SDNprotokollat

SDNprotokollat refers to the communication protocols used in Software-Defined Networking (SDN). SDN decouples the network control plane from the data plane, allowing for centralized control and programmability of network devices. This separation is enabled by standardized protocols that facilitate communication between the SDN controller and the network devices (switches and routers).

The most prominent protocol in this category is OpenFlow. OpenFlow acts as an interface between the SDN controller and the forwarding plane of network devices. It allows the controller to define how packets should be forwarded by instructing the switches to install, modify, or delete flow entries in their flow tables. These flow entries specify matching rules (based on packet headers) and corresponding actions (e.g., forward, drop, modify).

Other protocols and standards are also relevant to SDNprotokollat, though they may serve different purposes or operate at different layers. For instance, NETCONF and YANG are often used for network configuration and management, providing a programmatic way to configure devices that can be integrated with SDN controllers. While not directly controlling packet forwarding like OpenFlow, they are crucial for the overall management and orchestration of an SDN environment. The specific set of protocols used in an SDN deployment can vary depending on the vendor, the architecture, and the intended functionality. The goal of these protocols is to enable intelligent, dynamic, and automated network management.
