## 2 Motivation and Related Work
They acknowledge the complexity of serving a high number of heterogeneous services at the edge or fog because of the variety of requirements in terms of QoS parameters each application exhibits. Nevertheless, they invoke [PERSON]'s SP variant to evaluate candidate paths, limiting the scope and effectiveness of their solution, without incorporating critical QoS parameters like jitter, delay, or throughput. The research presented in [38] focuses on the diverse QoS demands of industrial applications, which makes the provision of suitable resource mappings across industrial 5G-based Time-Sensitive Networks (TSNs) a challenging task. First, they design a QoS-aware greedy algorithm to obtain an initial mapping. To further guarantee the low-latency requirements of higher-priority specialized applications, they develop an integrated QoSconfiguration scheme with delay as the optimization metric. Although their experimental data show that during the VNF mappings the proposed algorithm fulfills the performance standards, they ignore the parallel effect other performance components may have on the VNF mappings, harming the user's Quality of Experience (QoE) of mission-critical user-centric applications. Regardless of using different resource embedding techniques suitable for NG environments, all of the above solutions incorporate a common flawed approach. They apply monothematic evaluations of the available paths, limiting their scope and effectiveness. On the contrary, the research portrayed in this work focuses on a more holistic engagement. The proposed Wii-enabled framework multidimensionally and adaptively describes the available resources and by extension provides successful performance-driven human-centric orchestrations, achieving the innovation for 6G deployment [25]. Moreover, its architecture-independent nature due to the utilization of the PA principles renders this solution capable of seamless implementation and scalable by design. Specifically, already-established characteristics of the routing metrics of routing protocols have been exploited and incorporated into this research [39; 40; 41]. They are proven necessary and sufficient to cause a metric that utilizes the PA formalism to converge seamlessly within an arbitrary network, separate from vendor-specific implementation details [27; 28; 29; 30]. Under this prism, the proposed path evaluation framework, by adhering to the same algebraic characteristics that enable transparent deployment, poses as a generic path resource evaluation mechanism for mission-critical applications, regardless of network topology and other vendor-specific requirements. This technological neutrality allows the advanced refinement of any resource evaluation mechanism. Thus, the benefits of this work can range from successfully upgrading already-established and productive exact and heuristic techniques to ensuring high-performance standards for NGN applications in the CEE continuum. Furthermore, by incorporating already-available and easily calculated metrics, critical services and applications can be facilitated in a simple and efficient manner. To the best of the authors' knowledge, this is the first attempt to comprehensively and multidimensionally address the problem of human-centric performance-driven resource evaluation. By integrating specialized user-defined impact factors with the PA-enabled VNE methodology, the goal of elevating the end-user experience of 6G-compatible mission-critical applications is achieved.
