Diameter Signaling Controller (DSC-DRA-DEA-IWF)

The BroadForward DSC is the Next Generation routing and interworking solution for 3G, 4G/LTE, 5G, IMS, Fixed and Wi-Fi networks. It is a unique single-design software solution for DRA, DEA and multi-protocol interworking. The service orchestration GUI allows users to freely combine protocols with on-board functions to setup advanced service scenarios, without the need for scripting or development.

Description

BFX, the Next Generation Diameter Signaling Controller (DSC)

The BFX Interface Gateway is the Next Generation routing and interworking solution for 3G, 4G/LTE, 5G, IMS, Fixed and Wi-Fi networks. It is a unique single-design software solution for DRA, DEA and interworking. The service orchestration GUI allows users to freely combine protocols with on-board functions to setup advanced service scenarios, without the need for scripting or development.

Functions include routing, any-to-any interworking, mediation, protocol conversion, load balancing and advanced service logic for a wide range of protocols, including Diameter, ENUM, RADIUS, HTTP, LDAP, SS7 etc. The BroadForward DSC offers everything that is needed for advanced routing and interworking in a single software solution. This makes the BroadForward DSC the smartest choice for operators, vendors and integrators to enable advanced use cases across networks, technologies and systems.

Diameter routing and interworking across technologies and domains

The BroadForward DSC offers users a flexible and integrated set of routing and service creation capabilities that work across 3GPP based networks (2G, 3G, LTE, 5G, IMS), non-3GPP networks (Wi-Fi, Cable, DSL, FTTH, Fixed) and IT domains, supporting protocols such as Diameter, SIP, MAP, INAP, CAP (CAMEL), RADIUS, HTTP, XML, REST, JSON, SOAP, ENUM, TCP/TLS, LDAP, UDP, SCTP/TLS to enable signalling scenarios without the need for R&D or scripting.

As a Next Generation DSC, it supports all relevant functions for Diameter routing and interworking, including:

  • Diameter Routing Agent and Edge Agent for any Diameter application, including Gx, Gy, Gz, Rx, Ro, Sy, Sh, S6a, S6b, S6d, S9, S13, SWm, SWx, Cx, Dx, Wx, Diameter SIP Application and SCAPv1/v2
  • Single solution for any-to-any protocol interworking and routing, not just Diameter
  • Works across Diameter, ENUM, RADIUS, SS7 and IT protocols
  • Intelligent routing, ability to route Diameter messages based on various Diameter parameters or combinations of parameters
  • Stateless and stateful load balancing/sharing
  • PCRF binding for VoLTE and VoWi-Fi
  • Admission / Access control, message screening
  • Congestion control, ingress and egress throttling, overload protection, SLA enforcement
  • AVP level mediation and manipulation
  • Network topology hiding
  • Subscriber Lookup Function (SLF), routing based on external data sources (e.g. LDAP, HTTP)
  • Roaming steering
  • Interworking with SS7/MAP, RADIUS and various IT protocols (XML, SOAP, LDAP etc.)
  • Hardware-agnostic solution, supporting NFV and OpenStack

Hardware-agnostic solution, supporting NFV

The BroadForward DSC runs on any off-the-shelf hardware or in a virtualized environment and is Integrated with OpenStack for orchestration and (auto)scaling. All leading virtualization technologies available for Linux are supported, including VMware, KVM and Xen. It does not rely on specialist hardware or proprietary operating systems. BroadForward supports operators and vendors to migrate from proprietary appliance based systems to a standard hardware and cloud based infrastructure.

The BroadForward DSC is an extremely flexible, high performance interface gateway that can run standalone or seamlessly embedded in the majority of new and existing systems to support any network or IT interface with minimal implementation effort. It can simultaneously handle multiple connections on different interfaces in the operator’s network, for both Diameter and non-Diameter interfaces. Running the BroadForward DSC as a virtualized network function on standard hardware will help operators and vendors to get costs down and be more flexible in order to introduce new services much faster.

Benefits

The BroadForward DSC offers major differentiators compared to traditional Diameter Signaling Controller products:

  • Unique combination of DRA, DEA and IWF on a single platform (integrated solution)
  • Software based, supports use of standard hardware, virtualization and cloud deployment
  • Single solution for any-to-any protocol interworking and routing, not just Diameter
  • Works across Diameter, RADIUS, SS7 and IT protocols
  • State-of-the-art GUI, no need for scripting or development. GUI-based configuration and management for connections, message flows, mediation, service logic and dashboards
  • Extensive mediation and interworking capabilities, no need for scripting or development, fastest time to solve Diameter incompatibilities and fastest time to market for service innovation
  • Most complete MAP-Diameter interworking function (on-board)
  • Supports integration with subscriber databases and IT systems
  • Structural reduction of integration efforts, hardware costs and vendor lock-in effects
  • BroadForward offers the DSC either standalone or together with the Signaling Transfer Point (STP)
