DS3 Bandwidth..... Perfect For A New Data Network

DS3 Bandwidth delivers the extra capacity and worry free reliability any company requires to support critical business functions. It'll make every IT specialist breathe a sigh of relief once implemented ... and when made the center piece of your pitch to management should give you confidence that you network proposal will be accepted without a hitch.

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.... the most 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. Also, it may be that you need massive files "right now" so you will have to go for the bigger line connections. By bigger I mean DS3 bandwidth or possibly OC3 bandwidth.... instead of say a full or fractional T1 line.

In other words do your homework so you're confident you can answer any question asked.

Now ...... 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 (Quality of Service) mechanisms to make sure that bandwidth was available for other applications.

DS3 based bandwidth solutions are often used for corporate-hosted application servers, real time video transport (such as video conferencing), high resolution images (think medical imagery), large engineering files (such as 3D modeling or CAD) and data backups to remote data centers. You can get this level of bandwidth through either fiber optic delivery or over copper coaxial lines (also called T3 lines). Remember too that DS3 isn’t just for data. A DS-3 can be channelized to deliver voice as well as data.

For comparison purposes …. the capacity or speed of a DS3 is the equivalent of twenty-eight (28) T1 lines. To be more specific ….. a typical DS3 network is capable of transmitting 44.7 million bits per second upstream and downstream. Normally, a DS3 dedicated broadband line has about 672 voice and data channels. Each channel has a 64 kpbs capacity with each parallel network connection improving the link speed beyond any single cable or port. Applying DS3 transport over a point to point network (or MPLS – Multi-Protocol Label Switching) makes it possible for your business to include bandwidth intensive applications like those mentioned above for transmission across a busy network.

Here’s a tip …. in Wide Area Networking (WAN) systems bandwidth and application optimization make for better efficiency and performance. For example, utilizing the new 3G Wireless WAN interface in conjunction with DS3 technology will impact the Trunk Line 3 services positively. With this configuration It is possible for you to have hassle free, secure, unlimited internet connectivity for transmission of large amounts of data even more quickly and efficiently.

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. Notice I said .... maybe. 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 .... you may want to 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. You can of course run DS3 through a MPLS network.

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 through ……
