+
+1. Overview
+
+   CDP (C Diameter Peer) allows Diameter communication to and from
+   sip-router/kamailio. Most of the code is inherited from DISC
+   http://developer.berlios.de/projects/disc/ and OpenIMS and modified for
+   use within Kamailio. A few improvements/new functionality has been
+   added along the way, for example, threshold reporting on Diameter calls
+   that are serviced above a certain threshold.
+
+2. How it works
+
+   CDP forks the following processes:
+     * 1 x Timer
+     * 1 x Acceptor
+     * k x Workers (k configurable through configuration)
+     * i x Receivers (one for each peer plus one for unknown peers)
+
+   CDP is really only an API and offers all of its methods to other
+   modules. No commands are made available to the main Kamailio
+   configuration file. The exported API can be seen in mod.c. The Full
+   Diameter API is in diameter.h and diameter_api.h. IMS-specific
+   constants can be found in diameter_ims.h. The protocol coding is
+   implemented in diameter_avp.c and diameter_msg.c. Diameter state
+   machine is implemented in peerstatemachine.c - there is one of these
+   for each peer which maintains all protocol/application state for each
+   peer. peermanager.c is responsible for peer administration. Diameter
+   transactions are implemented in transaction.c.
+
+   There are 2 configuration areas for CDP. Firstly it must be loaded and
+   conifugred in the Kamailio.cfg file (this is the normal task associated
+   with Kamailio modules). Then, an XML file is required to configure
+   various Diameter parameters and all related peers and the associated
+   routes.

+6. Configuration Examples
+
+   6.1. DiameterPeer.xml example
+   6.2.
+
+6.1. DiameterPeer.xml example
+
+   This is an example CDP configuration file. The location of this file is

+<!--
+
+ DiameterPeer Parameters
+  - FQDN - FQDN of this peer, as it should apper in the Origin-Host AVP
+  - Realm - Realm of this peer, as it should apper in the Origin-Realm AVP
+  - Vendor_Id - Default Vendor-Id to appear in the Capabilities Exchange
+  - Product_Name - Product Name to appear in the Capabilities Exchange
+  - AcceptUnknownPeers - Whether to accept (1) or deny (0) connections from peer
+s with FQDN
+    not configured below
+  - DropUnknownOnDisconnect - Whether to drop (1) or keep (0) and retry connecti
+ons (until restart)
+    unknown peers in the list of peers after a disconnection.
+  - Tc - Value for the RFC3588 Tc timer - default 30 seconds
+  - Workers - Number of incoming messages processing workers forked processes.
+  - Queue - Length of queue of tasks for the workers:
+     - too small and the incoming messages will be blocked too often;
+     - too large and the senders of incoming messages will have a longer feedbac
+k loop to notice that
+     this Diameter peer is overloaded in processing incoming requests;
+     - a good choice is to have it about 2 times the number of workers. This wil
+l mean that each worker
+     will have about 2 tasks in the queue to process before new incoming message
+s will start to block.
+  - ConnectTimeout - time in seconds to wait for an outbound TCP connection to b
+e established.
+  - TransactionTimeout - time in seconds after which the transaction timeout cal
+lback will be fired,
+    when using transactional processing.
+  - SessionsHashSize - size of the hash-table to use for the Diameter sessions.
+When searching for a
+    session, the time required for this operation will be that of sequential sea
+rching in a list of
+    NumberOfActiveSessions/SessionsHashSize. So higher the better, yet each hash
+slot will consume an
+    extra 2xsizeof(void*) bytes (typically 8 or 16 bytes extra).
+  - DefaultAuthSessionTimeout - default value to use when there is no Authorizat
+ion Session Timeout
+  AVP present.
+  - MaxAuthSessionTimeout - maximum Authorization Session Timeout as a cut-out m
+easure meant to
+  enforce session refreshes.

