OpenBlox Diameter Stack – Technology

Building a Diameter Connection You Trust

OpenBlox Diameter Technology

The OpenBlox Diameter stack is the market's only pure Java Diameter implementation and is released also as pure C++. The OpenBlox Diameter stack is also available with a full J2EE Java Diameter extension. All OpenBlox versions have the same API and share the same look and feel.

• OpenBlox Diameter Stack - Java
  The OpenBlox Diameter Stack - Java is a full implementation of the Internet Engineering Task Force (IETF) Diameter (RFC 3588) and is comprised of 3GPP, 3GPP2 and ETSI Diameter interfaces and applications.
• OpenBlox Diameter Stack – J2EE
  The J2EE version is implemented as standard JCA 1.5 compliant resource adapter and extends the OpenBlox capabilities to J2EE and SOA environments. Thus, any J2EE Application Server with OpenBlox J2EE Diameter becomes a legitimate node in the AAA and control domain of a telecom operator.
• OpenBlox Diameter Stack – C++
  OpenBlox C++ Diameter Stack C++ is a full implementation of the Internet Engineering Task Force (IETF) Diameter (RFC 3588) and is comprised of 3GPP, 3GPP2 and ETSI Diameter interfaces and applications.
