So I'm working with a guy who MAY want to move a whole lot of data to the NYSE very quickly.

Currently he has a cable modem and a 25 ms. ping.

I was thinking "So we get a T-1" ... but I read on the Googles where T-1 and a cable modem are really about the same?

1] Are T-1 and a cable modem about the same? Up *and* down?

2] If the answer to #1 is yes, how do you get more speed? Move to Manhattan?

Most cable companies offer business service with good speeds and guaranteed uptime. My workplace has a about 45mbits from Road Runner

T1 is dedicated 1.5mb up and down consistantly.

Cable has varying rates but the more people online the slower it gets. The speeds they advertise are burst and they dont hafta deliver that advertised speed.

You might want to look into a OC1 or OC3 connection if money is no object. Or some kind of leased line directly to NYSE if thats all hes using it for.

Let me breakdown the whole cable internet thing.

Cable is a shared bandwidth platform. It automatically detects which users are requiring more bandwidth. If one guy down the street is downloading a 400mb file, the network allocates bandwidth from other users who are inactive to the one guy who is downloading all that stuff. The more bandwidth he has, the faster he can download that file so the network can re-allocate resources to everyone else.

This also goes to gaming traffic, since it is constantly downloading information and sending information, the network will allocate more resources to you depending on how much information you are sending and receiving.

Another thing is the line running to the modem is the first line the drop (the line off the pole coming into your house) leads off to. It is supposed to be dedicated and not split to prevent ingress and interference. This is done to prevent issues with the Internet connectivity and also to make the connection more reliable.

The only downside to cable internet and this is from a cable repair technician is if your homes' cable system is faulty. It isn't often but it happens. I re-wired my house with new cable and ran a new line off the pole and I have never had a problem ever with my Internet. I usually have the lowest ping in game servers and I never lag.

T1 has an upload transfer rate a little higher than cable and it is dedicated, but for about 300 dollars less you could have premium cable internet which is only roughly 500 - 700k less on the upstream but much farther ahead on the downstream.

If the cable network is reliable it is a cheaper alternative to T1 but no matter how clean the cable network is, no matter how perfect the signal level is, it is still a shared-bandwidth platform where as a T1 is not.

Over here T1 is a term used very loosely and pretty much discontinued. If you need to move a whole lot of data to somewhere (like uploading stuff) then you should get a business line from the cable company. Im sure they could offer you a parallel connection, for a price.

I have a friend who pays an absurd amount of money for a T1 line, and in most situations my boring old cable provides me with faster download speeds and often a better ping. The only real advantages are that with a t1 you are unaffected by other users and that you generally get more upload (its parallel) than you would with cable. Not worth the money imo.

T3 on the otherhand might be an interesting option Thats up to about 45mbps both ways (while a t1 maxes out at 1.5mbps both ways). If money was truly no object, I'd go for an OC line. A full OC48 can reach almost 2500mbps...absurd bandwidth...but thats gonna cost you probably a few million dollars per year (probably even more if its going to a residence and not a business or university...an OC3 costs like $250,000 per year, and an OC48 is 16x faster).

Pretty soon my ISP will be offering wideband with their new cisco routers. 100mb up and down baby! All through existing cable lines just a new cable modem that uses three downstreams.

Let's look at it this way. Here are all the options (as I can figure based upon the info you provided)

Leased Line: Leased lines can be had at various speeds from telcos. A T1 is a leased line. So is a T3, OC12, etc. The pros of a leased line is that it is dedicated bandwidth. The contract will normally lay our a service level agreement that dictates a minimum bandwidth and uptime as well as how fast the service will be repaired in the event of a problem. The cons of a leased line are that they are expensive and require equipment installed on both ends. This means that your friend will need to work with NYSE to connect to their network. How feasible that is depends upon his relationship with them and what is going on.

