<title>What is volume accounting?</title>
|
||
|
|
|
||
|
|
<para>Basically, it means to count the number of bytes transmitted to and from
|
||
|
|
the Internet. &kppp; can count incoming bytes, outgoing bytes, or both. It's
|
||
|
|
up to you what you want (or must) use.</para>

<title>Why should I use volume accounting?</title>
|
||
|
|
|
||
|
|
<para>Many Internet Service Providers bill their customers based on the number
|
||
|
|
of bytes transferred. Even more commonly, <acronym>ISP</acronym>'s offer a flat
|
||
|
|
rate up to some arbitrary transfer limit, and then charge more for every
|
||
|
|
megabyte above this limit. &kppp; shows you your current volume and can help
|
||
|
|
you keep your bills to the minimum. Of course, even if you're not billed based
|
||
|
|
on volume, you can turn on volume accounting just to satisfy your own
|
||
|
|
curiosity.</para>

<title>What type of volume accounting should I select?</title>
|
||
|
|
|
||
|
|
<para>That depends mainly on your provider. Many of them only count how many
|
||
|
|
megabytes you download from the Internet,and ignore how much you send. In that
|
||
|
|
case you should choose <guilabel>Bytes In</guilabel>. If you have to pay for
|
||
|
|
both, you should choose <guilabel>Bytes In and Out</guilabel>. <guilabel>Bytes
|
||
|
|
Out</guilabel> is really only here for completeness, as we're not aware of any
|
||
|
|
providers using it as a billing basis. It might be useful to those of you
|
||
|
|
running a web or &FTP; server at home though.</para>

<title>Drawbacks</title>
|
||
|
|
|
||
|
|
<para>Unfortunately, there is a drawback on volume accounting. &kppp; will only
|
||
|
|
count the number of bytes, regardless of their origin. Many providers set their
|
||
|
|
limit only for Internet access, and not for data on their own network. Some
|
||
|
|
providers set different limits for data that is on their own network, in the
|
||
|
|
same country, and coming from overseas. So, if you're doing not much
|
||
|
|
websurfing, and getting most of your pages from your <acronym>ISP</acronym>'s
|
||
|
|
own proxy cache, then your provider is probably not charging you for that data.
|
||
|
|
&kppp; will not know these <acronym>IP</acronym> packets are coming from the
|
||
|
|
proxy, and so it will count them. So if you this situation applies to you, or,
|
||
|
|
as another example, your provider uses a caching news server such as
|
||
|
|
<application>nntpcached</application>, then the volume reported by &kppp; may be
|
||
|
|
higher than the amount you are going to be billed for. On the bright side, at
|
||
|
|
least &kppp; will never underestimate your bills.</para>
