Real Life Use Cases for Diameter Control Plane Scaling Next generation applications and smart phone usage consume t r e m e n d o u s w i r e l e s s d a t a c a p a c i t y. S c a l i n g t h e c o n t r o l p l a n e to load balance Diameter control plane transactions is imperative to increase revenue and ensure customer satisfaction. The Traffix Diameter Load Balancer is a native Diameter network entity. It was designed to support message-based load balancing in advanced telecom networks, allowing for contextual load balancing on the Diameter control plane and resilience to failovers and traffic spikes. An important part of any control plane architecture, this technology supports the introduction of scalable and efficient Diameter-based Next Generation Networks (NGN). Load Balancing Diameter in a P repaid Intensive Environment What If…. A large percentage of your customer base is prepaid and they all consume increasingly sophisticated applications on their Smartphones? The Problem: With dozens of GGSNs and OCSs load balancing control plane traffic is a n e c e s s i t y. Each and every prepaid data transaction needs to be authorized between a Diameter client (e.g. GGSN) and a Diameter server (e.g. Online Charging System (OCS)). Data traffic is only allowed after the user's account balance is verified – a great challenge given the exponential increase in cellular data traffic and sheer transaction volume. To make things worse, OCS response time is slower than GGSN requests; as a result, load balancing is required between many OCS Diameter servers and less corresponding GGSN Diameter clients. Outages mean "no business". No real time transaction authorization. No revenue, less prepaid service availability and less customer satisfaction. Scaling with Traffix Diameter Load Balancer: With dozens of GGSNs and OCSs load balancing control plane traffic is a necessity. The load balancing algorithms in Traffix Diameter Load Balancer direct each request to the right OCS, using Diameter level contextual load balancing methods, en a bl i n g re a l t i me authorization of prepaid data traffic, scaling Diameter traffic across the different Diameter servers and clients and ensuring availability, service revenue and customer satisfaction.
