Artificial intelligence (AI) is expected to play a significant role in meeting critical needs for 6G networks because the majority of intelligent applications are being deployed at the edge [6]. The authors outlined the need for a 6G network for AI applications before providing a thorough overview of AI toward 6G networks. They focused on the demands, trends, and problems of distributed edge intelligence in upcoming 6G networks. Then, 6G networks are used as inspiration for a discussion of a liquid-specific and adaptable software-defined network architecture for AI applications. [PERSON] et al. (2022) [7] examine the most recent security automation research projects in SDN environments. Different classes of security solutions with varying degrees of automation and complexity were discovered and ranked. Four clearly defined qualitative parameters--self-healing, self-adaptation, self-configuration, and self-optimization--are used to gauge the degree of automation. The quantity of processing, storage, and implementation requirements serve as indicators of complexity. The Internet of Things (IoT) of today will become a gigantic IoT of the future as the number of internet-connected gadgets rises [8; 9; 10; 11; 12]. On distributed-controller software-defined networking, network policy updates must be committed in a consistent manner. If this does not happen, the network can encounter unanticipated transient configuration states that affect its performance, security, or even proper operation [13]. By providing a comprehensive view of the network, Software-Defined Networking (SDN) makes it possible to administer networks effectively [14]. Although SDN was not specifically designed to address IoT problems, it can nonetheless give the motivation to address complex problems and aid in effective IoT service orchestration. IoT realization is a difficult problem because of the present IoT paradigm's large data generation, complex infrastructures, security risks, and requirements from the recently developed technologies. Due to its benefits in offering broad access services and the quick development of satellite technology, the space information network has been presented as a solution to address the rising demands of ubiquitous mobile communication [15]. However, the extremely dynamic topology and the limited resource availability of satellites make management and resource use difficult for development. In order to streamline management and boost resource efficiency, some effort has been made to integrate the SDN, also known as the software-defined space information network. [PERSON] et al. (2022) [16] provide a unique lightweight measuring system that operates in the controller in order to lessen the overhead involved in the measurement process and achieve roughly fine-grained measurements. Coarse-grained measurement and interpolation optimization make up the innovative lightweight measurement architecture. [PERSON] et al. (2022) [17] state that virtualization and Software-Defined Networking (SDN) are two promising technologies for affordably addressing the size and versatility needed for IoT. Following a discussion of traditional IoT networks and the necessity of SDN and Network Function Virtualization (NFV), the authors examined SDN and NFV solutions for various IoT implementation strategies. According to [PERSON] and [PERSON] (2019) [10], researchers must consider integrating new technologies rather than making minor changes to the LTE specifications since rising user networking demands in industrial automation, precision agriculture, and augmented reality are driving the development of 5G networks. A rapid and effective response must be made in the present world of smart communication, processing, and operation [18]. According to [PERSON] et al. (2020) [19], SDN enables network managers to more flexibly apply security defense mechanisms to its network-wide visibility, monitoring, and flexible network programmability.
