Please note that this feature will only work with Enterprise data file. 51Degrees allows your website to determine how much bandwidth a client has, allowing you to take advantage of a fast connection, or be conservative with a very slow one.

To monitor bandwidth you should include the following the script:

										
										<script 
										
										
										src=
										
										
										"51Degrees.core.js.php"
										
										
										></script>
										
										
										<script>
										
										
										new
										
									 FODBW();

										
										</script>
										
									

Including this script will fill the $_51d array with the following values:

• LastResponseTime (Integer - milliseconds) - The time taken for the web page to start rendering after the user initiated the request.
• LastCompletionTime (Integer - milliseconds) The time taken for the web page to complete rendering after the user initiated the request.
• AverageResponseTime (Integer - milliseconds) The average time taken for the page to start rendering after the user initiated the request during the previous 5 minutes.
• AverageCompletionTime (Integer - milliseconds) The average time taken for the page to complete rendering after the user initiated the request during the previous 5 minutes.
• AverageBandwidth (Integer - bytes / second) The effective average bandwidth of the connection as measured by the amount of HTML data sent and received. The value will vary from a network level inspection as it does not include the TCP or HTTP overhead. It should be used as a guide to the available effective bandwidth. The time values are of more practical use to developers.
