Limiting Data Transfer

Reducing Data Transfers Amount:
you can reduce your transfer amount by;
1) building simpler websites.
2) more efficient websites.
3) optimizing graphics.
4) Remove unwanted tags, white space and comments.
5) Capitalize on CSS, call java script externally instead of embedding in every page.
6) Do not use too many keywords.

Alternatively, Avoid fancy flash presentations or streaming audio. Limit your META tags to those absolutely necessary. Besides many search engines will only review the first few and ignore the rest.
Another good idea is to cache your website but you might want to set an expiry date in the HTTP headers so the browser will refresh the content after a certain time. Use mod-gzip. It could save you as much as 40% of your bandwidth. Out of control robots can also suck down your bandwidth like a black hole. So use robots.txt to keep spiders in check.

Bandwidth or Data Transfer

People often associate bandwidth with data transfer but all together they are different from each other. But however they have close connections. Bandwidth is how much data can be transferred at a time and data transfer is how much data is being transferred. Or in other words Bandwidth is the technology and data transfer is the gateway for bandwidth.
How It Affects Your Site:
Bandwidth and site uploading has direct relationship.That is,The less bandwidth you have, the slower your site takes to load . If you have more visitors, some of them will have to wait their turn. The least data transfer you have, the more often you’ll find your site unavailable because you’re reached the maximum allowed until a new month rolls by or you upgrade your account.

Determining Your Requirements:
Usually when a host talks about bandwidth, they are referring to your transfer. Hence its purely your assumption of choosing the required amount of bandwidth for your website. Most of this information is available from your traffic history. If you don’t have an existing site, provide an optimistic estimate if you intend to heavily promote the site. You can also do some of daily calculations on your website by;

Find out the daily averages of

Number of visitors / expected number of visitors
Page size including the graphics of the page
Page views / expected pages viewed by each visitor

Then, multiply them as follows:
Visitors x Page size x Page views x 30 days = Monthly Website Transfer
You should also throw in a small margin or error there to take into account email traffic and your own uploads to the server. If you offer downloads, then you should add the following:
Average/Expected downloads x File Size x 30 days = Monthly Download Transfer.

Types of Bandwidth

1. Upstream and Downstream Bandwidth

Upstream type of Bandwidth, also called Upload Bandwidth determines the amount of data that can be sent (uploaded) to the Internet. This is very important for transmitting data and uploading files to the server.

Downstream or Download type of Bandwidth determines the amount of data that is received from the Internet. This is important for downloading the files from the Internet.

2. Basic Consumer Bandwidth, LAN Bandwidth, WAN Bandwidth solutions

Basic Consumer Internet access is most commonly provided by Dial-Up, DSL or Cable connections. Each of these types of connections allows certain amount of data to be transmitted in a fixed amount of time. For a Bandwidth rate of any of these connections check types of connections
LAN (Local Area Network) stands for a group of computers and associated devices that share a common communications line or wireless link. A local area network may have as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network). The most widely used local area network connection technology is Ethernet. Others areToken Ring technology, FDDI and ARCNET. LAN can also use wireless technology. Bandwidth allowed in a specific LAN community depends on the type of connection technology used.

For Ethernet Bandwidth rate check types of connections

WAN (Wide Area Networks) are connections between business organizations and the outside world. A WAN may also be part of a private network that extends across multiple business locations in a city, across the country or even worldwide. Typically WAN represents LAN of the certain organization connected to the outside world. The most common WAN connection is a T1 line. In order to expand Bandwidth multiple T1 lines may be bond together. Another high bandwidth protocol for business connectivity is DS3 over fiber optic SONET service or a T3 line. One of the most popular solutions is Ethernet. Ethernet that runs on LAN can be extended to the WAN. In order to use WAN Ethernet you need to be in a building which a fiber optic cable has been run into and the carrier facilities are installed or at least you have to be near enough to get connected.

Importance of Bandwidth

Bandwidth is a term which is very important in web hosting. It basically means within a given amount of time how much data moves across the network. Basically the time period is for one month. The companies charge from the web hosters monthly or annually.

It is hard to calculate the bandwidth used by the websites due to variations among different web hosting companies. For eg: If just one visitor visits average of 4 pages per month then that means website is having 5000 unique visitors every month.

If we work on simple web pages then they consume very less amount of bandwidth but when we download some files like .mp3,.wav then a large amount of bandwidth is used. Because if the bandwidth is not proper then there will be a problem in downloading your content from the particular website whereas in some cases the sites get hanged up is the user’s bandwidth is not proper.

The bandwidths are provided by the web hosting company according to the usage of the website or the contents that are being used by the website. If the companies use the maximum bandwidth then they will be shuttled down. By keeping this fact in mind the web hosting companies provide the bandwidth accordingly and decide the price.

Customers can have a complete idea of the bandwidth required if he knows how to manage the accounts. If the user has taken small bandwidth and he is providing high value contents like music, video and games then his site will definitely hanged. If the user does not have the idea of the amount of bandwidth he requires for the website then he can face a great problem. The user should be well aware of the charges for the bandwidth which he is getting and should always keep a cost factor in mind while deciding the bandwidth he needs.
