1 F5 Traffix Use Cases for SDC Diameter Router

2 Traffix Signaling Delivery Controller Diameter Router: Better Control of Your Network Real life use cases to bring simplicity to the Diameter Control Plane The number of network entities is constantly increasing as networks become more complex. Each entity represents a Diameter node and given the growing quantity of signaling with the surge of mobile data combined with new policy and charging models, service providers are struggling to manage their control plane and Diameter signaling. The Traffix SDC Diameter Router is one of three solutions in the Traffix Signaling Delivery Controller (SDC), a native Diameter network entity. The Traffix Diameter Router is a full spec compliant Diameter agent, following the IETF Diameter RFP s, 3GPP Diameter Routing Agent (DRA) specifications and GSMA Diameter Edge Agent (DEA) guidelines. An important part of any control plane architecture, Diameter routing technology supports the introduction of scalable and efficient Diameter-based services and networks. Routing Diameter for end to end policy control The Problem Operators want to enable premium LTE customers the same quality experience while traveling as they enjoy while at home. Home networks PCRFs (policy charging & rules function) need to communicate with visited network PCRF based on any given external service providers and from any potential vendor. Interoperability issues between the home PCRF vendor and the visited PCRF vendor are expected and roaming of incoming and outgoing messages, with stickiness and redundancy to maintain the same route for incoming/outgoing messages, handle long term open sessions and of course, enable redundancy and scalability.

3 Simplicity with the Traffix SDC Diameter Router: With the growing number of PCRFs communicating in your home and visited domain, with almost any-toany cross network PCRF connectivity, a Diameter Router is not an option any more, but a central architecture node from day one. Traffix SDC Diameter Router normalizes visited PCRF Diameter messages to ensure they follow your home network Diameter signaling format. The Traffix SDC Diameter Router supports hundreds of thousands of concurrent Diameter sessions to route across different networks and domains, and of course, to satisfy any service provider redundancy and backup requirements. Cross PCRF/PCEF Diameter Routing The Problem: You wanted each of your network's PCRF to communicate with any PCEF, maintaining the state for each session supporting long sessions and customers moving across your network. With the rapid adoption of policy and charging control service providers find themselves with dozens of PCRF and PCEF functionalities spread across different sites that introduce a never seen before quantity of signaling. These new usage patterns introducing multi-attachment technologies and services that are always on, always connected, challenge operators to maintain a high quality of service for subscribers. Traffix SDC Diameter Router solves these challenges in three ways: It maintains configurable, real time and policy based routing across PCRF/PCEF domains, enabling service providers to segment and manage the network and define and control the backup and redundancy procedures. It maintains session state across PCRF s and sites to enable PCRF/PCEF geo redundancy It reduces the amount of Diameter signaling created and sent across the network by using advanced mechanisms.
