+ .
+ This package provides the PGW or PDN-GW (Packet Data Network Gateway)
+ element f the EPC, i.e. the gateway between the EPC and the external
+ packet data network, such as the public Internet.  It implements the S5
+ interface towards the S-GW, the SGi interface towards the Internet,
+ and the S7 interface towards the PCRF.

+ NextEPC is a C-language Open Source implementation of the 3GPP Evolved
+ Packet Core, i.e. the core network of an LTE network.
+ .
+ This package contains the PCRF (Policy and Charging Rules Function),
+ which controls the service quality (QoS) of individual connections and
+ how to account/charge related traffic.  It implements the Gx interface
+ towards the PGW using the DIAMETER protocol.

+ NextEPC is a C-language Open Source implementation of the 3GPP Evolved
+ Packet Core, i.e. the core network of an LTE network.
+ .
+ This package provides the HSS (Home Subscriber Server) element of the
+ EPC, i.e. the central database of mobile network subscribers, with
+ their IMSI, MSISDN, cryptographic key materials, service subscription
+ information, etc.  It implements the S6a interface towards the MME
+ using the DIAMETER protocol.

-# This file documents the configuration format for the dict_legacy_xml.fdx freeDiameter extension.
-# In order to load this extension, please refer to main freeDiameter.conf manual.
-
-# This extension allows the use of Diameter dictionary files in XML format,
-# as roughly specified in draft-frascone-xml-dictionary-00.
-# (the actual format is the one from OpenDiameter latest version)
-# Note that this format, although more widely used, is less efficient than the
-# internal freeDiameter format. It is recommended when possible to use the later.
-
-# You may refer to the contrib/dict_legacy/README file for information on where to find such resources.
-
-# This file simply consists in a list of XML dictionary files that must be parsed.