Cable: As mentioned by j-dogg, cable is a shared medium. It also would require that your friend goes over the Internet and connect to NYSE via a VPN of some sort. Both of those, combined with the shared part, make bandwidth a flexible thing. There are no guarantees. Even if the local cable company has a business service with SLAs and such, once you hit the 'net all bets are off.

FIOS: FIOS (which I have) is great. The speeds are excellent (in both directions) and Verizon is now offering a 20/20 service with 20mb up and down. And from a cost perspective it does not cost much more than Cable. The drawback is that you would have to go over the Internet and VPN, which means bandwidth guarantees are not possible.

So a leased line would be the best bet, but requires the cooperation of NYSE to setup the dedicated connection. Knowing the business NYSE is in, I would guess that this kind of setup is not something that is new to them and they have a procedure for allowing someone to connect a leased line to their network. As for what speed line to get, that all depends on how much data he wants to move and how fast it needs to be done. Here is some speed information, all speeds are symetrical (same up and down):

Traditional Leased Lines
T1 = 1.544 Mbps
T3 = 44.736 Mbps

OC Lines (SONNET, Fiber)
OC-1 = 51.84 Mbps
OC-3 = 155.52 Mbps
OC-12 = 622.08 Mbps
OC-48 = 2488 Mbps (yes, that is 2.5Gbps)

And it goes up from there to OC-768 (39.6 Gbps).

Quote: FiOS Packages offering up to 30 Mbps downloads and 5 Mbps uploads (and even higher in some locations)

I really wish this was in my area at 29.99 a month(sale right now) and 39.99 a month normally. I'm sick of charter's horrible service. I hate verison's phone service for the most part, its a love hate thing. However I would grab this in a heart beat.

Is yours through Verison Nervous? (seems to be a verison only thing)

Yeah, FIOS is a Verizon product. I have the TV/Phone/Net deal for $95/month. I then upgraded the TV box to the Multi-Room DVR and got 3 more boxes so I can recored up to two shows at once on the main TV and watch anything recorded on it on any of the other TVs. It's pretty cool and the main reason I got FIOS. I had Optimum Online and the speeds were fine, but they didn't have the multi-room DVR option.

The phone service is normal POTS, not VOIP with Verizon, which I guess is good and bad. What I don't like about it is the voice mail. The only way to know you have a message is to pick up the phone and listen to the dial tone you get. I used to have Vonage and I loved getting an e-mail with the message attached. And the phone told you on the screen that there was a message waiting.

And you have to get all three to get the discounts, otherwise if you got just the TV/Internet it would end up costing almost as much as the 3 services with the discounts.

is this going to be a one time thing or a constant thing?

if its a one time thing.. i would look at going at another route.


for upload speeds, you would need to go t1 --> t3 --> business cable --> fios

to get decent upload speeds. (which pale in comparison to download speeds)

if this is a one time thing, you have to look at all the costs:

monthly cost
installation cost
hardware cost

and you might have to sign a contract.


for a one time deal, go pick up 1 external hdd case, and a bunch of 300gb hdds, it will be cheaper in the long run.

Since they are looking to connect to the NYSE, I am assuming that it involves trading or some sort of security (as in financial instrument) data. As well as bandwidth, latency is of special importance in this case. A few milliseconds can have an impact on the dollar value of a trade. If it's a trading application that he'll be implementing, a dedicated Market Data Feed and direct connectivity to the exchange are paramount. Savvis and Yipes are two well known ISPs in the financial community that can provide direct connectivity to the exchanges. You will definitely pay a premium for their services, however they are at the top of the heap. Feel free to PM or continue with this thread if you have any other questions, I work in this space and know it very well.

See? This is what I absolutely LOVE about PCApex!!!!!!!!!!!!!!!!!!!!!!!!1

I can ask the most obscure questions about computers [about anything] and somebody who has detailed knowledge responds.

I'm gonna rep mrcracker for volunteering and I may get in touch should bandwidth be a issue.
