RE: Strange network problem accessing Ebay and versiontracker websites
We don't use PPOE. Our network setup is DSL Modem -->ATM-->BLC (Occam)-->IP--->Router--->Transit provider. Basically we turn on the service and it's always running. We don't require any authentication or do any subscriber management on our users. I will start looking into the MTU issue though.

It sounds like that is a possibility. Are the DSL users being served by PPPoE? Setting the IP MTU on your PPPoE access template, depending on whose gear you're using to provide the servide provider end of your DSL services, to 1492 may help. jms
Strange network problem accessing Ebay and versiontracker websites
All, I know this probably isn't the best forum for this question but I'd like to rule out a network problem before I tell a customer he has a PC problem. I run a small CLEC network that is single homed to BTN for transit. I have 3 sites all interconnected via DS3's and provide DSL services from each site. From anywhere on my network we have problem with Ebay and versiontracker.com but only on certain browsers. IE on a windows machine can access these sites without any problems, but Firefox on the same machine cannot open the websites (Ebay can be opened with addblocking software installed). On a Mac the only browser that works for these sites is Opera. With this knowledge I would say it is something with the coding on the website, but if I take the same machine and connect it to another network other than mine (Verizon, SBC and local municipal wifi have been tested) everything works fine. Can anyone give me any suggestions as to what routes to take to troubleshoot this? Logic tell me that is I have reach ability and one browser work but another doesn't it's a software problem with either the browser or the site, but being able to take the same machine to another network and have it work points to a whole different problem. Could this be a MTU issue? Shane Owens DNA Communications Inc 601 1st Ave Rochelle, IL 61068 work (815)562-4290 ext 201 mobile (815)793-3822
VOIP provider
Not really an operational question, but an engineering question non-the-less. This may also not be the most suitable forum, but there is a large brain trust here that can probably answer my questions. We are looking at a business plan to launch a large VOIP carrier globally. My questions are: 1: Does it make sense to scatter nodes around the globe to limit latency on intraregional calls? If so how many? We were thinking about 7 placed at strategic points around the globe. 2: Is a softswitch architecture preferred to a proxy server/Media Gateway (Vonage) only type architecture? 3: What protocols should be used for firmware upgrades to ATA devices? We are thinking HTTPS or SFTP, or HTTP if those aren't available on selected devices. I am trying to stay away from TFTP for security reasons. 4: Anyone have any vendor recommendations? We currently use Metaswitch for our Softswitch, but I'm not sure it would be the best choice for a large scale deployment although I am going to research it. 5: Should I work with large wholesalers (L3, GX, etc) or try to penetrate markets in some other way? 6: Are there any wholesalers (DID Origination) outside of the US that anyone knows of? Sorry to have so many questions. Many of these I already have ideas on the answers however I acknowledge there are far smarter people than myself in the world. So I figure it's a good idea to ask and get opinions from others before I make a final decision. Shane Shaneowensdna-communications.com
RE: Vonage Selects TCS For VoIP E911 Service
Why not standardize this across the board for all access devices? As an example if my Broadband provider was required to enter location information in my cable modem so that when I connected a VOIP device (ATA, IAD, PC, etc) it would query the first IP device it encountered and gather location data that would solve a lot of these problems. Any solution can be circumvented so no solution will be perfect, but this idea seems easy enough to accomplish with existing technology. It would even fix the VPN connection issue, unless the user was purposefully trying to obfuscate himself in which case I don't think we are necessarily concerned about his ability to contact emergency services.

After that, the VoIP operators and the Wi-Fi access operators should be able to sort out some protocol for sharing the location info. Welcome to the 21st century! They never said it was going to be easy. --Michael Dillon
RE: what will all you who work for private isp's be doing in a few years?
On this I am wondering what the user market would chose with an offer from a DSL provider of a guaranteed bandwidth purchase with a contention based cap on max speed. For example DSL sold with a guaranteed bandwidth availability of 256K (or 512K, 768K etc based on 256K increments) with a "up to" maximum of 7-10Mbps. Would the typical user understand the difference between this the standard Comcast marketing of "up to" speeds without any service guarantee?
