SVI-DSC Deployment Scenarios

Diameter Routing Agent - DRA

The Diameter Routing Agent is the central routing point in any Diameter network providing flexible routing and message manipulation to insure inter-op between multiple devices and device vendors. At the same time it prevents overload and congestion of diameter traffic through sophisticated load balancing and routing algorithms whilst delivering graceful scaling to match network demand.

Interworking Function – IWF

The Inter-working Function (IWF) provides a vital bridge between legacy networks and Diameter based 4G LTE networks. Supporting 3G SS7 MAP and CAMEL inter-op with 4G Diameter insures service providers can rapidly provide roaming for their subscribers without having to upgrade legacy equipment. Offload to incumbent WiFI networks can also be supported through Diameter to Radius inter-op.

Diameter Edge Agent – DEA

At the edge of the Diameter network sits the Diameter Edge Agent. Its primary function is to provide network security with secure exchange of authentication, authorisation and subscriber policy. Out of the box it provides topology hiding, DOS and DDOS protection whilst also delivering load balancing and congestion control functionality.
