funds / gear at the moment. However I believe it can be "done right". I also have a fair amount of gear I've been obtaining over the past few years with the specific intent of building an ISP. The business plan has evolved over time. It's now at a rather mature point, and it's time to get my hands dirty. Whew. Sorry for the long post. Hopefully folks will read it. :)

Internet Governance Fight Looms
by Skeeve Stevens 26 Sep '11

26 Sep '11

Hey all, A pretty important meeting is happening at the IGF (Internet Governance Forum) at the moment with a fight about how the internet itself is managed. The article below gives a good overview of the situation. http://news.dot-nxt.com/2011/09/22/internet-governance-fight-looms The worrying thing is the size and power of some of the countries who want to do things differently than our present multi-stakeholder approach. As the writer quotes "Nothing less than the fate of the future evolution of the Internet is at stake". It sounds dramatic, but if certain powers get their way, it could be close to the truth. There are numerous people from our community going to be attending the event in Africa and no doubt will report back to us with what is happening. …Skeeve -- Skeeve Stevens, CEO - eintellego Pty Ltd skeeve(a)eintellego.net<mailto:skeeve@eintellego.net> ; www.eintellego.net Phone: 1300 753 383 ; Fax: (+612) 8572 9954 Cell +61 (0)414 753 383 ; skype://skeeve facebook.com/eintellego twitter.com/networkceoau ; www.linkedin.com/in/skeeve PO Box 7726, Baulkham Hills, NSW 1755 Australia -- eintellego - The Experts Who The Experts Call Juniper - HP Networking - Cisco - Brocade

OSPF Visualizer?
by Lorell Hathcock 26 Sep '11

26 Sep '11

All: I am a small Wireless ISP in need of an OSPF visualizer that does not cost an arm and a leg. I would like one that can listen to LSA's in each area and build a map of the network. I anticipate that I could trouble OSPF issues with such a system. Any open source projects? Thanks in advance, Lorell Hathcock

--- rps(a)maine.edu wrote: From: Ray Soucy <rps(a)maine.edu> We service most of the state's public schools and libraries (about 1000). Historically the CPE of choice was a small Cisco ISR (1600, 1700, 1800, and 1900 most recently). As bandwidth levels went up, and Ethernet-based transport services became available, we started looking and leveraging FOSS on commodity hardware to lower costs and move services to the edge. Right now we have about 100 of the bigger school districts being services by a Linux-based appliance running XORP for its routing engine (we would have tried Quagga, but they don't support multicast routing yet, nor does Vyatta). It's been a learning experience. Most of the problems we ran into have been resolved by tuning the kernel parameters to act more like a router than a desktop or server. XORP itself has had a rocky ride since we started, so the stability of the project has also been a concern. Thankfully it is seeing somewhat active development again. I will note that XORP is very touchy about how it's configured; if you have well tested configuration templates it's fine, but it's very easy to get it into a crashing state based on something as little the order of configuration directives. For the most part once it's running it's stable. -------------------------------------------------------------------- After roll-out and after a time in steady-state operation did you do an analysis of human and hardware/software costs (as well as service to end sites, such as outages that might not have happened with normal routers and LAN switches) to see if you actually saved money? scott

Re: flow generating tool

Iperf(linux) and jperf(windows) does generate traffic flows. You simply set up sender/receiver and it'll generate traffic load. It can generate 10gig line rate unicast flows but multicast replication is limited because it is software based. Iperf/jperf however, is not as flexible or anywhere as feature rich and powerful as some of the other hardware solutions as mentioned earlier - ex: ixia, spirent etc. -Jia ------Original Message------ From: Erik Bais To: 'Naiden Dimitrov' To: 'George Jones' Cc: nanog(a)nanog.org Subject: RE: flow generating tool Sent: Sep 26, 2011 9:03 AM Perhaps not a tool as in software, but clearly something that you might want to have a look at : Ixia and Spirent devices ... Those are mostly used for applications like generating different kind of traffic. Erik Bais
