FlowEngine Software

Intelligent Traffic Distribution Software

Accelerate application development, while improving overall SDN/NFV architecture densities and economics

FlowEngine is a high-performance OpenFlow-compliant data plane software which enables communication service providers to rapidly deliver new time-to-market applications in a scalable, SDN-enabled network, while reducing network complexity and CapEx costs.

We designed FlowEngine software to operate in both data center and telecommunications environments that demand high flexibility, scalability and guaranteed performance. It delivers a high-speed flow classification and intelligent load balancing engine for distributing millions of flows to the required physical or virtual services, improving resource availability and business continuity. The FlowEngine software architecture features a flexible data path that can evolve with changing network needs. It integrates OpenFlow standards to enable simple to complex application use cases without a long cycle of software development.

Radisys FlowEngine - Intelligent Traffic Distribution for SDN and NFV

Network Operators require intelligence in their core network functions so they can manage flows more efficiently through the network. This function is increasingly being deployed using Network Functions Virtualization (NFV). Watch this video and find out why the Radisys TDE-1000 with FlowEngine technology provides a game-changing approach.
