• Software-Defined Networking (SDN)

    • Software-Defined Networking (SDN) is a programmatic approach to networking with centrally managed network intelligence. SDN reduces the risk and administrator overhead while improving the overall network efficiency. With SDN, the function of traffic control is separated from the network hardware – this allows the network to add new apps and capabilities without consuming much time and money.

    • Who uses Software-Defined Networking (SDN) and why?

      Enterprise IT organizations use SDN to reduce their dependence on expensive hardware, streamline their physical infrastructure and avoid vendor lock-in. Powered by SDN, these organizations will have massive scalability and flexible deployment options. The hardware layer is decoupled from the software, resulting in more agility, lesser network downtime and optimal network productivity.

      How does the Software-Defined Networking (SDN) work?

      SDN separates the network control plane from the forwarding plane and lowers the need for manual configuration because the traffic is managed by a centralized controller (software). The network resources can be dynamically optimized and secured by implementing policies to the network traffic. The policy based automation aspect of SDN also allows the network to expand into large number of nodes.

      Benefits of Software-Defined Networking (SDN)

      Reduces cost – Lowers CAPEX cost by minimizing the need for hardware devices such as routers & switches. Lowers OPEX costs due to massive improvement in network management.

      Improves network productivity – Ensures effective load balancing, better content delivery and improves the network uptime.

      Better security – Secures the mission critical workloads by implementing dynamic security policies.