+ DiameterPeer Parameters 
+  - FQDN - FQDN of this peer, as it should apper in the Origin-Host AVP
+  - Realm - Realm of this peer, as it should apper in the Origin-Realm AVP
+  - Vendor_Id - Default Vendor-Id to appear in the Capabilities Exchange
+  - Product_Name - Product Name to appear in the Capabilities Exchange 
+  - AcceptUnknownPeers - Whether to accept (1) or deny (0) connections from peers with FQDN 
+    not configured below
+  - DropUnknownOnDisconnect - Whether to drop (1) or keep (0) and retry connections (until restart)
+    unknown peers in the list of peers after a disconnection.
+  - Tc - Value for the RFC3588 Tc timer - default 30 seconds
+  - Workers - Number of incoming messages processing workers forked processes.
+    This only matters in ser_ims.
+    In Wharf, the Wharf workers pool are reused for this purpose.
+   - Queue - Length of queue of tasks for the workers:
+     - too small and the incoming messages will be blocked too often;
+     - too large and the senders of incoming messages will have a longer feedback loop to notice that
+     this Diameter peer is overloaded in processing incoming requests;
+     - a good choice is to have it about 2 times the number of workers. This will mean that each worker
+     will have about 2 tasks in the queue to process before new incoming messages will start to block.
+  - ConnectTimeout - time in seconds to wait for an outbound TCP connection to be established.
+  - TransactionTimeout - time in seconds after which the transaction timeout callback will be fired,
+    when using transactional processing.
+  - SessionsHashSize - size of the hash-table to use for the Diameter sessions. When searching for a 
+    session, the time required for this operation will be that of sequential searching in a list of 
+    NumberOfActiveSessions/SessionsHashSize. So higher the better, yet each hashslot will consume an
+    extra 2xsizeof(void*) bytes (typically 8 or 16 bytes extra).
+  - DefaultAuthSessionTimeout - default value to use when there is no Authorization Session Timeout 
+  AVP present.
+  - MaxAuthSessionTimeout - maximum Authorization Session Timeout as a cut-out measure meant to
+  enforce session refreshes.

+ * The initial version of this code was written by Dragos Vingarzan
+ * (dragos(dot)vingarzan(at)fokus(dot)fraunhofer(dot)de and the
+ * Fruanhofer Institute. It was and still is maintained in a separate
+ * branch of the original SER. We are therefore migrating it to
+ * Kamailio/SR and look forward to maintaining it from here on out.
+ * 2011/2012 Smile Communications, Pty. Ltd.
+ * ported/maintained/improved by 
+ * Jason Penton (jason(dot)penton(at)smilecoms.com and
+ * Richard Good (richard(dot)good(at)smilecoms.com) as part of an 
+ * effort to add full IMS support to Kamailio/SR using a new and
+ * improved architecture
+ * 
+ * NB: Alot of this code was originally part of OpenIMSCore,
+ * FhG Focus. Thanks for great work! This is an effort to 
+ * break apart the various CSCF functions into logically separate
+ * components. We hope this will drive wider use. We also feel
+ * that in this way the architecture is more complete and thereby easier
+ * to manage in the Kamailio/SR environment

+
+  <section>
+    <title>Overview</title>
+
+    <para>CDP (C Diameter Peer) allows Diameter communication to and from
+    sip-router/kamailio. Most of the code is inherited from DISC
+    http://developer.berlios.de/projects/disc/ and OpenIMS and modified for
+    use within Kamailio. A few improvements/new functionality has been added
+    along the way, for example, threshold reporting on Diameter calls that are
+    serviced above a certain threshold.</para>
+  </section>
+
+  <section>
+    <title>How it works</title>
+
+    <para>CDP forks the following processes:</para>
+
+    <itemizedlist>
+      <listitem>
+        <para>1 x Timer</para>
+      </listitem>
+
+      <listitem>
+        <para>1 x Acceptor</para>
+      </listitem>
+
+      <listitem>
+        <para>k x Workers (k configurable through configuration)</para>
+      </listitem>
+
+      <listitem>
+        <para>i x Receivers (one for each peer plus one for unknown
+        peers)</para>
+      </listitem>
+    </itemizedlist>
+
+    <para>CDP is really only an API and offers all of its methods to other
+    modules. No commands are made available to the main Kamailio configuration
+    file. The exported API can be seen in mod.c. The Full Diameter API is in
+    diameter.h and diameter_api.h. IMS-specific constants can be found in
+    diameter_ims.h. The protocol coding is implemented in diameter_avp.c and
+    diameter_msg.c. Diameter state machine is implemented in
+    peerstatemachine.c - there is one of these for each peer which maintains
+    all protocol/application state for each peer. peermanager.c is responsible
+    for peer administration. Diameter transactions are implemented in
+    transaction.c.</para>
+
+    <para>There are 2 configuration areas for CDP. Firstly it must be loaded
+    and conifugred in the Kamailio.cfg file (this is the normal task
+    associated with Kamailio modules). Then, an XML file is required to
+    configure various Diameter parameters and all related peers and the
+    associated routes.</para>

