“…where such issues should be revisited given the new architecture for both possible benefits and challenges. [Hampel et al 2013] argued that SDN can be an effective architecture to solve problems in mobile networks. They proposed vertical forwarding as an extension to current OpenFlow to handle mobility policy or access control management or in particular fine grained forwarding.…”

Network technologies have always been a crucial part of success for technologies like cloud computing. But due to the slow development of a scalable IT infrastructure, this can lead to issues in competitiveness. Software defined networking (SDN) can thereby counteract such issues by giving new functions to the whole network topology. With SDN, administrators have the possibility to abstract the underlying network infrastructure for applications and network services. The paper reports on the main outcomes of a systematic literature review on challenges and effects of SDN. It shows that most papers address the implementation of software defined networking as a challenge, including factors like vendor lock-in and the general risk of changing traditional network architectures. Attention is also given to security issues arising with software defined networks and the permanent high demand from the end-user combined with the fear of changing traditional networks. Issues dealing with specialized know-how were identified as another challenge category. Effects of SDN are discussed by defining unique features of SDN like decoupling hardware from the software and the global view of the whole network architecture. SDN furthermore affects the management of the network, including changes in deployment of policies, the programmability and maintenance of the network. Economic factors, such as cost efficiency and reduction of costs, are also discussed.

“…Such a tunnelingenabled OpenFlow switch is also discussed in [16], based on which the authors discussed the feasibility to split EPC functions: part of them (like control functions) are running in a datacenter, part of them (like tunneling) are kept in the transport network. In [17], the authors proposed a vertical forwarding scheme, which handles system scalability by allowing the controller to create flows using only a few controllable forwarding elements with tunneling capability. However, the network forwarding elements are also specialized hardware with tunneling capability integrated.…”

The gateways in mobile cellular networks are capable to handle the traffic from millions of subscribers at the same time, while providing high availability guarantee. Such entities are not only expensive, but also inflexible in terms of system deployment and maintenance. In this work, we investigate the feasibilities to virtualize gateway entities used in the Long Term Evolution (LTE) Evolved Packet Core (EPC). We propose a novel PDN Gateway (PGW) architecture, which decouples the control plane from the user plane by using Software Defined Network (SDN) technology. Moreover, we propose to run the user plane forwarding function on low cost IT hardware. The major advantages of our proposal are two-fold. First, our proposal lowers down the expenditure of operating services in LTE networks. Second, fine-grained resource management policies can be implemented in our virtualized gateway, which brings agility and reliability for the mobile cellular network.
