“…Requirements for 5G mobile networks include a higher flexibility and scalability of the network, and an x100 increase in cost effectiveness and energy efficiency compared to its predecessor, the Long Term Evolution (LTE) technology [1]. Toward these goals, new paradigms such as Software Defined Networking (SDN) and Network Functions Virtualization (NFV) have been adopted in recent proposals for mobile network architectures [2] [3] [4] [5], and they are expected to play a vital role in 5G networks.…”

Requirements for 5G mobile networks includes a higher flexibility, scalability, cost effectiveness and energy efficiency. Towards these goals, Software Defined Networking (SDN) and Network Functions Virtualization have been adopted in recent proposals for future mobile networks architectures because they are considered critical technologies for 5G. In this paper, we propose an X2-based handover implementation in an SDNbased and partially virtualized LTE architecture. Moreover, the architecture considered operates at link level, which provides lower latency and higher scalability. In our implementation, we use MPLS tunnels for user plane instead of GTP-U protocol, which introduces a significant overhead. To verify the correct operation of our system, we developed a simulator. It implements the messages exchange and processing of the primary network entities. Using this tool we measured the handover preparation and completion times, whose estimated values were roughly 6.94 ms and 8.31 ms, respectively, according to our experimental setup. These latencies meet the expected requirements concerning control plane delay budgets for 5G networks.

“…Another effort of addressing backward compatibility issue is presented in [63] where a 4G mobile communication system is shown to be used as a SDN-based mobile network via the separation of Edge Control Plane (ECP) and edge switches from the 4G core network. ECP contains all the intelligence and LTE control plane, i.e., MME, HSS, PCRF, etc., where as the 4G network only performs packet transmission.…”

“…The access nodes, i.e., eNodeB, remain unchanged. [63] also talks about serving 3G and WiFi nodes through similar SDN-fixed 4G network. This scheme is a good proposal for first step towards the full SDN implementation but it requires substantial management rework in 4G networks.…”

“…This scheme is a good proposal for first step towards the full SDN implementation but it requires substantial management rework in 4G networks. It is yet to see if it will make a good business case to revamp the control plane of already erected 4G network or will it be easier to install the new 5G systems, already arriving in the market, with similar SDN fixes as in [63]. The proposed SDN-based mobile network architecture in [64] maintains the 3GPP interfaces so the architecture can also be used with legacy network.…”

For many, this is no longer a valid question and the case is considered settled with SDN/NFV (Software Defined Networking/Network Function Virtualization) providing the inevitable innovation enablers towards the realization of a virtualized, flexible, programmable and flexible 5G network. As SDN along with other technology enablers (including NFV) are still in the process of evolution, the first commercial deployment of 5G may take few years. However, some companies are claiming the availability of 5G solutions, but considering the monumental task of softwarization of mobile cellular networks there are genuine concerns that we may only see some point solutions involving SDN technology instead of a fully virtualized SDN-enabled 5G mobile network. In order to determine the technology readiness of SDN solutions in the context of 5G networks, this survey paper attempts to identify all important obstacles in the way, and looks at the state of the art of the relevant research. This survey is different from the previous surveys on SDN-based mobile networks as it focuses on the salient problems and discusses solutions proposed within and outside SDN literature. Our main focus is on fronthaul, backward compatibility, supposedly disruptive nature of SDN deployment, business cases and monetization of SDN related upgrades, latency of general purpose processors (GPP), and additional security vulnerabilities that softwarization brings along to the mobile network. We have also provided a summary of the architectural developments in SDN-based mobile network landscape, including deployment options for SDN within NFV framework, as not all work can be covered under the focused issues. This paper provides a comprehensive survey on the state of the art of SDNbased mobile networks and clearly points out the gaps in the technology.
