NFV and SDN-Based Differentiated Traffic Treatment for Residential Networks

Abstract

Residential networks play a critical role in assuring that services or applications such as tele-work, tele-education, medical care, entertainment, home automation, among others, have the required resources to obtain an optimal performance. Although current residential gateways try to meet the Quality of Service (QoS) demands, the traditional networking paradigm does not have the appropriate mechanisms to address the heterogeneous and dynamic nature of the services running at home. In this context, a feasible solution consists of leveraging the flexibility and adaptability of the Software Defined Networking (SDN) and Network Functions Virtualization (NFV) paradigms to provide a differentiated traffic treatment intended to improve the QoS support of residential networks. The proposal takes advantage of the Service Function Chaining (SFC) concept intrinsic to NFV as well as the capacity of an SDN-based residential gateway to differentiate the traffic of a certain application. Thus, an association between an SFC and the differentiated traffic is stablished to apply a specific treatment. Besides, a comprehensive architecture composed of the software defined residential network (SDRN), the software defined access network (SDOAN) and the NFV-compliant ISP's edge cloud infrastructure is envisioned. This architecture would allow dramatically improving the life cycle management of the residential network from a centralized point which follows a user-centric approach.

A comprehensive survey of performance, security and privacy issues in the network interface layer of the TCP/IP

“…Researchers have identified and proposed mitigation mechanisms on various vulnerabilities in the network interface, such as Address Resolution Protocol (ARP) spoofing, Media Access Control (MAC) address spoofing, and Denial-of-Service (DoS) attacks [17]- [20]. Traffic sniffing, network intrusion detection, and user tracking in the network interface layer raise privacy concerns that researchers are actively addressing [21]- [24].…”

Software defined networking agent demonstration to enable configuration and management of XGS-PON architectures

“…Other SDN proposals focus on managing residential networks in PON architectures, due to the growing number of connected devices in users' homes and applications with high QoS requirements [14,28]. Regarding protection and energy saving in PONs, an SDN-based architecture was implemented in [29] to allow fast feeder fiber protection over PONs.…”
