“…• Abstraction -Abstraction provides a high-level overview of a network while hiding details of the underlying physical network entities (nodes, links, or networks) or resources [63]. This simplifies network management and facilitates flexible service provision; • Co-existence -Multiple virtual entities corresponding to a shared physical entity co-exist, or multiple virtual resource pools co-exist on the same physical resource pool [35].…”

In this tutorial paper, we look into the evolution and prospect of network architecture and propose a novel conceptual architecture for the 6th generation (6G) networks. The proposed architecture has two key elements, i.e., holistic network virtualization and pervasive artificial intelligence (AI). The holistic network virtualization consists of network slicing and digital twin, from the aspects of service provision and service demand, respectively, to incorporate service-centric and usercentric networking. The pervasive network intelligence integrates AI into future networks from the perspectives of networking for AI and AI for networking, respectively. Building on holistic network virtualization and pervasive network intelligence, the proposed architecture can facilitate three types of interplay, i.e., the interplay between digital twin and network slicing paradigms, between model-driven and data-driven methods for network management, and between virtualization and AI, to maximize the flexibility, scalability, adaptivity, and intelligence for 6G networks. We also identify challenges and open issues related to the proposed architecture. By providing our vision, we aim to inspire further discussions and developments on the potential architecture of 6G.

“…Similar concepts appeared earlier in the context of the IRMOS European project [41], where real-time scheduling of virtual machines deployed with the KVM hosted (Type-2) hypervisor was integrated within a comprehensive cloud management solution for guaranteed resource provisioning to service-oriented real-time and multimedia applications. A fundamental brick of the IRMOS architecture was the so called Intelligent Service-Oriented Infrastracture (ISONI) [42], an abstraction layer able to deploy an arbitrary topology of VMs with precise individual as well as endto-end QoS requirements, called a Virtual Service Network (VSN), within a computing and networking infrastructure capable of providing precise computational and networking guarantees. This was possible thanks to the combination of real-time scheduling of VMs with QoS-aware networking protocols.…”

In this paper, the problem of temporal isolation among containerized software components running in shared cloud infrastructures is tackled, proposing an approach based on hierarchical real-time CPU scheduling. This allows for reserving a precise share of the available computing power for each container deployed in a multi-core server, so to provide it with a stable performance, independently from the load of other co-located containers. The proposed technique enables the use of reliable modeling techniques for end-to-end service chains that are effective in controlling the application-level performance. An implementation of the technique within the well-known OpenStack cloud orchestration software is presented, focusing on a use-case framed in the context of network function virtualization. The modified OpenStack is capable of leveraging the special real-time scheduling features made available in the underlying Linux operating system through a patch to the in-kernel process scheduler. The effectiveness of the technique is validated by gathering performance data from two applications running in a real test-bed with the mentioned modifications to OpenStack and the Linux kernel. A performance model is developed that tightly models the application behavior under a variety of conditions. Extensive experimentation shows that the proposed mechanism is successful in guaranteeing isolation of individual containerized activities on the platform.

“…The key question highlights platform standardization, improvement of the platform flexibility and dynamic scalability, reduction of the degree of coupling of platform components and other aspects. There are many virtualization technology researches and explorations: Research [4] and [5] put forward virtualization platform architecture through researches based on service-oriented architecture (SOA), [6] and [7] focus on platform flexibility and dynamic capacity expansion, [8,9,10] study on virtualization from storage virtualization, virtual device, network virtualization, and other aspects.…”

In order to meet the requirements of standardization of virtualization in cloud computing platform, improve the flexibility and expansibility of the system and enhance the capability of management-control of the platform, by means of introducing the features of decoupling and semantic of metadata, a Metadata-driven Cloud Computing Application Virtualization Model(MCCAVM) in software level is proposed in the paper based on Turing machine model and Von Neumann computer architecture. The model achieves the complete life cycle management of the capabilities and services. Based on the formal definition, analyzing the hierarchical structure with multi-role and multi-dimensional view, the paper proposes a Metadata-driven Cloud Computing Application Virtualization System(MCCAVS). Taking the production of virtual cloud storage service as example, this paper gives formal analysis of system running and compares with other relating work. The results show that the model presents good reference on the construction of cloud computing application virtualization platform.
