What are the basic work process steps of SDN?

In the context of Software-Defined Networking (SDN), the foundational work processes are pivotal for managing and orchestrating resources in a network environment. The basic step of collecting network element (NE) resource information is crucial as it involves gathering data about the various devices and components within the network. This step allows network administrators to understand what resources are available, their current status, and how they can be utilized or configured effectively.

Collecting this resource information serves as a baseline for further actions in the SDN architecture. It supports efficient resource allocation and ensures that the network can respond dynamically to changes in demand or operational conditions. This foundational data gathering is essential for tasks such as network planning, optimization, and troubleshooting, which are all integral to the SDN workflow.

The other processes listed, while relevant to network management, are typically subsequent steps and often depend on the accurate and comprehensive collection of resource information. Understanding the available resources is what enables the generation of efficient routing, the analysis of traffic patterns, and the mapping of network topology. Therefore, the collection of NE resource information is a critical first step in the overall SDN operational workflow.
