<div><p>Often additional bandwidth is required to complete certain tasks
|
||
|
|
but is not required all of the time.</p>
|
||
|
|
<div class="section"><p>In these cases the purchase of specialized hardware and expensive
|
||
|
|
communication lines might not be justified. The PPP Multilink Protocol (MP)
|
||
|
|
groups multiple PPP links together to form a single virtual link or "bundle".
|
||
|
|
The aggregation of multiple links increases the total effective bandwidth
|
||
|
|
between two systems by using standard modems and telephone lines. You can
|
||
|
|
include up to Six links in a MP bundle. To establish a Multilink connection
|
||
|
|
both ends of the PPP link must support the Multilink protocol. The Multilink
|
||
|
|
protocol is documented as a Request For Comment (RFC) standard RFC1990. More
|
||
|
|
information about RFCs can be found on the <a href="http://www.rfc-editor.org" target="_blank">RFC Editor</a> Web page.</p>
|
||
|

</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Bandwidth On Demand:</h4><p>The ability to dynamically
|
||
|
|
add and remove physical links allows a system to be configured to supply bandwidth
|
||
|
|
only when it is needed. This approach is commonly referred to as "Bandwidth
|
||
|
|
on Demand" and allows you to only pay for the additional bandwidth when you
|
||
|
|
actually use it. To realize the benefits of "Bandwidth on Demand", at least
|
||
|
|
one peer must be capable of monitoring utilization of the total bandwidth
|
||
|
|
currently in a MP bundle. Links can then be added to or removed from the
|
||
|
|
bundle when bandwidth utilization exceeds values defined by configuration.
|
||
|
|
The Bandwidth Allocation Protocol allows peers to negotiate adding and removing
|
||
|
|
links in a MP bundle. RFC2125 documents both the PPP Bandwidth Allocation
|
||
|
|
Protocol (BAP) and Bandwidth Allocation Control Protocol (BACP).</p>
