“…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.…”

Living in a smart home is an entirely new experience, which enhances our everyday life. Many manufactures and internet of things service providers developed their own smart home services from which the customer can benefit from running a software over his smartphone or tablet. Today, it is becoming increasingly complex for the homeowner to control and manage the growing number of heterogeneous home connected devices through a multitude of available services. Several researchers proposed to improve the home area network design by introducing the software defined networking approach. Although, the software‐defined network (SDN) approach has many advantages, combining it with other approaches like slicing and network function virtualization can give more benefits such as improving the quality of service and the quality of experience, the management, and the control of the network. In this review, we present and discuss recent works that improve the design of the home area network considering SDN or a combination of SDN with slicing and network function virtualization.

Value-added services (e.g., overlaid video advertisements) have become an integral part of today's Content Delivery Networks (CDNs). To offer cost-efficient, scalable and more agile provisioning of new value-added services in CDNs, Network Functions Virtualization (NFV) paradigm may be leveraged to allow implementation of fine-grained services as a chain of Virtual Network Functions (VNFs) to be placed in CDN. The manner in which these chains are placed is critical as it both affects the quality of service (QoS) and provider cost. The problem is however, very challenging due to the specifics of the chains (e.g., one of their end-points is not known prior to the placement). We formulate it as an Integer Linear Program (ILP) and propose a cost efficient Proactive VNF placement and chaining (CPVNF) algorithm. The objective is to find the optimal number of VNFs along with their locations in such a manner that the cost is minimized while QoS is met. Apart from cost minimization, the support for large-scale CDNs with a large number of servers and end-users is an important feature of the proposed algorithm. Through simulations, the algorithm's behavior for small-scale to large-scale CDN networks is analyzed.

“…Taking advantage of centralized cloud services in the core networks has benefits [6] because of scalable and flexible computing capabilities. However, large-number deployments of Internet-of-Things (IoT) devices bring challenges to VNFs running in a centralized cloud, as the network traffic load would be drastically increased by transmitting data between the core and the edge of the network.…”

For embracing the ubiquitous Internet-of-Things (IoT) devices, edge computing and Network Function Virtualization (NFV) have been enabled in branch offices and homes in the form of virtual Customer-Premises Equipment (vCPE). A Service Provider (SP) deploys vCPE instances as Virtual Network Functions (VNFs) on top of generic physical Customer-Premises Equipment (pCPE) to ease administration. Upon a usage surge of IoT devices at a certain part of the network, vCPU, memory, and other resource limitations of a single pCPE node make it difficult to add new services handling the high demand. In this paper, we present IoT-B&B, a novel architecture featuring resource sharing of pCPE nodes. When a pCPE node has sharable resources available, the SP will utilize its free resources as a "bed-and-breakfast" place to deploy vCPE instances in need. A placement algorithm is also presented to assign vCPE instances to a cost-efficient pCPE node. By keeping vCPE instances at the network edge, their costs of hosting are reduced. Meanwhile, the transmission latencies are maintained at acceptable levels for processing real-time data burst from IoT devices. The traffic load to the remote, centralized cloud can be substantially reduced.
