A QoS-Aware Software Defined Mobility Architecture for Named Data Networking

Abstract

Named Data Networking (NDN) is a future architecture for the internet and is an inventive model to provide content-based services. The unique properties of NDN, like naming schemes for network packets and approaches for in-network caching, makes it more reasonable for content distribution. However, extreme changes are required in the existing network infrastructure in order to implement NDN on it. One of the primary research dimensions for this new internet architecture is mobility. Although some research work has been done to address mobility concerns, there are still mobility issues like maintaining the connection establishment by frequently changing the position of users, loss of interest and data packets, interest and data packet transmission and re-transmission without any correspondence delay. One of the reasonable approaches is the Software Defined Networking (SDN) technique, which is used to realize mobility management for NDN. The core concept of SDN is the separation of the network control plane from the data plane. The data plane is capable of data forwarding, whereas the control plane is responsible for the entire network's control. The network control plane is decoupled from the data plane, resulting in a more programmable environment and the ability for external software to define a network's behavior. The SDN's main features, such as programmability, flexibility, and centralized control, make it a simple and scalable network. To cope with the issue of NDN mobility, we propose the design of a software-defined mobility architecture for NDN in which the SDN paradigm is extended to support mobility handling in the NDN architecture. Moreover, the intra-domain and Inter-domain handover handling scenarios in the software-defined mobility architecture for NDN have been described.
