Maximizing Throughput of Delay-Sensitive NFV-Enabled Request Admissions via Virtualized Network Function Placement

Abstract: Network Function Virtualization (NFV) has attracted significant attention from both industry and academia as an important paradigm change in network service provisioning. Most existing studies on admissions of NFV-enabled requests focused on deploying dedicated Virtualized Network Function (VNF) instances to serve each individual request without exploring VNF instances sharing among multiple user requests. However, with every-growing user service demands, exclusive usages of VNF instances in most networks dras… Show more

“…A heuristic algorithm is proposed to solve this problem in [5]. In [25]- [26], the servers and physical links are allocated to SFCs such that as many as possible SFC requests are admitted. Authors in [25] proposed an online heuristic algorithm to maximize the number of admitted SFCs satisfying the endto-end transmission delay requirement.…”

“…In [25]- [26], the servers and physical links are allocated to SFCs such that as many as possible SFC requests are admitted. Authors in [25] proposed an online heuristic algorithm to maximize the number of admitted SFCs satisfying the endto-end transmission delay requirement. In [26], the NFV-RA problem is formulated as a multi-objective problem to maximize the number of admitted SFCs and minimize the amount of utilized resources, simultaneously.…”

“…A different approach is adopted in [14], [15], [16], [17], [18], [19], [20] where VNF placement can be readjusted through VNF sharing and migration, to optimally fit timevarying service demands. [14] and [15] propose algorithms that properly scale over-utilized or under-utilized VNF instances based on the estimation of future service demands.…”

“…Request admission control has instead been considered in [17], [18], [19], [20]. More in detail, Li et al [17] propose a proactive algorithm that dynamically provisions resources to admit as many requests as possible with a timing guarantee.…”
