Diameter Routing Agent (DRA)

Diameter Routing Agent (DRA)

A Diameter Routing Agent (DRA) is a functional element in a 3G or 4G (such as LTE) network which provides real-time routing capabilities to ensure that messages are routed among the correct elements in a network. The DRA was introduced by the 3GPP to address the increased Diameter signaling traffic and growing complexity of 4G LTE networks.

Networks with complex architectures and multiple Diameter nodes require an advanced Diameter contextual routing engine. Choosing a DRA that' s capable of advanced contextual routing is essential to managing network complexity and capitalizing on all that 4G LTE has to offer.

Key Benefits:

• Low CAPEX & OPEX
  Single integrated platform for DRA and DEA
• Interoperability
  Allow to work different Diameter products and brands
• High Scalability
  NFV compliant allowing delivery on a range of cloud
• Support multiple network
  Diameter, RADIUS, SS7 and various IT protocols
• Flexibility required for Roaming
  DEA for connection to IPX and other operators
• Future-proof, extendable approach
  New interfaces and features can be supported by the same solution.

Telcovas DRA Enable interoperability, elastic growth and congestion control

• Telcovas offers an integrated DRA software solution dedicated to run on any hardware or cloud infrastructure for Network Function Virtualization (NFV) to cope with such new challenge of engineering Diameter traffic deeply into the Evolved Packet Core (EPC) Network. Our solution is the enabler of fluid Diameter traffic between the key components of the IMS based network architecture namely HSS, AAA Server, PCRF, OCS on one side and PCEF, MME, PGW and SGSN on the other side thanks to its combination of DRA and Diameter Edge Agent (DEA) .
• Telcovas DRA empowers operators and vendors to independently resolve signaling issues and enable advanced service scenarios, across vendor and access technologies.
