A. B. C. D.C.
With software-defined networking (SDN), the filtering of network traffic is separated from the forwarding of network traffic so that it can be independently administered.
Software-defined networking (SDN) is an approach to network management that separates the control and data planes of a network architecture. The control plane, which makes decisions about how traffic should be forwarded, is abstracted from the data plane, which actually forwards the traffic.
With SDN, a centralized controller manages the network and communicates with individual switches and routers to determine the optimal path for traffic. This means that the traditional methods of network management, such as manual configuration of individual devices, can be replaced with automated policies that can be updated in real time.
In terms of what aspect of networking is abstracted from the forwarding of traffic with SDN, the answer is A. Routing. SDN allows for the centralization of routing decisions, meaning that routing can be abstracted from the forwarding of traffic.
Session, filtering, and firewalling are all still important aspects of network management, but they are not directly abstracted by SDN in the same way that routing is.
Overall, SDN offers numerous benefits for network management, including increased flexibility, scalability, and security. By abstracting routing from the forwarding of traffic, SDN can help to streamline network management and make it easier to adapt to changing business needs.
