I'm trying to understand the fundamental structure of Software-Defined Networking (SDN). Specifically, I want to know if SDN is designed to be centralized, where all the control and intelligence are in one place, or decentralized, where these functions are distributed across the network.

To address these issues, Distributed SDN (DSDN) has been proposed as a solution. DSDN aims to eliminate the single point of failure by distributing the control plane across multiple nodes.

Furthermore, DSDN addresses the security concerns associated with centralized SDN controllers. By distributing the control plane, DSDN creates a more resilient and secure network that is less vulnerable to attacks.

SDN's centralized nature introduces vulnerabilities that need addressing. One significant concern is its susceptibility to a single point of failure (SPoF). This means that if the central controller fails, the entire network can be disrupted.

In addition to SPoF, scalability is another issue that arises with centralized SDN. As the network grows, the central controller may become overwhelmed, leading to performance bottlenecks and inefficiencies.
