“…• NS architecture: Several papers (Afolabi et al, 2018;Foukas et al, 2017;Kaloxylos, 2018;Barakabitze, Ahmad, Mijumbi, & Hines, 2020) describe the NS architecture, which is composed of infrastructure, network function and service layers (Next Generation Mobile Network (NGMN) Alliance, 2016). Depending on the layer, NS isolation can be done in many ways: software-based isolation, physical isolation, and virtual machine-based isolation (Kostopoulos, Chochliouros, & Spada, 2019). For this purpose, the Next Generation Mobile Networks (NGMN) Alliance ( 2015), establishes for each network layer the following instances: 5G service instance layer (5GSIL), 5G network instances layer (5GNSI), 5G physical resource layer (5GRL).…”

“…In recent years, we have witnessed the rapid growth of the Mobile Telecommunications Market, thanks to the strong implementation of fourth-generation (4G) networks and the development of fifth-generation (5G) networks [1,2]. This has enabled the introduction of new business models and innovative types of services [3]. Furthermore, the architecture flexibility and scalability of those networks allow sharing any sort of network resource between Mobile Network Operators (MNOs) and Mobile Virtual Network Operators (MVNOs).…”

“…Hoy en día el crecimiento del mercado de las telecomunicaciones móviles, gracias al masivo despliegue de redes 4G y al desarrollo de las redes 5G [2,3] han permitido la introducción de servicios innovadores y de nuevos tipos de MVNOs [4]. Así mismo, la evolución de las redes móviles ha reducido las barreras para la entrada de los MVNOs y ha facilitado las asociaciones entre MNOs y MVNOs [5].…”

“…En varios documentos [75,81,82,85] se describe la arquitectura del NS, la que está compuesta por las capas de infraestructura, de función de red y de servicio [89]. Dependiendo de la capa, el aislamiento de los segmentos de red puede realizarse de muchas maneras: aislamiento basado a nivel de software, aislamiento físico y aislamiento basado en la máquina virtual [4]. Para este proposito el NGMN estableció para cada capa de la red una instancia [66,90].…”
