DATATRONICS offers a Diameter Signaling Controller/Router (DSC/DSR) which help to mitigate the signaling storms and congestion. The DSC can be deployed as Diameter Routing Agent (DRA) for routing, traffic management and load balancing, as a Diameter Edge Agent (DEA) for connection to IPX and other operators or as Diameter Interworking Function (IWF) LTE/IMS with legacy 2G/3G.

There are many network elements that need to interconnect using Diameter in the LTE and IMS networks as well as interconnection to legacy networks. In a  research report(1) GSMA  has estimated that 352 mobile operators have launched 4G-LTE networks across 124 countries as of the end of January 2015, that this number will double by 2020, and over 2.5 billion 4G-LTE connections (excluding M2M) will exist by 2020. According to a report from Oracle Communications(2) with LTE penetration on the rise, global Diameter traffic will increase dramatically over five years, from 30 million MPS in 2014 to 395 million MPS by 2019.

So, the need to manage Diameter signaling has become important more than ever and the CSP need to create a secure signaling architecture that reduces the cost and complexity of the core network and enables elastic growth, interoperability and rapid introduction of new services. The DSR also enhances network visibility by providing a centralized monitoring point in the signaling network.

DATATRONICS offers a DSR solution that centralizes routing, traffic management and load balancing. DSR also provides topology hiding,  HSS/PCRF/OCS Address Resolution, Policy and Charging Binding and multivendor interoperability.
