Survey on Machine Learning-Enabled Network Slicing: Covering the Entire Life Cycle

/

Network slicing (NS) is becoming an essential element of service management and orchestration in communication networks, starting from mobile cellular networks and extending to a global initiative. NS can reshape the deployment and operation of traditional services, support the introduction of new ones, vastly advance how resource allocation performs in networks, and notably change the user experience. Most of these promises still need to reach the real world, but they have already demonstrated their capabilities in many experimental infrastructures. However, complexity, scale, and dynamism are pressuring for a Machine Learning (ML)-enabled NS approach in which autonomy and efficiency are critical features. This trend is relatively new but growing fast and attracting much attention. This article surveys Artificial Intelligence-enabled NS and its potential use in current and future infrastructures. We have covered state-of-the-art ML-enabled NS for all network segments and organized the literature according to the phases of the NS life cycle. We also discuss challenges and opportunities in research on this topic.

Solução Autônoma de Auditoria de Acordos de Nível de Serviço para Fatiamento de Recursos em Multi-Mercados Baseada em Blockchain

The Slice as a Service (SlaaS) paradigm offers promising opportunities to support various enterprises and institutions that have been using cloud computing to reduce costs and connect their network across different administrative domains. The Novel Enablers for Cloud Slicing (NECOS) platform presents a distributed market model that dynamically creates network slices in the cloud involving different slice resource providers. Proper selection, negotiation, and monitoring of service level agreement applications across multiple administrative and technology domains are among the key challenges for realizing a distributed marketplace of large network resource providers. This paper proposes an SLA compliance auditing model for blockchain-based network resource slicing for transparent and distributed monitoring using smart contracts.

Proposta de planejamento, gerência e otimização de recursos de redes em tempo de execução utilizando Gêmeo Digital

/

The Digital Twin is a promising concept, which is being adopted by several industrie by integrating a number of technologies. However, the adoption of this approach in computer networks is still timidy. Thus, this paper proposes a digital twin system structured in four layer that uses a multilayer SDN testbed as the physical entity, the CNetLab emulator as the digital twin and a data processing environment as the intermediate layer establishing a bidirectional connection between these environments.

Desafios e Oportunidades rumo à Internet Quântica

/

To exchange data over long distances, in topologically complex networks built on heterogeneous technologies and managed by independent organizations, methods that allow quantum protocols to transparently connect to the underlying hardware implementations are required. However, quantum signals are fragile and cannot be copied or amplified. Until today, just some preliminary versions of network stacks for a quantum internet have been proposed, and only a few basic elements have been suggested. To fully realize the potentials of quantum communication, new challenges and open issues need to be addressed. This paper presents key challenges to enabling a quantum Internet and discusses possible alternatives that are being developed.

DASP: Distributed and Autonomic Scientific Publisher Proposal for Editorial Process Management on Permissioned Blockchain

/

This paper presents an open-source Distributed Autonomic Scientific Publisher, which works on a permissioned blockchain network, automatically organized through a smart contract that organizes the whole business logic of the tool, allowing the auditing of the whole process, ensuring the copyrights for the students involved in the publication of each article, besides reducing the implementation costs and the complexity of the editorial mechanisms. The proof of concept was developed as an editorial management tool with the basic processes of submission, review, and evaluation.
