Fair Access Policy (FAP)

Qulaity of Service (QOS) is provided to all users by limiting the heavy users of a shared

resource. Direcway limits the heavy users through their Fair Access Policy (FAP). Under

the many service plans think of each one as a bucket. If you have a full 5 gallon bucket

and you add another teaspoon of something to it then a teaspoon of the something will

flow off the side and be lost. Consumers have a 300MB bucket. Every second Direcway

adds 56Kbps to this 300MB bucket. If the bucket is full you loose the added 56Kbps and

you have a full 300MB bucket. Let us say you start downloading a 500MB file. You will

start a process that drains your bucket at 400Kbps. Since only 56Kbps is being added we

can see that very soon your bucket will become empty. Once it does empty you will only

be able to download at 56Kbps refresh rate. This situation is called FAPed by Direcway

users. You will continue at 56Kbps until the file completes the download and your bucket

begins to fill back up again to the 300MB limit.

People that download a lot of videos and music have turned to products such as

FAPGUARD to control this flow of information and avoid the FAP penalty.

To determine if you have been FAP’ed you can go to the http://www.mydirecay.com web

site and select the “CHECK MY USAGE” item in the “HELP CENTER”. The resultant

report will contain a column of “SUBJECT TO FAP”.
