Summary:
|
The E2E network slice usually is over a complex network environment. To support an E2E network slice instance, a combination of networking technologies, such as SDN, NFV, cloud-native computing and hard slicing technology, are necessary to adapt the diverse features of multiple network domains. Furthermore, the multi-vendor and multi-stakeholder infrastructure increases the complexity of the network slice, specifically in the resource orchestration. The network slice faces the challenges regarding the inherent trust in the multi-domain, multi-vendor and multi-stakeholder environment.
The confidential computing based on hardware-based Trusted Execution Environments (TEE) could be used to help meet challenges associated with protecting data in use. Through this hardware-level isolation, the TEE provides a level of assurance of key properties including the data confidentiality, data integrity and code integrity. ITU-T SG13 has started a draft recommendation Y.CCO-req, which focuses on the study of the requirements of orchestration supporting confidential computing for network slices in IMT-2020 networks and beyond. As in the architecture of orchestration supporting confidential computing for network slices is proposed in Y.CCO-req, enhanced logical interfaces and new interfaces are introduced, thus the signalling requirements and protocols of the interfaces are required to be further studied correspondingly.
The new work item aims to provide the signalling requirements, protocol procedures and message format of the interfaces in the architecture of orchestration supporting confidential computing for network slices.
