In this paper, we propose a multilayer self‐diagnosis framework for network services within the software‐defined networking and network functions virtualization environments. The framework encompasses 3 main contributions: (1) the definition of multilayered templates to identify the components to supervise across the physical, logical, virtual, and service layers. These templates are also finer‐granular,...
In this paper, we propose a multi-layer self-diagnosis framework for networking services within SDN and NFV environments. The framework encompasses three main contributions: 1) the definition of multi-layered templates to identify what to supervise while taking into account the physical, logical, virtual and service layers. These templates are also finer-granular, extendable and machine-readable;...
This paper proposes the medium-long term vision where Telecommunications networks will evolve towards becoming Software Defined Infrastructures (SDI). In particular, SDI will be highly dynamic and pervasive environments of logical resources capable of executing any network and service function (e.g., from L2 to L7) developed and controlled as software applications. It is argued that SDI will be a...
Networks built using SDN (Software-Defined Networks) and NFV (Network Functions Virtualization) approaches are expected to face several challenges such as scalability, robustness and resiliency. In this paper, we propose a self-modeling based diagnosis to enable resilient networks in the context of SDN and NFV. We focus on solving two major problems: On the one hand, we lack today of a model or template...
The meaning of 5G is still a subject of discussion in the industry. However, the softwarization of networks is expected to shape the design, operation and management of 5G networks. The opportunity is then crucial for Telcos, vendors and IT players to consider the management of 5G networks during its design time and avoid the “build it first, manage it later” paradigm. However, network softwarization...
Technology advances are making available huge amounts of processing, storage, networking capabilities at the edge (i.e., up to End-Users premises) of current networks. It is argued that these trends, coupled with new emerging paradigms such as Software Defined Networks, will impact deeply the evolution of future networks, allowing to design highly flexible architectures at the edge capable of creating...
