“…SDN is developed to provide the flexibility that the control plane needs to support the traffic forwarding requirements of the data plane. According to the Open Network Foundation (ONF) [47], SDN is a dynamic architecture that promises to automate the network, centralize the control functions and program the network using APIs. Therefore, to achieve these objectives, SDN technology is based on three aspects: (1) separating the control plane and the data plane; (2) logically centralize the control plane [48]; (3) programing the control plane.…”

“…The SDN architecture defined by ONF [47] or International Telecommunication Union (ITU) [151] can be presented in 3 layers, namely the infrastructure layer, the control layer, and the application layer. For the interaction between these three layers, open Application Program Interfaces (APIs) are present.…”

Multi-access Edge Computing (MEC) is a key solution that enables operators to open their networks to new services and IT ecosystems to leverage edge-cloud benefits in their networks and systems. Located in close proximity from the end users and connected devices, MEC provides extremely low latency and high bandwidth while always enabling applications to leverage cloud capabilities as necessary. In this paper, we illustrate the integration of MEC into a current mobile networks' architecture as well as the transition mechanisms to migrate into a standard 5G network architecture. We also discuss SDN, NFV, SFC and network slicing as MEC enablers. Then, we provide a state-of-the-art study on the different approaches that optimize the MEC resources and its QoS parameters. In this regard, we classify these approaches based on the optimized resources and QoS parameters (i.e., processing, storage, memory, bandwidth, energy and latency). Finally, we propose an architectural framework for a MEC-NFV environment based on the standard SDN architecture.

The advancements in networking technologies have led to a new paradigm of controlling networks, with data plane programmability as a basis. This facility opens up many advantages, such as flexibility in packet processing and better network management, which leads to better security in the network. However, the current literature lacks network security solutions concerning authentication and preventing unauthorized access. In this work, our goal is to avoid attacks in a two level defense mechanism (P4Filter). The first level is a dynamic firewall logic, which blocks packets generated from an unauthorized source. The second level is an authentication mechanism based on dynamic port knocking. The two security levels were tested in a virtual environment with P4 based switches. The packets arriving at the switch from unknown hosts are sent to the controller. The controller maintains an ACL using which it assigns rules for both the levels to allow or drop the packets. For port knocking a new random sequence is generated for every new host. Hosts can only connect using the correct sequence assigned to them.The tests conducted show this approach performs better than the previous P4 based firewall approaches due to two security levels. Moreover, it is successful in mitigating specific security attacks by blocking unauthorized access to the network.
