Scaling and using Radiator in the cloud just became even easier

Radiator has long supported scaling with features such as server farm (FarmSize) and multiple load balancing algorithms. In the latest Radiator patches we introduce the first features in the series of new improvements aimed to make Radiator a perfect RADIUS/Diameter AAA component from private and telco clouds to public clouds such as Amazon.

As operators gradually move away from physical servers and appliances to architectures like telco clouds, network functions virtualisation (NFV) and software defined networking (SDN), the need for software components capable of scaling and communicating between each other increases. A modern AAA (authentication, authorisation, accounting) software component must have features for communication, organising cooperation (orchestration) and dynamic load balancing and that is where we started.

The current Radiator patches now include Gossip framework with an implementation built on top of Redis. Proxying and load balancing were enhanced to use Gossip for sharing information about next hop proxy reachability and unreachability. This provides fast detection and recovery from proxy failures for cooperating Radiator instances across several, even separate, servers. In addition to sharing information about network events, Gossip based duplicate cache is now available for server farm instances. This is, however, only the beginning. Moving towards Radiator 5.0, we are adding more features supporting new and future operator cloud functionalities. As always, patches will include these coming features first.

We fully recognise that we cannot do and figure out everything by ourselves and welcome your feedback. This helps us to continue developing Radiator to the component you want to use when building your services and products.
