Abstract

Edge as a Service (EaaS) is a promising approach to increase the management capacity of Internet Service Providers (ISPs) and to support QoS/QoE for their clients. EaaS uses Virtual Networks (VNs) to ease the management of ISPs. Thus, EaaS needs an algorithm to define virtual topologies for the VNs considering the resource utilization, the energy consumption and the service delivery reliability. Within this context, this paper presents Fuzzy for Allocation (FUZA) algorithm to define reliable virtual topologies for EaaS. FUZA is based on a fuzzy system and uses energy consumption and bandwidth availability to define the most suitable virtual topology for the VN requested. The results suggest that the proposed algorithm can deploy reliable VNs, while improving bandwidth utilization and energy consumption of the network infrastructure.
