“…This means that a SDN controller layer lacks the necessary policies to actively conducting mid-route changes when starting traffic forwarding. Considering NFV, the hypervisor provides the foundation for cloud computing with features that enable creation and deletion of VMs/VNFs, virtulized resources, multi-tenant environments, and different types of high volume virtual NICs [5]. To this point, policies defines the life cycle transitions for VMs and do not influence the underlying SDN layer to configure interworking between separated networks.…”

“…As the data plane is migrated into VM processing entities, the control plane becomes represented in the form of bare metal controllers that manage data forwarding between network slices. This network formulation provides the necessary components for an autonomic network with SDN that provide OpenFlow protocols to enable communication between the SDN controller and the network nodes on the southbound interface while providing control-application interfaces on the northbound interface [5]. However, this flexibility in managing network interfaces and diverting load flows remains isolated within the SDN domain or geo-datacenter.…”

The network function virtualization (NFV) transformation is gaining an incredible momentum from mobile operators as one of the significant solutions to improve the resource allocation and system scalability in fifth-generation (5G) networks. However, the ultra-dense deployments in 5G create high volumes of traffic that pushes the physical and virtual resources of cloud-based networks to edge limits. Consider a distributed cloud, replacing the core network with virtual entities in the form of virtual network functions (VNFs) still requires efficient integration with various underlying hardware technologies. Therefore, orchestrating the distribution of load between cloud geo-datacenters starts by instantiating a virtual and physical network typologies that connect involved fronthaul with relevant VNFs. In this article, we provide a framework to manage calls within 5G network clusters for efficient utilization of computational resources and also to prevent unnecessary signaling. We also propose a new scheme to instantiate virtual tunnels for call forwarding between network clusters leading to new logic networks that combine geo-datacenters and fronthaul. To facilitate service chaining in cloud, we propose a new enhanced management and orchestration (E-MANO) architecture that brings network traffic policies from the application layer to the fronthaul for instant monitoring of available resources. We provide analysis and testbed results in support of our proposals.

“…The solutions outlined above are able to control resources in SDN-oriented networks in real time, but without considering virtualization techniques and the flexibility obtained when the software implementation of NFs is decoupled from the underlying hardware. In this sense, Software-Defined Network Virtualization (SDNV) [16] is a framework that integrates the SDN and NFV techniques. This considers the SDN principle of separating data and control planes with NFV, decoupling service functions from infrastructures.…”

5G mobile networks are pushing new dynamic and flexible scenarios that demand the automation and optimization of network management processes. In this sense, Self-Organizing Networks (SON) arose to evolve from traditional manual management towards fully autonomic and dynamic processes. Due to the large volumes of data generated in 5G networks, functionalities and capabilities of SON require efficient processes and resource optimization techniques. In particular, self-protection is a critical capability of SON focused on protecting the network resources in a flexible and autonomic way. To achieve self-protection, SON perform different processes ranging from the monitoring of network communications to the analysis, detection, and mitigation of cyber-attacks. In this article, we propose an architecture that combines the Software Defined Networking (SDN) and Network Functions Virtualization (NFV) technologies to optimize the usage of network resources for monitoring services. A use case based on botnet detection in 5G networks shows how our architecture ensures the provision of monitoring services in managing self-protection scenarios. Additionally, we describe a set of experiments that confirm the best time calculated by our solution to deploy or reconfigure
