While data traffic continues to grow at an unprecedented rate, the emergence of Long Term Evolution (LTE) networks is causing a fundamental shift in the core network from SS7-based signaling to Diameter signaling. This has given rise to a new class of products referred to as Diameter Signaling Controllers (DSCs) that address the growth and expected congestion in signaling traffic by efficiently routing signaling information. Diameter Agent - While data traffic continues to grow at an unprecedented rate, the emergence of Long Term Evolution (LTE) networks is causing a fundamental shift in the core network from SS7-based signaling to Diameter signaling. This has given rise to a new class of products referred to as Diameter Signaling Controllers (DSCs) that address the growth and expected congestion in signaling traffic by efficiently routing signaling information. With the growth in the number of LTE devices, the increased number of interfaces in the EPC and the migration of signaling from SS7 to Diameter, the volume of Diameter messages in the EPC has exploded. This explosion illustrates the need for a carrier-grade infrastructure to support scalability and reliability for Diameter in the EPC. For SS7 the Signaling Transfer Point (STP) was used to facilitate a carrier-grade infrastructure. For Diameter the Diameter Signaling Controller (DSC) is used for providing the same carrier-grade infrastructure in the EPC. Diameter Routing - Diametriq, an innovator in Diameter signaling control technologies, offers an exceptional suite of DSC solutions, the Diameter Routing Engine™ (DRE). Diametriq’s application enabled Diameter Routing Engine™(DRE) includes a Diameter Routing Agent (DRA), Diameter Edge Agent (DEA), a Subscription Locator Function (SLF) and a Diameter Interworking Function (IWF). These functions can be configured to meet your specific network requirements as well as serve as a host for critical applications that utilize the information contained in Diameter messages.
