“…As stated in Section 3, the comparison with other research is difficult because the figures change considerably even when comparing the basic split per component. Furthermore, most related works provide qualitative analysis (such as those by Lobillo et al, Mäkinen, and Li et al) and/or focus on other parameters (scalability or elasticity of the network).…”

The changes in new mobile networks toward a full Internet protocol-based architecture have led to opportunities for service-oriented optimizations based on emergent technologies like fog computing, software-defined networking, or network function virtualization. This paper explores 2 ways of using these new technologies to reduce the latency in Long-Term Evolution (LTE) networks. Both solutions reduce the path that the data packets should follow from the base station (evolved Node B [eNB]) to the network components that connect to the servers. The first solution, called Fog Gateway, is based on the interception of the packets in the tunnel at the eNB and their redirection to local servers running the fog services. This solution is fully compliant with the current LTE architecture and only requires new components. The second solution, called General Packet Radio Service Tunneling Protocol Gateway (GTP), is based on splitting the eNB's functionality to avoid unnecessary GTP encapsulation of the packets geared toward the fog services. This paper includes an analysis of the latency split in LTE networks, the evaluation of both solutions with experiments in an end-to-end LTE network testbed, and a discussion around their applicability in future fifth-generation networks. The results confirm that they are feasible to provide low-latency services and that they are compatible with some of the emergent paradigms (software-defined networking and network function virtualization) as well as with the studies on fifth-generation networks from the standardization bodies.

“…Heinonen et al [7], demonstrate another possibility that splitting the control and data planes opens, namely, free choice of data plane transport path. They show that data plane traffic can be switched dynamically to go through either hardware or software switches.…”

“…Several proposals [76][77][78][79][80] leverage the SDN concept into mobile core gateways. In [76], the authors made an analysis of all mobile core gateways' functions and then mapped them into four alternative deployment frameworks based on SDN and Openflow including full cloud migration, control-plane cloud migration, signaling control cloud migration and scenario-based cloud migration.…”

“…As an extension of the work in [77,78] proposed power saving models to maximize power savings by adapting the datacenter operation according to the time-varying traffic patterns and datacenter resources. The authors in [79,80] similarly adopted SDN and NFV into EPC S/PGWs. In these works, the control function of an S/P integrated gateway (S/PGW) is decoupled from the user plane.…”

Software-defined networking (SDN) features the decoupling of the control plane and data plane, a programmable network and virtualization, which enables network infrastructure sharing and the ''softwarization'' of the network functions. Recently, many research works have tried to redesign the traditional mobile network using two of these concepts in order to deal with the challenges faced by mobile operators, such as the rapid growth of mobile traffic and new services. In this paper, we first provide an overview of SDN, network virtualization, and network function virtualization, and then describe the current LTE mobile network architecture as well as its challenges and issues. By analyzing and categorizing a wide range of the latest research works on SDN and virtualization in LTE mobile networks, we present a general architecture for SDN and virtualization in mobile networks (called SDVMN) and then propose a hierarchical taxonomy based on the different levels of the carrier network. We also present an in-depth analysis about changes related to protocol operation and architecture when adopting SDN and virtualization in mobile networks. In addition, we list specific use cases and applications that benefit from SDVMN. Last but not least, we discuss the open issues and future research directions of SDVMN.
