PSVShare: A Priority-based SFC placement with VNF Sharing
Amir Mohamad, Hossam S. Hassanein · 2020
Edge computing resources deployed at the access network are distributed and limited compared to the abundant core cloud resources. With the increasing demand on edge resources by emerging delay-sensitive use-cases, efficient resource utilization is to play an indispensable role. Taking advantage of operation dynamics and common functions in network/enterprise services, we propose PSVShare a priority-based, least-cost and resource-efficient service placement algorithm. The algorithm considers practical settings and conditions such as service categories (premium and best-effort), service arrival and completion times, and service relocation/migration due to changing traffic loads. PSVShare satisfies more services, achieves lower rejection rates, and is agnostic to arrival order and ratio of premium to best-effort services.
