Summary:
Bandwith Explained
Dedicated Bandwidth
This is bandwidth that is from your network direct to the Internet Backbone. This is very expensive, as by definition, it is dedicated to you and not allowed to be used by anyone else.
Advantages:
| » |
Whenever you require the bandwidth it is always there. |
| » |
You are more able to execute other types of operations through your link such as voice. |
Disadvantages:
| » |
It is expensive as your monthly charge may be fixed, but it will be higher that the rates of managed as the bandwidth is dedicated to only you. Thus it is understood that you will be wasting a lot of bandwidth also as there is no way any network can sustain 100% usage 24 hours a day. This can be compensated by good usage in working hours for critical applications. |
Managed Bandwidth
This is bandwidth that you get to the Internet Service Provider where it is managed (shared) with other users. The actual bandwidth you will get at any one time depends on the number of concurrent users on the network of the ISP in relation to the total bandwidth that the ISP has.
Advantages
| » |
It is cheaper as your provider will attempt to manage many users on the same bandwidth so that as little bandwidth as possible is wasted. |
| » |
You are able to afford a larger Internet link up to your ISP (but not necessarily to the Internet). |
Disadvantages
| » |
You are not guaranteed bandwidth although some ISPs will tell you what percentage of your link you are guaranteed if the entire user base were simultaneously using the Internet link – Although this is an unlikely event. |
| » |
If you have mission critical application then it is preferred that you take dedicated bandwidth with some level of burst ability through a sharing program that the ISP has. For example 512 burstable to 1024. Which implies that you are guaranteed 512 but on demand the network will be able to offer you 1024 if bandwidth is available. |
