The BroadForward SCP in your Network

The BroadForward Service Communication Proxy (SCP) provides the network with a intelligent control point for all HTTP/2 SBI traffic inside the 5G Standalone core. Once deployed in the network, it continuously orchestrates how 5G Network Functions communicate, by replacing rigid point‑to‑point connections with a centrally managed service mesh architecture. The SCP enforces dynamic routing policies, balances NF traffic loads, strengthens perimeter harmonization and inter‑NF security, and provides deep operational visibility – allowing operators to centrally govern, monitor, and optimize service‑based NF interactions across the entire 5G core. The BroadForward SCP is built for carrier grade performance, delivering stable low latency routing and high volume transaction processing on modern multi core deployments, trusted by operators with demanding 5G service mesh environments.

Streamlining 5G Signaling: Centralized Control for Service-Based Architectures

Simplifies SBA operations by centralizing routing, discovery, and traffic control across all 5G core functions.

Every BroadForward product runs on the BFX USC - one engine, one operational model. Adding and operating new 2G–5G signaling functions is straightforward because all BroadForward products use the same GUI, provisioning model, workflows, and operational environment - one interface for all signaling.

Features a 100% graphical interface (CLI is also supported) for configuring routing, message harmonization, and service logic, empowering operators to adapt policies instantly without custom coding or vendor change requests.

Includes native 4G-to-5G interworking functions (IWF) to connect HTTP/2 service-based 5G core functions directly with legacy Diameter nodes (e.g., 4G PCRF, OCS, and EIR) for phased network function implementations and network migrations.

Supported Standards & Core Features

3GPP Indirect Communication Fully compliant with 3GPP TS 23.501 Model C (direct NRF discovery, SCP routing) and Model D (delegated NRF discovery and selection to SCP).
HTTP/2 & RESTful SBA Protocol Support Handles 5G Service-Based Architecture (SBA) control plane signaling over HTTP/2 with full header parsing, parameter routing, and JSON body inspection and mediation.
3GPP NRF Integration & Registration Automatic registration with the Network Repository Function (NRF), supporting dynamic service discovery, NF profile caching, and health status notifications.
One Engine, Any Protocol All BroadForward products run on the BFX Unified Signaling Core (USC), providing one engine and one operational model for all 2G–5G signaling functions. The same GUI and workflows apply across all products, delivering a single interface for all signaling.
Script-Free GUI Signaling Orchestration Provides a 100% graphical environment to build custom routing logic, message harmonization, and mediation rules without writing custom code or paying vendor CR fees.
Efficient & Cloud‑Agnostic Architecture Designed for low resource consumption and maximum deployment flexibility across bare metal, virtualized platforms, containers, or hybrid cloud environments.

Extended Features

Support for BSF For deployments requiring PCF binding, the BroadForward SCP can be combined with the BroadForward Binding Support Function (BSF) to enable accurate PCF selection and optimized routing of policy‑related signaling.
3GPP Security & OAuth2 Authorization Enforces transport-layer security using TLS 1.3/1.2 and validates OAuth2 access tokens for secure inter-NF authorization.
Advanced Traffic & Overload Management Complies with 3GPP traffic steering and congestion control specifications using ingress/egress rate limiting, request prioritization, and dynamic load balancing across NF sets.
gRPC Interface for Traffic Monitoring Provides a dedicated channel that forwards decrypted copies of SCP signaling traffic to the operator's network monitoring and analysis systems.
3GPP 4G–5G Interworking (IWF) Provides interworking between 5G SA HTTP/2‑based core functions and legacy 4G Diameter‑based nodes (such as PCRF, OCS, and EIR), enabling phased migrations and hybrid architectures (Optional).

Deployment

Freedom of Environment: Deploying Where it Makes Sense

With the BFX Unified Signaling Core (USC) at its core, operators are not tied to a specific hardware vendor, appliance cycle, or hyperscaler. The BroadForward SCP can be deployed or migrated across virtual machines, containers, or bare metal, using the same configuration, without re engineering. Because BroadForward SCP separates the underlying execution platform from its routing logic, configuration, and security profiles, moving environments requires no re-engineering. All service logic, HTTP/2 message routing rules, parameters, and connection configurations built in the GUI can be exported as clean, platform-independent configuration files.
