An Analytical Model to Design and Manage a Green SDN/NFV CPE Node

Abstract

In the last few years SDN and NFV have been introduced with the potential to change the ossified Internet paradigm, with the final goal of creating a more agile and flexible network, at the same time reducing both CAPEX and OPEX costs. For this reason, a lot of research efforts have been devoted to optimize the implementation of these technologies, also inheriting experience from data center management. However, orchestration and management of SDN/NFV nodes present new challenges in respect of data center management, mainly due to the telecommunications context where NFV resides. With this in mind, the target of this paper is to define a management model for NFV customers and service providers, a green policy of the Customer Premises Equipment (CPE) nodes, and an analytical model to support their design. The model is then applied to a case study to demonstrate how it can be used to optimize system performance and choose the most important parameters characterizing the design of a CPE node.

Towards energy efficiency and green network infrastructure deployment in Nepal using software defined IPv6 network paradigm

“…Network function virtualization (Faraci & Schembra, ) and server virtualizations help reduce the energy consumption in a network (Bolla, Lombardo, Bruschi, & Mangialardi, ). The software and network operations previously run in the separate commodity hardware can be moved and relocated to a single hardware with virtualization technologies.…”

FOGPLAN: A Lightweight QoS-Aware Dynamic Fog Service Provisioning Framework

“…Fog nodes can be routers, switches, dedicated servers for fog computing (e.g. cloudlets), customer premises equipment (CPE) nodes (also called home gateways), or firewalls [7][39] [40]. The fog nodes can be either small-scale nodes in a residential environment (e.g.…”

“…home gateways), or medium/ high-performance equipment in an enterprise environment (e.g. routers or aggregation nodes of a Telco network) [39].…”

SDN, slicing, and NFV paradigms for a smart home: A comprehensive survey

“…The distributed model considers the deployment of VNFs at the local consumer premise equipment. Faraci and Schembra argued that, in the future, it could also be interesting to put “micro data center” in a residential environment (consumer premise equipment (CPE)) as we assist to an exponential growth in the number of connected home devices. A centralized manager at the edge or the cloud orchestrates the distributed VNFs.…”

“…The main idea is evolving the home gateway to a simple bridge (low layer connectivity) between the home network and the access network and virtualizing the advanced features such as firewall, parental control, etc. 53,54 Recent research works 55,56,[65][66][67][68][69][70][71][72][73] combined SDN and NFV to provide not only a flexible management of the home network but also a faster deployment of new revenue-generating services. This architecture aims to reduce the OpEX and CapEX costs.…”
