Network Slicing for 5G: Challenges and Opportunities more. Network slicing for 5G is receiving significant attention from the telecommunications industry as a means to provide network as a service NaaS for different use cases. Network slicing is a technology which allows network operators to Network slicing is a technology which allows network operators to build multiple virtual networks on a shared infrastructure.

With network slicing, service providers can deploy their applications and services flexibly and quickly to accommodate specific requirements of diverse services such as augmented reality, online games, e-health and others. As an emerging technology with a number of advantages, network slicing has raised many issues for the industry and academia alike.

In this article, we discuss the background and related work in network slicing and propose a framework for 5G network slicing. Finally, we discuss the challenges of network slicing and future research directions.

Doi: This article surveys blockchain-based approaches for several security services. These services include authentication, confidentiality, privacy and access control list ACL , data and resource provenance, and integrity assurance. All these services are critical for the current distributed applications, especially due to the large amount of data being processed over the networks and the use of cloud computing.

Confidentiality guarantees that data cannot be read by unauthorized users. Privacy provides the users the ability to control who can access their data. Provenance allows an efficient tracking of the data and resources along with their ownership and utilization over the network. Integrity helps in verifying that the data has not been modified or altered. These services are currently managed by centralized controllers, for example, a certificate authority. Therefore, the services are prone to attacks on the centralized controller.

On the other hand, blockchain is a secured and distributed ledger that can help resolve many of the problems with centralization. The objectives of this paper are to give insights on the use of security services for current applications, to highlight the state of the art techniques that are currently used to provide these services, to describe their challenges, and to discuss how the blockchain technology can resolve these challenges.

Further, several blockchain-based approaches providing such security services are compared thoroughly. Challenges associated with using blockchain-based security services are also discussed to spur further research in this area. Fault and performance management systems, in the traditional carrier networks, are based on rule-based diagnostics that correlates alarms and other markers to detect and localize faults and performance issues.

As carriers move to Virtual As carriers move to Virtual Network Services, based on Network Function Virtualization and multi-cloud, the traditional methods fail to deliver because of the impalpability of the constituent Virtual Network Functions and increased complexity of the resulting architecture.

In this paper, we propose a framework, called HYPER-VINES, that interfaces with various management platforms involved, to process markers, through a system of shallow and deep machine learning models, to detect and localize manifested and impending fault and performance issues. Our experiments validate the functionality and feasibility of the framework in terms of accurate detection and localization of such issues and unambiguous prediction of impending issues.

Simulations with real network fault datasets show effectiveness of its architecture in large networks. Deployment of Network Function Virtualization NFV over multiple clouds accentuates its advantages like flexibility of virtualization, proximity to customers and lower total cost of operation.

However, NFV over multiple clouds has not However, NFV over multiple clouds has not yet attained the level of performance to be a viable replacement for traditional networks. In NFV, faults and performance issues can have complex geneses within virtual resources as well as virtual networks and cannot be effectively handled by traditional rulebased systems. In the train model, the traffic on the network consists of a number of packet streams between various pairs of nodes on the network.

Each node-pair stream or node-pair process, as we call them consists of a number of trains. Satellite networks play an indispensable role in providing global Internet access and electronic connectivity.

To achieve such global communications, provisioning of quality of service QoS within the advanced satellite systems is the To achieve such global communications, provisioning of quality of service QoS within the advanced satellite systems is the main requirement.

One of the key mechanisms of implementing the quality of service is traffic management. Traffic management becomes a crucial factor in the case of satellite network because of the limited availability of their resources.
