<p>
The table below summarizes the diameter application's compliance with
&the_rfc;.
Since the diameter application isn't a Diameter node on its own,
compliance is strictly the responsibility of the user in many cases,
diameter providing the means for the user to be compliant
rather than being compliant on its own.</p>
<p>
The Compliance column notes <em>C</em> (Compliant) if the required
functionality is implemented, <em>PC</em> (Partially Compliant) if
there are limitations, <em>NC</em> (Not Compliant) if functionality is
not implemented, or a dash if text is informational or only places
requirements that must be met by the user's implementation.</p>
<p>
Capitalized <em>Diameter</em> refers to the protocol, lowercase
<em>diameter</em> to the Erlang application.</p>

Ready dictionaries are provided for the &the_rfc; common message, base

<cell>Protocol Overview</cell>
<cell>&NA;</cell>
<cell>Session state is the responsibility of the user.&BR;
The role of a Diameter node is determined by the user's
implementation.</cell>
</row>
<row>
<cell>2.1</cell>
<cell>Transport</cell>
<cell>PC</cell>
<cell>Ports are configured by the user: diameter places no
restrictions.&BR;
The transport interface documented in &man_transport;
allows the user to implement their own methods.
Ready support is provided for TCP, TCP/TLS, and SCTP, but not
DTLS/SCTP.&BR;
Multiple connections to the same peer is possible.
ICMP messages are not interpreted.</cell>
</row>
<row>
<cell>2.1.1</cell>
<cell>SCTP Guidelines</cell>
<cell>C</cell>
<cell>Unordered sending is configurable in &man_sctp;.
There is no special handling of DPR/DPA: since a user that cares
about pending answers should wait for them before initiating
DPR.&BR;
A PPID can be configured with a a gen_sctp sctp_default_send_param
option.</cell>
</row>
<row>
<cell>2.2</cell>
<cell>Securing Diameter Messages</cell>
<cell>PC</cell>
<cell>DTLS is not supported by &man_sctp;. See also

defining the messages of the applications.</cell>
</row>

<cell>As documented, the election assumes knowledge of a peer's
DiameterIdentity when initiating a connection, which diameter
doesn't require. Connections will be accepted if configuration
allows multiple connections per peer to be established or there is
no existing connection. Note that the election process is only
applicable when multiple connections per peer is
disallowed.</cell>
