Abstract

The subject matter described herein includes methods, systems, and computer readable media for providing virtualized Diameter network architecture and for routing traffic to dynamically instantiated Diameter resource instances. A system for providing virtualized Diameter resources and for routing traffic to dynamically instantiated Diameter resource instances includes a cloud virtualizer for virtualizing a hardware pool and for supporting dynamically instantiated Diameter resource instances. The system further includes a cloud orchestrator for monitoring network and hardware events and for instructing the cloud virtualizer to instantiate Diameter resource instances or to reallocate hardware from the hardware pool among instantiated Diameter resource instances in response to the network or hardware conditions. The system further includes a cloud flow manager for dynamically configuring at least one network element for routing traffic to the dynamically instantiated Diameter resource instances or the allocated hardware.
