Corporate Internet Access

jscimeca715

I didn't know where to post this, but since it didn't have anything to do with a specific certification I thought I would throw it on here.

How do large corporations get internet access? I'm assuming a company with thousands of users don't use a cable modem? Or do they? I'm a network manager for a small branch office of about ten people so I don't have that exposure yet.

Any help would be great. Thanks!

Usually leased lines through the local ISPs (Verizon, AT&T, Qwest, etc). Can be a fractional, single, or multiple T1 line or T3 lines. Datacenters will have even beefier connections.

Excellent, so T1 and T3 lines for example, don't have to be to another site you own correct? It could be a leased line directly into the ISP's network?

Pretty much. And you have to look at your requirements. We have some sites that have 10 users who only use fractional T1's and it supports there internet and phones fine. We also have a customer who has 10 employees, and they have 3T1's from us why I don't know. But they have them and we route there internet and WAN traffic.

Yeah, it could be either or both. We have a T1 to our ISP for the internet, then we have private T1's that link to different company sites.

Some smaller offices use SDSL. Usually it doesn't have a SLA or a very bad one if it does but it tends to be significantly cheaper than a leased line.

Lets not forget about the ever growing MetroE option.

FiOS is an option as well....I have a 20/20 to my house....they also have a 50/20...

Yup. We're rolling with a 20M MetroE at our main office.

I miss the OC48 pipe from when I worked for a datacenter. The torrents. . . the streaming movies. . . <sigh>

When I worked at a datacenter I had 50MB down at my desk. *sigh*

To answer the OP, like many have stated, it depends on the needs on the company. Some people will use a single DS0 and only pay for 56k CIR, other larger corporations may even be paying for an OC3. It all depends. MetroE is a viable option as well. Speeds between 1MB and 1GB are available depending on the purse strings.

T1's aren't cheap. $400 per month per T1 would be a good price. Depending on what you do, you might need quite a few of them.

Metro Ethernet, FiOS, or Optical Carrier is the way to go if you can get it.
