Sandvine, a provider of broadband network offerings for fixed and mobile operators, and Heavy Reading, an independent research organization, this week released a whitepaper entitled “Policy Control & SDN: A Perfect Match?”

The whitepaper addresses potential strategies and opportunities for operators to integrate network policy control into nascent Software-Defined Networks (SDN) architectures.

“Policy controllers and the SDN controllers could be highly synergistic; acting as the brains of the system, the policy controller tells the SDN controller how to route a specific flow, working closely with other elements in the service chain such as DPI, video optimization and firewalls,” said Graham Finnie, chief analyst and whitepaper author, Heavy Reading.

“Policy control in its broad sense, including elements such as subscriber profile repositories, policy enforcement systems, analytics tools and network probes can all help to make SDN controller decisions ‘subscriber-aware’.”

Don Bowman, chief technology officer at Sandvine, said “SDN provides an ideal way to direct data flows in the network, but some technical details will need to be worked out. An operator has to carefully assess the access, distribution and core network paths to ensure that traffic asymmetry and multi-path routing are handled intelligently. Traffic needs to be steered in and out of the network functions cloud with full subscriber, state and resource capacity awareness.”
