<p class=MsoNormal>The following new features have been added to OpenSIPS:<o:p></o:p></p>

<p class=MsoNormal>1. Generic AAA API<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>The AAA API represents a set of generic callbacks and
structures needed<o:p></o:p></p>
<p class=MsoNormal>for AAA operations.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>The purpose of the API is to move all the AAA specific (Radius)
implementations<o:p></o:p></p>
<p class=MsoNormal>in a single module. The AAA API will hide the
implementations details from the<o:p></o:p></p>
<p class=MsoNormal>modules that want to use AAA support, making it easier to
use.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>Currently, only one module implements the AAA API -
aaa_radius, offering Radius<o:p></o:p></p>
<p class=MsoNormal>support.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>Because both standardized AAA protocols, Radius and
Diameter, use lists of<o:p></o:p></p>
<p class=MsoNormal>attribute-value pairs, the API is designed based on
attribute-value pairs, as well.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>One of the advantages of using the API is that any module
that wishes to do<o:p></o:p></p>
<p class=MsoNormal>AAA operations does not depend on a certain protocol
implementation, therefore<o:p></o:p></p>
<p class=MsoNormal>it is not linked with a certain AAA library.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>Hence, any module that was previously using Radius, for
example, is not<o:p></o:p></p>
<p class=MsoNormal>linked with the radiusclient library any more, which is obviously
an advantage,<o:p></o:p></p>
<p class=MsoNormal>especially when the module uses more than one API (DB, AAA,
etc).<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>The AAA protocol to be used by a module is specified from
the script using a<o:p></o:p></p>
<p class=MsoNormal>so called "aaa_url" that encodes the protocol used
and other useful information<o:p></o:p></p>
<p class=MsoNormal>depending on the protocol.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>The way the generic AAA API is used makes it very similar to
the generic<o:p></o:p></p>
<p class=MsoNormal>database API.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>2. The ability to make custom Radius requests directly from
the script<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>This feature is very useful because of its flexibility.
Basically, any type<o:p></o:p></p>
<p class=MsoNormal>of Radius queries can be yielded directly from the script,
and also, Radius<o:p></o:p></p>
<p class=MsoNormal>replies can be inspected for certain attributes.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>3. Radius implementation for the generic AAA API<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>The handling of Radius AVP "SIP-AVP" (used for
fetching variables from the<o:p></o:p></p>
<p class=MsoNormal>Radius server) was integrated in this module. All SIP-AVPs
are automatically<o:p></o:p></p>
<p class=MsoNormal>and transparently handled by the module, so that this
functionality is by default<o:p></o:p></p>
<p class=MsoNormal>available for all the modules that use Radius.<o:p></o:p></p>
<blockquote style='border:none;border-right:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;
margin-left:4.8pt;margin-right:0in'>

margin-left:4.8pt;margin-right:0in'>
<p class=MsoNormal><o:p> </o:p></p>
</blockquote>
<p class=MsoNormal>Due to the fact that the modules that were previously using
Radius were ported<o:p></o:p></p>
<p class=MsoNormal>to the generic AAA API, the following changes have been
made:<o:p></o:p></p>
<p class=MsoNormal>- auth_radius became auth_aaa<o:p></o:p></p>
<p class=MsoNormal>- group_radius was merged with group<o:p></o:p></p>
<p class=MsoNormal>- uri_radius was merged with uri <o:p></o:p></p>
