Hi,

I would appreciate if anyone could help me out with my research. What kinda of network connectivity (total Gbps and breakdown) do the following ISPs have:

- @HOME
- AOL
- AT&T
- BBN
- Cable & Wireless
- DIGEX
- PSI
- Sprint
- Teleglobe
- UUNET
- Verio

... appreciate it :D !!!

I actually did research on these companies not too long ago when we needed another transit provider. What we looked at was not how much throughput, etc., but how many hosts were directly connected to them, in order to keep the hops down.

Total bandwidth can be measured in different ways, they'll tell you how much fiber they have on their national backbone networks, but that OC-XX figure is the total capacity, not related to what they are actually using, and how that related to their available bandwidth (i.e. capacity is an OC-3 (155Mbps, they are using 4Mbps, and their average network traffic utilizes X% of that 4Mbps). They'll give you the OC-XX info, but the rest is not readily available.

Best connected, and no issues regarding bandwidth on their backbone networks:

Cable & Wireless (but they'll rip you off blind with billing problems-we've used them twice and learned our lesson)

UUNet (they used to be the ISP's ISP, but their quality of service is really slipping (and at $2500 for a T1's worth of transit, that has become unacceptable)

Verio (we were their first customer, and they provide excellent transit, but after they breached our original contract and took back thousands of IP addresses to streamline their recordkeeping processes, we didn't renew)

Digex (we've only been using them since the first of the year, but except for having to train their engineers on how to set things up on their end for them to run BGP with us, the've been very good)

PSInet (we considered them, but as their top managment had just decamped at that time, decided that we didn't want to sign a contract with them-they are currently teetering on the edge of bankruptcy)

The rest are more for consumers and businesses not ISP's, so we didn't consider them seriously. AT&T and Sprint are both well connected, but their sales people didn't understand the concept of multihoming or the fact that we wanted transit from our backbone to theirs.

Anyone got any good insider info on these companies?

although you might not have the info on available bandwidth or what they are actually using, but do you know how much total fiber they (CW, UUNET, Verio, Digex, AT&T, and Sprint) have on their national backbone networks in the usa and internationally (breakdown would be nice :D)

My ISP is Bell. They have a good uptime. Once in a while, there is a 2 hours network maintaince. Other than that, I notice no downtime.

klisis, i am doing research on isps (with a customer base of at least 100,000) and their network connectivity and including the ones listed above

if anyone has solid numbers of how much total fiber they have on their national backbone networks in the usa and internationally, that would be nice

Bell, the telephone company, is one of major ISP in Canada. I think bell got more than 100.000. I am not sure how I would obtain information about their fiber.

This isps are so big that it depends on your location to find who is better for you.

AbuHasan, that is not the point of my research.

It's simply to find out their network connectivity and how much total fiber (just raw numbers) they have on their national backbone networks in the usa and internationally ~ breakdown, etc.

Numbers of total fiber on a company's backbone are usually made public, in order to mislead. That information should be on the company's website, it was when i was doing my research for a new transit provider, but i ignored that information. It's normally exponentially larger than what is actually in use, and is used strictly for marketing purposes.

Our total fiber on our local Internet backbone is an OC-12. That's what Verizon installed when they lighted our building with fiber. But our bandwidth usage is only a fraction of that. And because we dont believe in misleading, we don't say we have an OC-12.
