QoE Management Framework for Internet Services in SDN Enabled Mobile Networks

Abstract : In order to achieve acceptable service quality, the broad spectrum of Internet services requires differentiated handling and forwarding of the respective traffic flows in particular within increasingly overloaded mobile networks. The 3GPP procedures allow for such service differentiation by means of dedicated GPRS Tunnelling Protocol (GTP) tunnels, which need to be specifically set up and potentially updated based on the client initiated service traffic demand. The Software Defined Networking (SDN) enabled QoE monitoring and enforcement framework for Internet services presented in this paper is named ISAAR (Internet Service quality Assessment and Automatic Reaction) framework and will be abbreviated as ISAAR herein. It augments existing quality of service functions in mobile as well as software defined networks by flow based network centric quality of experience monitoring and enforcement functions. The following chapters state the current situation followed by the explanation of the ISAAR architecture in chapter 3 and its internal realisation in chapters 4, 5 and 6. In chapter 7 the summary and outlook are given.
