Modern communication systems are probable to surface new challenges while introducing innovative fronts concerning context consciousness in wireless networks. The main outcome behind this expected technological jump will be a whole novel set of intuiting aptitudes forecasted for Fifth Generation (5G) enabled devices. In line with 5G, Software De ned Networking (SDN) is also rising as an intrinsically novel phenomenon.SDN is an unconventional methodology and key technology in modern communication. SDN maintains favorable novelty about network programmability, where network administration is permitted with extraordinary intellections. SDN architecture has the prospective to allow, simplify or augment security implementations in network through instantly reprogrammable centralized view of the data plane. In the near future, 5G and SDN will ripe mobile communication through the development of state-of-the-art implementations such as a smart city, advanced military security, modern national defense, intelligent tra c, etc.; thereby, these emerging mobile communication concepts invoke various signi cant topics, where security is a paramount implication. Therefore, we initiate our focus from basic architecture of 5G and SDN. Next, we analyze security requirements, solutions and challenges in joint paradigm of 5G and SDN. Further, considering the modern communication technological shift, we discuss future trends and research directions in the joint era of 5G and SDN technologies. IntroductionThe unremitting growth in the capacity and aspects of data apprehended by technological advancements has shaped diversi ed ow of data in either organized or unorganized format such as the rise of social media, Internet of Things (IoTs) for Healthcare [1] and huge multimedia communications. Indeed, the rapid expansion of the Internet industry is considerably dependent on communication system speed, which has emerged as a critical steering factor for the advancement in computer networks [2]. Scienti c advancements are rapidly changing the information technology; thereby computer networks are expanding towards incorporation, dissemination, modi cation and intelligence [3]. The pillar behind this anticipated technological hop will be an entire novel set of aptitudes forecasted for Fifth Generation (5G) communication [4]. 5G is encapsulating all advanced emerging technologies like Arti cial Intelligence (AI) [5]. Within the near future, 5G will reap portable communication organized through the advancement of inventive executions such as smart city, smart grid system, advanced military security etc. So, it is considered fundamental to boost the organized engineering of 5G technology. Likewise, Software De ned Networking (SDN) technology is expanding eminently everywhere globally due to its programmable [6], economical, agile, robust and consolidated networking. 5G is more complex and harder to manage as compared to conventional computer telecommunications and satellite communication systems. SDN is a potential organized design that abridge...

Software Defined Networks (SDNs) are becoming an increasingly important paradigm in modern networking. By making it possible to detach the control plane from network devices and to instruct those devices via a high-level programming language, SDNs yield a number of administration-level improvements, such as better policy-driven network management and easier support for multi-tenancy. However, moving the complexity of network administration to the controllers entails additional challenges, such as scalability, support for different controller network topologies, and efficient maintenance of network state information. In this paper, we consider a distributed and decentralized approach to the SDN paradigm, targeting zero-configuration scalability and transparency through the Zenoh framework. We explore the application of Zenoh as an east/westbound protocol for SDNs and compare its performance against that of a strongly coupled HTTP-based alternative. Our results show that Zenoh's support for distributed queries enables our SDN architecture to effectively scale to hundreds of SDN controllers with zero configuration overhead, while supporting high east/westbound query throughput.