+
+ DiameterPeer Parameters 
+  - FQDN - FQDN of this peer, as it should apper in the Origin-Host AVP
+  - Realm - Realm of this peer, as it should apper in the Origin-Realm AVP
+  - Vendor_Id - Default Vendor-Id to appear in the Capabilities Exchange
+  - Product_Name - Product Name to appear in the Capabilities Exchange 
+  - AcceptUnknownPeers - Whether to accept (1) or deny (0) connections from peers with FQDN 
+    not configured below
+  - DropUnknownOnDisconnect - Whether to drop (1) or keep (0) and retry connections (until restart)
+    unknown peers in the list of peers after a disconnection.
+  - Tc - Value for the RFC3588 Tc timer - default 30 seconds
+  - Workers - Number of incoming messages processing workers forked processes.
+  - Queue - Length of queue of tasks for the workers:
+     - too small and the incoming messages will be blocked too often;
+     - too large and the senders of incoming messages will have a longer feedback loop to notice that
+     this Diameter peer is overloaded in processing incoming requests;
+     - a good choice is to have it about 2 times the number of workers. This will mean that each worker
+     will have about 2 tasks in the queue to process before new incoming messages will start to block.
+  - ConnectTimeout - time in seconds to wait for an outbound TCP connection to be established.
+  - TransactionTimeout - time in seconds after which the transaction timeout callback will be fired,
+    when using transactional processing.
+  - SessionsHashSize - size of the hash-table to use for the Diameter sessions. When searching for a 
+    session, the time required for this operation will be that of sequential searching in a list of 
+    NumberOfActiveSessions/SessionsHashSize. So higher the better, yet each hashslot will consume an
+    extra 2xsizeof(void*) bytes (typically 8 or 16 bytes extra).
+  - DefaultAuthSessionTimeout - default value to use when there is no Authorization Session Timeout 
+  AVP present.
+  - MaxAuthSessionTimeout - maximum Authorization Session Timeout as a cut-out measure meant to
+  enforce session refreshes.

+                information is sent as part of the Capabilities Exchange procedures on connecting to
+                peers. If no common application is found, the peers will disconnect. Messages will only
+                be sent to a peer if that peer actually has declared support for the application id of

+
+        &lt;!--
+                Realm routing definition.
+                Each Realm can have a different table of peers to route towards. In case the Destination
+                Realm AVP contains a Realm not defined here, the DefaultRoute entries will be used.
+
+                Note: In case a message already contains a Destination-Host AVP, Realm Routeing will not be
+                applied.
+                Note: Routing will only happen towards connected and application id supporting peers.
+                
+                The metric is used to order the list of prefered peers, while looking for a connected and
+                application id supporting peer. In the end, of course, just one peer will be selected.

+ * branch of the original SER. We are therefore migrating it to
+ * Kamailio/SR and look forward to maintaining it from here on out.
+ * 2011/2012 Smile Communications, Pty. Ltd.
+ * ported/maintained/improved by 
+ * Jason Penton (jason(dot)penton(at)smilecoms.com and
+ * Richard Good (richard(dot)good(at)smilecoms.com) as part of an 
+ * effort to add full IMS support to Kamailio/SR using a new and
+ * improved architecture
+ * 
+ * NB: Alot of this code was originally part of OpenIMSCore,
+ * FhG Focus. Thanks for great work! This is an effort to 
+ * break apart the various CSCF functions into logically separate
+ * components. We hope this will drive wider use. We also feel
