SELFNET Framework self‐healing capabilities for 5G mobile networks

Abstract

Nowadays, mobile networks are complex sets of heterogeneous equipments that use proprietary management applications, resulting in a huge expenditure, a large effort and a time‐consuming process to manage all network elements by means of currently manual or semi‐automatical approaches. With the emergency of new technologies, such software‐defined networking, network function virtualization, and cloud computing, the current configurable networks are capable of becoming programmable, which will facilitate advanced autonomous network management. This article presents capabilities of a novel framework proposed by the SELFNET project that enables highly autonomic management functionalities. It focuses on the proposed self‐healing use case that can be applied to reactively or preventively deal with the detected or predicted network failures. The SELFNET can provide the upcoming 5G system: an autonomic management framework, which brings a remarkable reduction upon operational expenditure and a substantial improvement of quality‐of‐experience(QoE) in terms of reliability, availability, service continuity and security.

Monitoring and Discovery for Self-Organized Network Management in Virtualized and Software Defined Networks

“…Similarly, the energy efficiency of the system can be analyzed to proactively managing the energy use of resources across the network. Meanwhile, the SELFNET Self-Healing Use Case [ 53 ] is applied to reactively or preventively deal with the detected or predicted network failures. The different metrics collected by the sensors give a global view of the available networking resources and services running on virtualized infrastructure.…”

Software Defined Networks in Wireless Sensor Architectures

“…A variation of Softair architecture is MyNet [ 80 ], a hierarchical deployment of controllers for 5G [ 81 ] networks that are responsible for each part of the network in order to reduce the control traffic flow. Yazici et al [ 82 ] also propose a hierarchical architecture titled CMaaS that manifests a four-layer controller hierarchy.…”

Network Management and Orchestration

“…For example, the SELFNET project has been set up to design, prototypically implement, and evaluate an autonomic management framework for 5G mobile networks. Taking advantage of new technologies, in particular Software-Defined Networking (SDN [38], Network Function Virtualization (NFV) [39], Self-Organized Network (SON) [40], Multi-access Edge Computing (MEC) and AI, the framework proposed by the SELFNET project can provide the capabilities of Self-Healing against network failures, Self-Protection against distributed cyber-attacks, and Self-Optimization to improve network performance and end users' QoE [41]. Although the current SON techniques have a self-managing function, it is limited to static network resources.…”
