DS3 Bandwidth ..... The Best Connection Configuration For A New Data Network

If your company finds itself in a situation where you are designing a new ..... or even replacement or expansion of an existing high capacity/high load data network .... a logical decision is to consider DS3 bandwidth for your network backbone.

However, to be confident in that decision I recommend first doing the math for the files you project to move ..... and then pick the technology that will work. Even though you need a lot of bandwidth, do you need it continuously or in bursts? It may be that you can transfer files over time instead of all at once so you won't have to get such large pipes. However, it may also be that you need massive files *right now* so you will have to go for the bigger connections. By bigger I mean DS3 bandwidth or possibly OC3 bandwidth.... instead of say a full or fractional T1 line.

So, approach this network analysis with an equation like:

Let's say you have 50 1GB files that need to be transferred every day from point A to B. That's 50 GB in a 24-hour period.

50GB = 400Gb = 400,000,000,000 bits

1 day = 86400 seconds

400,000,000,000/86400 = ~4700000 bits/sec = ~ 5 Mb/sec

Of course, that would be going full bore 24 hours a day with no protocol overhead, so you are realistically looking at doubling that number. Then, you could put in some additional QOS mechanisms to make sure that bandwidth was available for other applications.

If you are in a local metro area where providers can service your building(s) with ethernet service to all your offices ..... that may be cheaper than getting a TDM circuit such as a DS-3 line. If they cannot serve all your locations with "on-net" ethernet service then perhaps you can look for a burstable DS-3 or tiered pricing plan to save costs ..... and only pay for the bandwidth you will be using on average.

Also look into using MPLS VPN service instead of a dedicated point to point. It is typically a more cost effective solution to establish IP connectivity between "x" number of offices.

Since you likely will have large files to move such as 3D modeling, CAD, or medical imagery ..... if the data transmission is TCP based, then I also suggest to look into some WAN acceleration appliances such as Riverbed, Cisco WAAS, or Juniper WX. This will allow you to take advantage of the pipe (bandwidth) size you have. It will also allow you to cache commonly transmitted bits to save bandwidth costs and utilize your WAN circuits efficiently ..... while improving end-user application performance over the WAN. Since those appliances simulate LAN performance with the built-in algorithms.

If all that explanation is making your head spin .... there's a way you can make the entire process much simpler. To accomplish this I recommend taking advantage of the free consultative services available to you here:
