As Diameter signaling messaging grows, service providers need a multi-functional Diameter platform. BIG-IP Diameter Traffic Management enables service providers to manage network complexity with context-aware routing, engage in secure roaming, and successfully integrate all Diameter and legacy elements.
BIG-IP Diameter Overload Control gives mobile operators the scalability, flexibility and performance needed to mitigate the most aggressive, volumetric DDoS attacks and to provide overload protection. It can use BIG-IP Diameter Load Balancing capabilities—easily addressable via one IP address—or define what should happen when more traffic is offered than the destination can handle.
To ensure that charging messages with specific content or profile get to the right Online Charging System (OCS), F5 BIG-IP Diameter Director has preconfigured/onboard rules regarding how to select the right OCS, and will query an external database about the subscriber, then routes to correct OCS based on parameters received from the database.
Service providers need to plan out their signaling migration path from 4G to 5G. F5 is an industry leader in offering robust 4G signaling solutions for service providers with the BIG-IP load balancer, Diameter Routing Agent (DRA), and a Diameter Edge Agent (DEA). Transitioning to 5G is made easy by providing an interworking path between 4G and 5G signaling.
Diameter is a signaling protocol that has been defined by the Internet Engineering Task Force (IETF) as a base protocol “intended to provide an Authentication, Authorization, and Accounting (AAA) framework for applications such as network access or IP mobility in both local and roaming situations.”
