The framework progresses the means made available by different standards and research initiatives to enhance service requesting and provisioning interfaces for the stakeholders involved, namely operators and verticals. The framework is validated under two different use cases, showcasing effective end-to-end service instantiation and a first assessment towards dynamic service modification capability.7eng© 2021, IEEE.Interdomain5GSlicingNetworkconference proceedingsTelecomunicacioneshttps://doi.org/10.1109/NFV-SDN53031.2021.9665037open access1541602021 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN)
