Price and Performance of Cloud-hosted Virtual Network Functions: Analysis and Future Challenges

Abstract: The concept of Network Function Virtualization (NFV) has been introduced as a new paradigm in the recent few years. NFV offers a number of benefits including significantly increased maintainability and reduced deployment overhead. Several works have been done to optimize deployment (also called embedding) of virtual network functions (VNFs). However, no work to date has looked into optimizing the selection of cloud instances for a given VNF and its specific requirements. In this paper, we evaluate the performa… Show more

“…The number and size of the instances for each network function depend on several parameters like the demand (i.e., incoming traffic), the type of the function, the instance processing capacity (e.g., number of processed packets per second) and cost. The work of Ghrada et al, [29] provides some insights on how to select virtual machine instances based on the network function type, processing capacity and cost.…”

“…An analytical model based on queuing theory and Markov chains for cloud-based firewalls is presented in [11]. As a virtual network function (VNF), the performance of the network firewall for selection of cloud instance is evaluated in [12]. However, to the best of our knowledge, there is no research work which considers the batch arrival of packets.…”

“…NFV пропонує численні переваги для провайдерів телекомунікаційних сервісів, включаючи зниження вартості мережевого обладнання, мінімізацію споживання електроенергії, масштабованість, еластичність, повторне використання обладнання, легку мультитенантність та швидку конфігурацію нових послуг [6]. NFV сервіси складаються з набору мережевих функцій.…”
