Re: what will all you who work for private isp's be doing in a few years?

Not pointing any fingers but many of you think these small ISP's are just going to die off instead of adapt. Wireless is becoming a better and more reliable technology that in the future will be able to provide faster service then FTTH. I know of atleast one small ISP in Michigan that went from dial-up to deploying wireless. With WiMAX coming out I think you will see a number of smaller ISPs switching to it as a service. It is also much cheaper to deploy a wireless network. Me personally, I think wireless is the future for residential internet/tv/phone.

Vonage To Make 911 An 'Opt-Out' Option
by Fergie (Paul Ferguson) 12 May '05

12 May '05

Just as an FYI: In an interesting turn of events (e.g. multiple states suing Vongae, multiple RBOC's now offering to make their E911 infrastructure available to VoIP providers in the face of ineveitable FCC madates to do so, etc.), Vonage is saying that they will make their E911 "service" and "opt-out" option, instead of an "opt-in" option. http://www.advancedippipeline.com/163101312 - ferg -- "Fergie", a.k.a.

Malicious DNS request?
by Joe Shen 12 May '05

12 May '05

Hi, In past days I noticed the nxdomain statistics in named.stats keeps increasing.( I run it every 5 min) By tcpdump, it's found a remote computer keep asking address for record like 999d38e693b9e6293b450.0existence.com, 60d38e693b9e6293b450.0be6c1xfa.net. is that a virus affacted computer? How could such request be filtered or minimize its affaction on DNS server? regards Joe __________________________________________________ Do You Yahoo!?

Re: competitive network overbuilds
by Frank Coluccio 12 May '05

David Barak noted: >>It should be noted that the same statement applies to DSL, FTTH, or RFC-1419 service as well: anyone who wants to CAN do an overbuild, and in fact that would probably be the best for customers in the long-run. A very timely comment, and IMO you are correct. Especially with respect to "that would probably be the best for customers in the long-run." ;) But there obviously are limits. I have at times been involved with, and seen the work of others who have attempted to come up with a number that defines just how many horizontal service providers - at the various layers of the stack -- with glass-wireless at 1, gigabit Ethernet at 2, and Internet at 3 -- a given service territory could support. Analysis must take into account the needs of the citizens being served; the SPs' viability and financial sustainability; and the sheer logistics of the situation, given the limitations of time, space and the need for elegant hand offs to customers through the use of a minimal set of channel interfaces and speeds. Given an area where poles and underground conduits are already occupied with at least two wireline heavyweights, namely the duopoly players who are happily dancing to the tune of "inter-modal" competition that was given a blessing by the FCC, plus the electric company on the ground, and three-to-four wireless providers who already are renting space on existing tower structures for WiMAX, how may more trenches, poles and towers can the support structures and rights of way in many populated areas support? Consider a simple example, albeit, one that is more easily stated than accomplished, granted: A fiber condominium builder receives permission and a franchise to overbuild glass onto an entire town's existing copper footprint, resulting in a shared Layer 1 resource that allows upper layer Service Providers to rent fiber from them in the forms of feeder, distribution and drop cables right up to each end point.

Aside from the Switch & Data in Southfield and the nearby Level 3 location, has anyone encountered good locations for private peering in the metro Detroit area?

re: what will all you who work for private isp's be doing in a few years?
by Fred Heutte 12 May '05

(1) There will be a market for independent ISPs as long CLECs continue to let their customers enjoy poor service and unnecessary restrictions. Bandwidth is a "commodity" and scales appropriately; service is "service" and does not scale without a great deal of management commitment, resources, money, attention and abandonment of the cut-costs/low-bid mentality. (2) This discussion is more appropriate to the ISP-CLEC list. Wish I could be with you all in Seattle next week but work is piling up so . . . back to work/lurk mode . . . phred ------ mail forwarded, original message follows ------ To: nanog(a)nanog.org From: Mbazan(a)onelegal.com <Matt Bazan> Subject: FW: what will all you who work for private isp's be doing in a few years?

You forgot to mention Verizon's Fios (fiber to the house) which will definitely put smaller dsl resellers out of business, unless Verizon gives them access to resell that as well. 15Mbs/2Mbs for $49.95 is going to make even the cable operators scramble to increase bandwidth to maintain customers. -----Original Message----- From: Matt Bazan [mailto:Mbazan@onelegal.com] Sent: Wednesday, May 11, 2005 2:09 PM To: nanog(a)nanog.org Subject: what will all you who work for private isp's be doing in a few years? why in the world would anyone want to purchase dsl from a private reseller when i can get 4mb down 384 up from comcast for $25? think you dsl resellers out there are doomed. in fact, just a matter of time before most of you isps are down the toilet. im reminded of the mom and pop grocery store phenomenon that has now been replaced by the kohls, a&p, whole foods etc. of course there will always be niche markets but this is less applicable for a pure commodity like bandwidth. yeah, i suppose you'll say something about value added services and such and you may have a point but i doubt that will keep the ship afloat for long.
