“…Also aligned with ETSI-NFV architecture, FENDE marketplace [15] enables developers to offer their VNF-based services, while users can select Virtual Network Functions (VNFs) from the service and VNF catalogue, compose custom service chains and instantiate them in public or private cloud infrastructures. NECOS marketplace is a broker-based platform that enables the resource discovery, negotiation and selection for deploying network slice over multiple administrative domains [16], while the 5GEx platform focuses on cross-domain orchestration of network services [17]. With respect to the latter, a hierarchical architecture of multi-domain orchestrators enables the exchange of business-level information with customers, the service discovery and placement and supports the VNF configuration and monitoring.…”

With the advent of 5G verticals and the Internet of Things paradigm, Edge Computing has emerged as the most dominant service delivery architecture, placing augmented computing resources in the proximity of end users. The resource orchestration of edge clouds relies on the concept of network slicing, which provides logically isolated computing and network resources. However, though there is significant progress on the automation of the resource orchestration within a single cloud or edge cloud datacenter, the orchestration of multi-domain infrastructure or multi-administrative domain is still an open challenge. Towards exploiting the network service marketplace at its full capacity, while being aligned with ETSI Network Function Virtualization architecture, this article proposes a novel Blockchain-based service orchestrator that leverages the automation capabilities of smart contracts to establish cross-service communication between network slices of different tenants. In particular, we introduce a multi-tier architecture of a Blockchain-based network marketplace, and design the lifecycle of the cross-service orchestration. For the evaluation of the proposed approach, we set up cross-service communication in an edge cloud and we demonstrate that the orchestration overhead is less than other cross-service solutions.

“…We believe the CNS provider should continually monitor infrastructure providers and compile the best components from a marketplace [12] in order to offer custom end-to-end slice options for a specific tenant. In this sense, further studies on pricing models are needed to establish the financial viability of a CNS service.…”

“…In this sense, CNS can be defined as the process that enables isolated end-toend and on-demand networking abstractions, which: (a) contains both cloud and network resources, and (b) are independently controlled, managed and orchestrated [12]. such as very high throughput, large connection density or ultra-low latency.…”

Cloud Network Slicing is a new research area that brings together cloud computing and network slicing in an end-to-end environment. In this context, understanding the existing scientific contributions and gaps is crucial to driving new research in this field. This article presents a complete quantitative analysis of scientific publications on the Cloud Network Slicing, based on a systematic mapping study. The results indicate the situation of the last ten years in the research area, presenting data such as industry involvement, most cited articles, most active researchers, publications over the years, main places of publication, as well as well-developed areas and gaps. Future guidelines for scientific research are also discussed.

This paper explores and makes a case for allocating a Wide-area Infrastructure Manager (WIM) on-demand to support softwarized network slicing, as part of the full NFVI virtualised infrastructure foundation, to ensure that the connectivity attributes prescribed to network slices can be managed with flexibility and adaptability in a full end-to-end slice. We show how creating a WIM on-demand and dynamically allocating a new WIM for each network slice, rather than having one for the whole network, can be beneficial for various slicing scenarios, in a similar way that a Virtual Infrastructure Manager (VIM) on-demand has been utilized. The paper considers some of the components, abstractions, and mechanisms of WIM on-demand.
