Against the massive growth of data services, higher levels of fixed-mobile convergence, and increasing competition from Over-The-Top (OTT) competitors, scalable and cost-efficient networks are a must. Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) on OpenStack are the hottest trends that help service providers transform their networks. These technologies promise a number of benefits, including reductions in both capital and operating costs, fast time-to-market delivery of new services, and improving ROI. Regardless of what kind of network you operate or what kinds of services you offer, NFV and SDN provide opportunities to improve the economics of your network while at the same time accelerating your ability to create, deploy, and manage new service capabilities.

SDN & OpenStack

SDN is a new approach to managing networks that shifts network management from hardware to software. SDN separates the control plane and data plane, allowing administrators to configure networks of switches and routers easily from a central control panel and adjust network-wide traffic on the fly to meet changing business needs. SDN significantly reduces operational expenses by eliminating the need to manually configure hardware. SDN also reduces capital costs, by increasing traffic utilization of routers and other network resources.

software defined networking

The picture above shows the basic software-defined networking architecture. The data plane consists of servers, switches and other network resources forming the system that forwards traffic to the selected destination. Other network elements include firewalls and network interface cards (NICs) that are plugged into a server or network appliance. The controllers make decisions about traffic destination and communicate with the network appliances through a standard interface such as OpenFlow. In large networks, the controllers are managed through an orchestrator using standard interfaces such as Open Stack.


NFV allows service providers transform their network paradigm from fixed, closed and vendor-specific infrastructure to an open, scalable and service-agile environment.

network functions virtualization

A software-driven network strategy allows operators to decouple network functions, such as caching from proprietary hardware appliances, and run them as virtualized software applications in a cloud infrastructure, accelerating service provisioning.
