“…Finally, as discussed in [21] a number of research challenges are still open, especially taking into account the availability status of the network (e.g., switch/link capacity usage) that might affect the actual QoS performance (e.g., throughput) experienced by data while traversing service chain paths. For this reason, as we do in this work, recently a number of research works tackled different aspects of the service chain orchestration as an effective solution to dynamically address service requirements from applications and users [25].…”

“…Therefore, dynamically assigning resources to the users while protecting other slices offer significant performance improvement. On the other hand, an extensible framework for elastic service function chaining is proposed in [33]. Other than elasticity, end-toend optimization deals with the efficient use of all resources efficiently without compromising QoS.…”

Fifth-generation (5G) and beyond networks are envisioned to provide multi-services with diverse specifications. Network slicing is identified as a key enabling technology to enable 5G networks with multi-services. Network slicing allows a transition from a network-as-an-infrastructure setup to a networkas-a-service to enable numerous 5G smart services with diverse requirements. Although several surveys and tutorials have discussed network slicing in detail, there is no comprehensive study discussing the taxonomy and requirements of network slicing. In this paper, we present and investigate key recent advances of network slicing towards enabling several Internet of Things (IoT) smart applications. A taxonomy is devised for network slicing using different parameters: key design principles, enablers, slicing resources levels, service function chaining schemes, physical infrastructures, and security. Furthermore, we discuss key requirements for network slicing to enable smart services. Finally, we present several open research challenges along with possible guidelines for network slicing.

“…Based on a greedy algorithm, a heuristic algorithm was proposed to improve the success rate and reduce the embedding cost. The authors of [13] proposed a new SFC deployment framework X-FORCE in 5G network to deploy SFC and manage the SFC life cycle. The framework improved network performance and saved network resources.…”

Network function virtualization (NFV) in 6G can use standard virtualization techniques to enable network functions via software. Resource scheduling is one of the key research areas of NFV in 6G and is mainly used to deploy service function chains (SFCs) in substrate networks. However, determining how to utilize network resources efficiently has always been a difficult problem in SFC deployment. This paper focuses on how to efficiently provision online SFC requests in NFV with 6G. We first establish a mathematical model for the problem of online SFC provisioning. Then, we propose an efficient online service function chain deployment (OSFCD) algorithm that selects the path to deploy that is close to the SFC length. Finally, we compare our proposed algorithm with three other existing algorithms by simulation experiments. The experimental results show that the OSFCD algorithm optimizes multiple performance indicators of online SFC deployment.
