“…For comparison purposes, we contrast our evaluation methodology to the SP ranking model. By being the dominant technique for either traditional or modern reliability-oriented solutions in the known literature [22][23][24][25][26][27], it poses as an excellent counterpart to our PaSS classification framework. We record the corresponding experimental results and compare their effectiveness in proactively suggesting reliable candidates for path mappings.…”

“…Reliable resource allocation can be achieved by either counteracting or precautionary orchestration, on the infrastructure or the slice level. The authors of [22] concentrate their efforts on the infrastructure plane. They developed a heuristic mapping algorithm to efficiently manage node failures in DWDMs' lightpaths.…”

“…In [24], the authors employ an adaptive path-splitting policy to provide full protection against single link failures with proactive partial backup reserves. Despite the promising experimental results of their heuristic strategy, their algorithm employs the SP mechanism to calculate the disjoint paths between obtained node pairs, similar to [22] and [23].…”

“…The authors of [23] try to reserve sufficient spare backup capacity in order to endure SN failures. Contrary to [22], their research focuses on providing reliability at the VN layer. They advocate that the utilization of shared idle backup resources, yields more resource efficient embeddings compared to the ones based on SN-oriented reliability methodologies.…”

The demand for connectivity in this fourth industrial revolution, is growing in an exponential rate. As the Fourth-Generation communication systems are replaced by the Fifth and Sixth-Generation ones, a plethora of fundamental performance issues need to constantly be addressed. Virtual network reliability is one of those main challenges for deploying resilient service-centric and user-centric scenarios in Next-Generation Networks. The need for strengthening critical applications dictates the emergence of mechanisms that could inherently produce more reliable resource allocations, either at the cloud or edge level. However, until the adoption of fully artificially intelligent management systems, the enhancement of existing resource evaluation and allocation mechanisms is mandatory during this transitional era. To reach this pressing milestone, we will have to revise the already deployed reliability frameworks, assessing their orchestrating stages. Our research focuses on providing a novel evaluation mechanism that could successfully replace traditional path choosing techniques in reliability prone algorithms, regardless of their orientation. The proposed synthesized metrics enumerate the candidate paths validly and optimally, by adhering to the Path Algebra fundamental properties of monotonicity and isotonicity. Such an implementation can be deployed seamlessly, either on legacy or modern architectures, cementing the innovative qualities of its design. The experimental results of our simulations indicate that the proposed solution favors substantially more reliable paths than its shortest-path counterpart.

Virtualization (NV) has been devised as one of the key bases of operativecloud systems. Commonly, Cloud Providers (CPs) seek to design their networkpolicy, especially in a distributed environment. Virtual Network Embedding(VNE) is a functional tool granted by the NV technologies that allow theCPs to manage their physical resources based on the received Virtual Networks(VNs). This paper focuses on the context when a given Virtual NetworkRequest (VNRs) needs to be shared among multiple Data Center Networks(DCNs). The proposed VNE solution executes a two-stage policy where at thefirst stage, the DCNs and VNRs have been managed through a greedy methodto solve the assignment problem. Then, we perform a greedy load-balancingalgorithm to accomplish the VNR mapping stage. The simulation results provedthat the proposed two methods outperformed the compared similar techniques.
