Call duration was 81s. Average speed was 80pps. The avg packet size was 200b. The call was "BYE" at 60 seconds, but there was a REGISTER at 76s so I included that as the call teardown marker and in the averaging. I didn't think being liberal would hurt. -M<

Advanced IP Pipeline: "Someday, customers of wireless broadband provider Clearwire Corp. may be able to use Voice over IP services. But right now, Craig McCaw's newest company is giving its customers the silent treatment by apparently blocking outside VoIP providers from its network." http://www.advancedippipeline.com/news/159905772 - ferg -- "Fergie", a.k.a.

Good afternoon, The NANOG list is not an appropriate place for speculative critiques of the business models of individual companies. Furthermore, this thread has gone completely off topic.

Of course those people are going to want some money - and nearly all sales people work on some type of base + commission basis. It's up to you to decide what is less expensive and better for you. Either one is going to cost you something. Sitting around waiting for people to come to you can also be pretty expensive if you have any kind of fixed expenses. Mark Radabaugh Amplex

There's really nothing wrong with what they are doing, although they may not have explained it to you too well. What they do is become an agent, or reseller, for a company and they get a residual on anyone they refer. So if you are a corp IT guy and you have no clue as to who's out there and what the prices are, these kinds of services "can" be useful. Almost everyone will give someone a residual for a referral, but you have to ask. :-) -M<

RE: "Bandwidth Advisors" - www.bandwidthadvisors.com
by Cameron Jones 25 Mar '05

25 Mar '05

I've worked with Aaron from BandwidthAdvisor several times over the past few years. He's a top notch guy, with a great list of providers and clients. He's simply an independent agent, and gets paid for bringing business to your door. In my opinion you can't ask for a lot more than guys out there in the field pushing your products for you, with no guarantee of even a base salary. Aaron has a great international network, and is very well known in the Seattle area.

I don't see anything on their web site that labels them as "brokers". I do see under their FAQ... Q. How does Bandwidth Advisors get paid? A. Bandwidth Advisors receives a small residual payment from the Telcos once the Client begins paying for the service. Nice to see it there. I know a bunch of consultants out there (me being one, Bill Woodcock, etc.) that do not take money from vendors they recommend. How can a client of a consultant really know they have the best deal when the "consultant" will not investigate all of the options out there? For those that don't know... I am now the COO of UnitedLayer. It sounds like, since I am not going to pay the "extortion" fee to Bandwidth Advisors, that their consultants won't know about our pricing and services. Even if I did pay the fee, that means that their clients can't get the best deal as I need to raise my fees to client to cover the "small residual payment" going to "Bandwidth Advisors".

Tier-2 reachability and multihoming
by G Pavan Kumar 25 Mar '05

25 Mar '05

Hi there, I have been working on characterizing the internet hierarchy. I noticed that 27% of the total possible tier-2 provider node pairs are not connected i.e., they dont have any tier-1 node connecting them nor a direct peering link between them. Multihoming can be used as a predominant reason for the reachability of tier-3 nodes which are customers of these nodes, but what about the reachability of tier-2 nodes themselves and its customers which cannot afford to multihoming? How does BGP solve this reachability problem when it gets a request to a prefix unreachable? 1 tier-1 / 2 4 tier-2 / \ / \ 5 6 7 8 tier-3 here, nodes 2 and 4 have no reachability, 1 / | 2 3 4 / \ \/ \ 5 6 7 8 now, node 7 is reachable from 2 and its lower level nodes, but what about node 4 and 8, and as a typical case, suppose nodes 4 and 8 have no multihoming whatsoever, what then? Regards,
