This needs to be performed dynamically in large networks. SDN facilitates the separation, abstraction, and sharing of network resources, which aids in the virtualized network infrastructure in 5G [25]. NFV is a noteworthy innovation that has profoundly altered networking and service provisioning. While some businesses assert that 5G solutions are already available, there are legitimate worries that we may only see a few SDN point solutions rather than a fully virtualized, SDN-enabled 5G mobile network, given the enormous effort of softwarizing mobile cellular networks [26]. The authors in [27] provided an in-depth analysis and current solutions for 5G network slicing with SDN and NFV. Following a presentation of the 5G service quality and commercial criteria, the authors described the 5G network softwarization and slicing paradigms, outlining key ideas, their background, and many use cases. The management and orchestration of network slices in a single domain are covered, and then a thorough analysis of management and orchestration techniques in 5G network slicing over several domains. In comparison to current 4G technology, 5G infrastructures are anticipated to offer anywhere network access with notable network improved efficiency, including 1000 times more available bandwidth, 10-100 times higher data rate increases, upwards of 90% effi \begin{table}

The author in [28] analyzes and contrasts three SDN-based multi-hop routing methods. An SDN-based BS in the routing framework controls multi-hop connectivity between mobile nodes that are within its coverage region. The architecture makes use of two different frequency bands: licensed frequency for cellular and unlicensed frequency for D2D communication. In order to govern data forwarding, the controller uses both proactive and reactive methods. The authors in [29] developed an SDN-enabled network model that supports the FOG networking paradigm in 5G IoT scenarios in order to assess the viability of the Mininet network emulator as a component of the 5G simulation environment. Hence, it is evident from the linked literature that there has never been a framework for 5G-6G routing information security in SDN utilizing blockchain. Therefore, this work presents a security architecture that combines blockchain technology with Software-Defined Networking in 5G-6G.
