SDN/NFV Implementation

Software-Defined Networking (SDN) on OpenStack is the hottest trend that helps service providers transform their networks. NFV allows service providers transform their network paradigm from fixed, closed and vendor-specific infrastructure to an open, scalable and service-agile environment. SDN/NFV 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 based on Virtual Network Functions.

Bell.One works to deliver on the promise of OpenStack powered clouds with SDN/NFV solutions.

Key Features

The picture 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.

Benefits

  • Removes the complexity of integrating networking technologies in OpenStack clouds
  • Increases operational effectiveness
  • Significantly reduces operational expenses
  • Reduces capital costs by enabling service providers and IT administrators to easily embrace open SDN and OpenStack technologies in their environments
