The booming growth in multimedia content today can mean millions of subscribers creating hundreds of millions of data sessions – all within a single service provider network. Operators are scrambling to find effective ways to manage, optimize, and monetize data plane services, and many are looking to software-defined networking (SDN) and network functions virtualization (NFV) to help provide data plane services with high throughput and scalability.
While SDN offers flexible control of the network to deliver opex savings, NFV offers the ability to pool resources and simplify the network infrastructure for both capex and opex gains. A new solution brief from Radisys examines how the company’s FlowEngine Intelligent Traffic Distribution System helps operators make the transition to an SDN or NFV environment by delivering intelligent traffic distribution in a software-centric network.
Network traffic distribution today typically requires a complex integration of discrete load balancers, edge routers, and data center switches. As service providers virtualize more of their data plane applications, they find themselves having to choose between suboptimal fixed-packet processing rules, or incurring higher capex and opex costs to deploy load balancing products that can’t handle high data plane traffic volumes.
The solution brief argues that providers need service-aware traffic management where SDN capabilities orchestrate data traffic and NFV resources process it. FlowEngine uses service function chaining under open SDN policy control to classify millions of data flows, then distribute the flows to thousands of virtualized network functions (VNFs) or physical network functions (PNFs). Specifically designed for the challenges of large NFV deployments, FlowEngine integrates key functions from existing switching, router, and load balancer equipment to deliver high-performance Layer 2-4 networking capabilities.
The brief explains how FlowEngine enables providers to scale efficiently while offering increased service agility, and it offers specific use-case examples for:
- Intelligent network traffic distribution
- Service function chaining
- Packet-filter and capture (network tap)
