Citrix Secure Private Access White Paper. WebSDN represents a substantial step forward from traditional networking, in that it enables the following: Increased control with greater speed and flexibility: Instead of manually programming multiple vendor-specific hardware devices, developers can control the flow of traffic over a network simply by programming an open standard software-based controller. Join the nonprofit community for students transitioning from other fields to doctorate-level medical training. The control of all the data plane devices are done via SDN Controller. Decoupling the forwarding plane and control plane of network devices, SDN uses the controller for network device management, network service orchestration, and service traffic scheduling, which features low costs, centralized management, and flexible scheduling. The SDN abstracts physical network resources (such as switches and routers) and transfers decision making to the virtual network control plane. There are fourunique and defining features of SDN: SDN relies on APIs to create a centralized management plane that lets administrators and managers decide and program network behavior. The control plane is the brain of the operation, managing network services and deciding how and where packets should move throughout the network. Join 1000s of nontraditional pre-health students, just like you. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the.
