“…Microsoft RDS virtual desktop technology to improve and manage the laboratory in a centralized manner, and the design is based on the total scale of 800 users and 500 concurrent users in the early stage [12]. The virtual desktop user resource configuration is as follows: 4G memory, 2vCPU, 50 GB system space, 10 GB user data storage space, and resource expansion will be carried out gradually.…”

In order to solve the problems faced in the process of laboratory construction and management, the author proposes a complete laboratory cloud desktop virtualization management platform. The platform combines the school’s existing experimental teaching environment and teaching mode, through actual deployment and online monitoring; it is further verified that the cloud desktop platform not only provides personalized desktop services but also realizes unified management of resources. Experimental results show that the system function tests are all in line with expectations; during the network bandwidth test, the thin client protocol machine is used to access the cloud platform, and the Thunder player is opened to play the movie application, and then, the thin client machine uses RDP to access the cloud platform; when RDP is playing a movie, the traffic is mainly in the range of 1.2~1.6 Mbps, and the network delay is less than 1.3 s. Through research, it is found that the platform enhances students’ learning initiative, improves teaching management level, and has high experimental teaching application value.

“…The Function controller, through the interaction between the TC and the IC in each data center, can indirectly interact with the networking infrastructure of each data center, that is, the router acting as data center gateway (connecting to the WAN) and the leaf and spine switches that typically serve to interconnect the compute nodes hosting the functions. This interaction can happen for instance to accompany scaling events at the service function side (e.g., [22,23]), thus ensuring that the connectivity associated to the capacity of the network function does not become a bottleneck or, on the contrary, that some connectivity resources can be released, if needed.…”

Network slicing will permit offering to vertical customers tailored end-to-end logical networks in an on-demand fashion, on top of a common telecom infrastructure, achieving a Slices-as-a-Service (SlaaS) business model. This is possible due to the progressive introduction of network softwarization techniques, such as programmability and virtualization, into existing operational networks, enabling dynamic and flexible provision of slices. Those vertical customers could require the control not only of the network functions composing the end-to-end service, but also of the connectivity among them, e.g., for influencing the paths for steering traffic among function instances. However, this can be problematic since decisions from one vertical customer can collide with decisions from others. One aspect not yet sufficiently investigated is how to permit vertical customers to jointly control the service functions and the underlay connectivity, in such a way that could operate the allocated slice as if it was actually a dedicated network entirely for them. This paper explores some architectural proposition in this respect illustrated with some potential use cases and it provides an example of the provision of SlaaS for a vertical customer.

“…A elasticidade vertical lida com a flutuac ¸ão da demanda aumentando ou reduzindo os recursos da máquina utilizada pelo servic ¸o. A elasticidade horizontal propõe a criac ¸ão de uma ou mais instâncias virtuais com as mesmas configurac ¸ões da máquina original, distribuindo a demanda para essas instâncias virtuais que executam o servic ¸o [Arteaga et al 2020]. Entretanto, ferramentas de orquestrac ¸ão de computac ¸ão em nuvem, incluindo Kubernetes, não foram projetadas para suportar nativamente os servic ¸os de telecomunicac ¸ões.…”

Os avanços tecnológicos na quinta geração (5G) de redes móveis estão alicerçados em plataformas nativas de computação em nuvem e Kubernetes tem se destacado como o sistema de orquestração de infraestrutura virtualizada. Entretanto, essas plataformas não foram projetadas para suportar nativamente os serviços em 5G. Para ilustrar, Kubernetes foi planejado para ser agnóstico aos serviços que orquestra e não é capaz de reconfigurar o núcleo 5G dinamicamente de acordo com os recursos de rede existentes, i.e., provê uma orquestração dinâmica parcial para realizar um fatiamento da rede. Este artigo propõe uma solução integrada ao Kubernetes para permitir a orquestração dinâmica total de fatiamento de rede em tempo de execução, ajustando núcleo 5G. Essa integração é realizada através de um controlador integrado ao Kubernetes e de um proxy de plano de controle. O controlador é capaz de ajustar o núcleo 5G e adaptar a infraestrutura virtualizada, enquanto o proxy cria uma abstração para a comunicação de controle entre as redes de acesso e transporte com o núcleo. Os resultados experimentais apresentaram uma reconfiguração na orquestração dinâmica total sem interrupção dos serviços, reduzindo em 47,5% o número total de requisições de reconfiguração por fatias de rede.
